The final word on the BMW 335d remap before she goes – Remaps UK.

By Andy Percival

The BMW 335d Remap Project

The truth is after the BMW 335d remap project finishes, we haven’t got a clue where to go now, what’s next or how to better a fully performance Custom tuned remapped BMW 335d!

This has been said many times in the office, a remapped engine tuned BMW 335d remap, is a all things to all men, It’s luxurious, sleek, super quick, economical and a hell of a lot of fun and most surprising of all its a diesel!!

So what do we choose as our next project car? Where do we go from what we consider here at Remaps UK to be the apex tunable diesel currently available in the market, that is the BMW 335d?

If all this is sounding a bit confusing and isn’t making to much sense, then allow us take you back a few months, back to the beginning where it all began…..

A few months ago we decided to finally put our BMW 335d through a full top down engine tune and top of the range live custom remap upgrade, it is worth pointing out that no physical components were changed what so ever in this project, just software modification (ECU mapping and recalibration) in order to achieve the results. This would put the Remaps UK’s  BMW 335d remap to the test and hopefully answer some of the long talked about and unanswered questions. Questions like how much bhp can realistically and safely be unlocked by engine tuning and remapping whilst maintaining good economy and German reliability? How many torques could we unlock? Would it break the dyno? All these questions would need to be answered before we could move on in our lives and move away from the sleepless nights of worrying about all the answers!

Thankfully the answer wasn’t 42 either!

BMW 335d Remap
Strapped down like a Raging Bull!

The first figures that we took from the remap project BMW 335d were the stock ones, in stock form the Remaps UK BMW 335d was an impressive 294 bhp, which was 8 bhp up on the standard BMW 335d figures of 286 bhp, so a thumbs up from BMW there ( to be honest this didn’t shock us as we see this all the time with BMW).

We did a total of 9 runs on the dyno before we decided that, 1, the dyno had had enough, 2, the tyres had also had enough and 3,  we wanted to test the results, in a safe and scientific manner of course!

Each run brought us new data and highlighted new areas we could work on in order to achieve the ultimate remap tuning file and produce a blueprint for the BMW 335d remap.

The finished results were nothing short of staggering, it’s important at this point to highlight a few things, we have no doubt there was a hell of a lot more to give from our newly remapped BMW 335d, but felt that the end result was just enough and would still remain safe and reliable for every day use and for years to come (we will never over tune a vehicle in order to quote high figures to get peoples custom! Remaps UK is  all about quality and power delivery).

Ok, so what figures did we get?

Join us next week.

just kidding, I’ll cut to the chase.

The Final Run For the BMW 335d Remap

On the final run the dyno recorded a max engine power a figure for the remapped BMW 335d of 366.5 (flywheel) bhp and max torque figure 734 nm (541.9ft/lb) !! A stock bhp is 286 and 580 nm!

Nice smooth curves!! @ the Wheel Readings in Green

To put all this into perspective, and we feel it does need to be, take for example a Ferrari f430, this develops somewhere in the order of  465 nm of torque, or a McLaren F1, 649nm, maybe a  Lamborghini Murcielago , which has 660 nm worth of torques under its bonnet. In fact the only realistically priced and semi attainable vehicle we found that came close was the Dodge Viper SRT-10, which has 759 nm of torque, which subsequently  needs an 8.4 litre V10 engine to produce it! Now our little BMW 335d 3.0 l straight 6 pot diesel sounds pretty impressive don’t you think?

bmw 335d remap graph
Max Eng is @ flywheel reading, same as the manufacturer figures, Lower figure is at wheels

What we have done here at Remaps UK is create a monster, there is no other way to put it, put this thing along side anything short of a super-car and it will honestly without hesitation annihilate it, the performance is biblical, it’s mind bogglingly quick, and to top it all it’s a diesel!  We always knew a detailed and developed  BMW 335d remap was something special, but nothing prepares you for the performance of a remap tuned 335d, especially if it’s a Remaps UK one!

The pull through the gears from standing start is phenomenal  as the waves of torque push you firmly into the seat, third and forth gears are unbelievable, with the now removed speed limiter this thing is capable of 185 mph! Yet drive the car sensibly, which we know is very very hard, and it behaves perfectly, super smooth power delivery  and increased throttle response make it feel like a petrol car,  but with better mpg!

