What do BW chiptune charge for a remap?

Would like to use them as would get some pre/post dyno figures but they are miles away opposed to simon