‘As with any BMW, the way the 335d delivers is power and speed is very deceptive, we gasped down at the speedo in shock at how quick things got in our Remapped BMW 335d!’

Which brings us onto this next section of the project.

Economy on the BMW 335d Remap Project?

We filled up the tank on the 335d and recorded a range of 585 miles, and averaged an mpg figure of 38.9. Yes you heard right, 38.9 mpg. All this out of a 370 bhp remap tuned 335d engine! We honestly believe there is not another car in the world that can do this, that performance with that efficiency!

So ,now you see our dilemma, where do we go from here, what else is out there that comes anywhere near to the 335d as an all-rounder.

The short answer is nothing.

Nothing comes even close. BMW have created a fantastic engine with the sleek lines of the E92 coupé to match, and bullet proof German engineering. Remaps UK have taken this image and created a truly unique, one of a kind BMW 335d masterpiece, of which we have grown very very fond of.

This project will be thought of and talked about for many many years to come, I’m sure.

We gonna miss our awesome remap tuned BMW 335d!

Remap Problems – The Hidden Truths Behind the Remap Engine Tuning Industry

Remap Problems, cause and effect ?

Remap problems press release.

In an already overly saturated market place the Remap Engine Tuning industry has already seen its fair share of winners and losers, from catastrophic engine failure to minor niggles, all are most unwelcome in the Remap Engine Tuning Arena.

With so many companies out there it is Very difficult to know where to even start, never mind who you choose to trust to remap your £50,000 new motor car.

With many new companies popping up almost over night, it can be a real mine field out there.

Get it wrong and it could leave you sat on the hard shoulder in a cloud of black smoke with your head in your hands wondering what happened and where you went wrong. Remap Problems

One company out there is claiming it wants to try and change all this and try to reinstall some confidence back into what is a great industry, the company is called Remaps UK.

Based in Cheshire Remaps UK is a custom remap engine tuning company based in the North west of England, providing a mobile engine tuning service across the UK . They consider themselves the experts when it comes to economy and custom written performance remap engine tuning. From economy to race Remaps UK can custom write ant spec of file you require!

‘Remap Problems – Remapping isn’t easy, it’s a specialist skill’.

Company owner and technical director, Andy who has been involved in the tuning, programming and automotive industry for the last 20 years was asked about his experiences from within the remap tuning industry and about his experiences with remap problems, he said “I have lost count of how many calls I get a month from customers who have picked price over product and found themselves with a car that won’t start or even worse a blown engine…” he went on to say “ This really is a highly skilled industry with far to many individuals setting up shop, buying the kit from a particular ‘online’ auction site with a disk full of various generic remap files, building a website and buying a ‘Pay & Go’ mobile phone and now consider themselves a Remap Engine Tuning Expert…and the thing is, they are getting away with it. Walking away with your money, leaving the unlucky ones out of pocket with a broken car sat on the drive and a bunch of remap problems and vehicle issues to sort out…it really isn’t on!”

Pushed further about the remap engine tuning industry and remap problems Andy revealed some shocking stories of customers who have contacted Remaps UK with there remap problems and experiences. Andy also spoke about customers Remaps UK have worked with to help get back on the road, he said “ we had one particular customer, really nice gentleman who called Remaps UK for a performance remap engine tuning quote, he stated he had found a cheaper company who would do the work for him, after explaining how we do things here at Remaps UK, explaining all our remap files are live and custom written on the day and are not a generic file, that we also have a £2 million Royal Sun Alliance backed warranty and that all our files are created by us, developed by Remaps UK here in the UK, he still chose to use the Alternative cheaper company” he continued “ a week later the same customer contacted us here at Remaps UK stating that the remap engine tune that was done by the other company wasn’t a total success, in fact the whole ordeal was a complete failure, resulting in the vehicle not starting at all!” he added “the said remap company, allegedly remap tuned the car, which was in fact an 2008 Audi A6 2.0 TDi 140 bhp, then told the customer it needed to reboot and would take 30 minutes to complete, took the customers money and left the premises…the customer tried the vehicle, which then failed to start, tried to contact the said company and found the number was out of service and within hours the website shut down and gone!”

Andy at Remaps UK went on to explain, stating “ The customer was understandably in some distress about the whole ordeal, he was also annoyed that he’d allowed this to happen and wondered how he’d ended up with these remap problems” , he went on to explain “the previous remap tinkerer had totally fudged up the remap, pushing a generic file onto the ECU (after analysis we found the file that had been written was for a totally different engine code and model which created the remap problem for the customer!) we had to do a total rebuild of the ECU from scratch….” and added “ luckily for the customer we’re probably one of the only few remap engine tuning companies in the country who have the expertise to do this and what’s more we stood by our initial price quoted, even though our work was doubled…we felt it was important to go the extra mile for the customer without the extra cost, plus he’d already had enough problems for one week, it was now up to us to put the smile back on his face…we think he learnt his lesson ”, “ needless to say the customer was over the moon with the finished result and no more remap problems, he was also and very, very, thankful if somewhat a little embarrassed ”

Other remap problems are also common place he went on to say “ we have visited cars with the wrong map installed, we found a remap file for an Audi 1.9 tdi on a vehicle that should have had an Audi 2.0 tdi file, a Mercedes Benz SL55 amg with a remap file for a SL500, the list goes on, but one thing the customer probably wouldn’t find out about is the fact that we have had previously remapped vehicles in that have had the vehicle immobiliser codes erased! Which means anyone with a key could start your car” he added “we even had a BMW 330d which had been previously remapped by another company, the customer still had the flat spot in the rev range that he wanted removing in the first place, when we analysed his ECU we found no upgraded had been installed whatsoever even though he’d paid for one! Now that’s just a ridiculous exercise in maximising profit at any expense, this really annoys and angers us here at Remaps UK, and is potentially damaging what is inherently a great industry”

Remap Problems & Dangers – with great power comes lots of problems!

This story is becoming all too common, but what is being done to stop it? How can this be avoided in the first place, we asked Andy what the future of remap tuning was likely to be and what Remaps UK as a company were doing to bring back customer confidence. He said “ Good honest business, in short, we invest heavily into our equipment which allows us to produce and develop what we consider the highest quality remap engine tuning files available” he also added “through painstaking hours of testing we have come up with and un locked some of the most hard to tune vehicles out there in the industry, with fantastic results…improved economy, reduced carbon footprint and increased performance, these are all achievable with a reputable Remap Tuning company”, “ the key to good remap tuning is time invested and experience gained through rigorous testing anRemap Problemsd development, which all in all costs money, without the investment, we could not produce the high calibre remap files that we do” , ”with big advances in Engine management technology the new breed of remap tuning is becoming more and more intricate, you really need to know what you are doing, ask questions to see how far the Remap Engine tuners knowledge goes, what the tuners background is? How long have they been in the remap engine tuning industry? all really simple things, but rarely get asked once the customer has been offered the deal of a lifetime and more bhp than a Veyron! If the deal sounds too good to be true, it usually is” he added “ or course, ultimately the choice is down to the customer, you have the right to choose, just make sure it’s the right choice”

So what started out as an insight into the dark and gloomy world of Remap Engine tuning and remap problems,  looks set to be a brighter place, with the right company, if chosen carefully?

Andy went on to explain “ the benefits of remap tuning far out weigh the minority of budget end low grade remap tuners out there creating the majority of remap problems…” he continued by saying “with a high quality remap upgrade customers can expect increased throttle response, better fuel economy, reduced carbon emissions, better performance and smoother power delivery, just make sure you pick a company you are comfortable with and you will become a happy member of the remap tuned vehicle club and not the remap problems one!”

The Remaps UK BMW 335d remap project nears it’s end…

The Remaps UK BMW 335d remap project nears it’s end…

and it’s been emotional!BMW 335d Remap

For those of you have been following the remap story of the BMW 335d remap E92 Coupe, it now approaches the end of its run and also marks the end of all the fun we have had with this truly outstanding vehicle.

Mile after mile the BMW 335d remap gave us smiles!

We covered over 5k miles in our 335d remap project car, from a stock bhp of 286 right through to the performance blend remap which took it to figures to 325bhp. May we also add, that we loved every single mile, every second of it’s 0-60,  in fact we found it very hard to put down the keys, and even harder to sell this on!

The BMW 335d remap Proof is in the pudding or on the dyno!

The final run for the 335d will involve a full day on the rolling road and a final custom race remap tune to really see what the BMW 335d is a capable of, we know from experience that the straight six is a phenomenal engine and that higher figures are more than within the tolerances of the BMW 335d, but as I am sure you are aware, we here at Remaps UK love to get the balance just right in terms of performance and economy. On this remap tune though, we are throwing the rule book out of the window! And i for one can’t wait!!

Watch this space for the final chapter in the life of the remapped BMW 335d by Remaps UK.

We Also Remap engine tune BMW 535d remap, BMW 635d remap, BMW x5 remap and BMW X3 remap!

Project BMW 330d Remap Three ECU remap options & three fantastic results.

The BMW 330d Remap Project

Project BMW 330d Remap330d remap

With fuel prices soaring and the green brigade telling the motorist to drive around in electric yoghurt cartons and organic ones at that, it would seem that the UK is fast approaching a society where the performance hungry driver has no place in the universe, let alone on this planet, or does he?

Performance has always inherently been related to the thought of huge turbo’s, V8’s, petroholic 5.0 litre engines that suck in small animals through the air filter and spit a raging pit bull terrier out of the back!

But this has changed and the Germans were quick of the mark.

Seeing a gap in the market German manufacturers like BMW and VW/Audi invested heavily into the research and development of the diesel, yes they smell funny, they smoke and scare small children, but hear me out. The new generation of diesel engines doesn’t do any of these, in fact they do quite the opposite. For instance take a look at the exhaust pipe of the new BMW E92 330d for instance, its spotless and I really mean spot less. Take a listen to is straight six cylinder engine and one could be fooled into thinking its actually a petrol and a meaty one at that. Then get behind the wheel and one will be simply amazed at the performance and shocked when one sees the MPG figures reading near 50 mpg at motorway speed! BMW claims the 330d has a Combined figure of 49.6 mpg and kicks out 231bhp, with a 0-62 of 6.7 secs, now that doesn’t sound very diesely does it!

All good things – BMW 330d Remap

Andy at Remaps UK Ltd in Cheshire said , “I thought I’d let you know about a little project I’ve been running for the past few months” His project was aptly named Project 330d Remap … the clue is in the title”

The project vehicle in question is the new BMW 330d Remap E92 Coupe, with the tiptronic box, Andy at Remaps UK says, “this is the best engine and gearbox combination for the tuning method we are going to use, as the torque figures this engine produces would make mince meat out of a manual gearbox’s clutch’ and added ‘for the economy remap or a performance economy remap blend, the manual box is more than capable, it can also handle a performance map without any problem, but, what we have planned is full race, and lots of brake horses, and lots of brake horses, unchecked can break things. ”

330d remap

Andy and the team plan at Remaps UK is to run the BMW 330d remap project on 3 different remap options, firstly the economy remap, then the performance economy blend and finally a full blown race remap.

The economy map was developed after many different evolutions of the old E46 maps, Andy went on to say “the old E46 330d 184 bhp and BMW 330cd Remap was a fantastic motor and paved the way for the new breed of modern diesel engines… we had some great fun tuning the E46 all those years ago and took great pleasure looking at the shock on the M3 drivers faces after a show down at the lights! Especially when they saw the badge Diesel ! The E46 still has a big following today and for good reason, it can still hold its own against the big boys and is still a very tunable and capable machine, in fact was one of the best re-mappable vehicles until its newer younger brother came along, Project 330d remap ”

When the final evolution of the Remaps UK remap file for project 330d remap was finished and installed on the eagerly awaiting BMW E92 330d Coupe the first thing that was noticed was the mid range punch, and also the extra 28bhp it got! This car now drives and feels like it should have done from the factory. On its first decent motorway run figures where rarely under 64mpg! At one point the vehicle range showed 760 miles. On a 3 litre diesel these figures are truly staggering when you consider the speeds as well, ahem!

Andy went onto say, “over the years we have seen a shift in trends on what customers want, 3 years ago we rarely sold any economy maps as everybody wanted performance remaps, but as we developed the various remaps we instantly noticed the increase in engine efficiency even of the performance map. It seemed the by-product of all the performance maps we did, gave a significant improvement in mpg. It was at this time we diverted funds into this development area which finally produced the remap option we now call the blend, or the best of both world map option which is the performance remap and economy blended together like a good whiskey” He also added, “now with soaring fuel prices we can provide a significant quality remap solution whilst improving your mpg as well, having your cake and eating it springs to mind. ”

Onto the performance economy blend remap option and the most popular choice for today’s customers according to Remaps UK, Cheshire. Andy explained, “this map is probably the best bang for buck for customers wanting the extra performance without the extra running costs, in fact this is the opposite, it costs less and you get a lot more. ”

In fact the Project BMW 330d remap Coupe got an extra 48 bhp taking it to just under 280 bhp, Andy stated, “this level of performance increase is right on the balance or performance against increased efficiency, it is a knifes edge and takes a lot of skill and experience to get it just right, trust me on this one, the testing and development was extensive, but the finished results are fantastic. Performance is nothing like the car in standard for, it breathes so much better and sings so sweet when you open up the taps, yet take you foot of the gas mpg figures shoot up with a combined average up 8 mpg over standard… very very happy with this result, the BMW 330d remap ed is a truly outstanding piece of engineering and is growing on me from day to day. ”

Its all about balance…Project BMW 330d Remap

Finally Andy at Remaps UK unleashed the full race remap option on the new Project BMW 330d remap Coupe, he said, “this is what we would consider a stage one pro race remap and would be considered for track use or the like, there is a lot more in there to give, but as I have mentioned before it has to be drivable and reliable, this map ticks both of these boxes” Adding, “there is no point having the car just sitting at the first set of traffic lights with its tyres smoking whilst the guy in the tuned up Corsa pats himself on the back and heads to the pub to tell his friends of his easy victory, its all about balance. ”

With great power… blah, blah, you know the rest – Project 330d Remap

He added a few cautious words of warning though, “engine tuning and remapping is most definitely an art form as well as science and engine tuning understanding, there are many companies out there set-up overnight supplying unrealistic figures and low prices which bring in the not so clever punter, if you don’t know what you are doing it can all go horribly wrong. ”

So, how did it perform, in short the results were unbelievable, the transformation was truly astonishing. The sheer acceleration pins you into the back of the seat in what can only be described as a complete assault on your senses. The power delivery is so smooth whilst being progressively aggressive in the same breath, it feels like a totally different car. “we’ve created a monster” Andy added with a smile.

330d remap

The rolling road showed the Project BMW 330d remap car pushing out just over 300 bhp, 306bhp to be precise, but it felt a lot more. Andy said, “this has to be one of the best tunable engines out there at the moment, BMW and Audi with both of the 3.0l blocks have hit the nail smack bang on the head, you just can’t go wrong with either, superb performance and fantastic economy” He continued to say, “me personally would always go down the route of the BMW as I prefer the driving characteristics and balance of the chassis, but still hold a hell of a lot of respect for the Audi’s. ” He stated, “the performance of the race map is in another league, we took the car up to the Lake district for a weekend run, the car averaged 58.8 mpg on the motorway at proper cruising speeds, if you know what I mean” And added, “the on road driving characteristics were really impressive, of the mark nothing could touch it and 3rd gear is epic” He also joked and said, “think the guy in the 335d wondered what was wrong with his car, sorry” and continued to say, “all in all a thoroughly enjoyable remap test, very impressive results across the board” finally adding “now to get hold of a BMW 335d Coupe to work the Remaps UK Magic on. ”

Andy finished by saying, “It has been my pleasure to take the time to explain the ins and outs of this project and I have hopefully given a more detailed insight into the world of engine tuning and remapping, It has been a very enjoyable project and have loved every minute of it.

Many thanks from all the Remaps UK Development Team, now, who’s got the keys to the Project 330d Remap vehicle? ”
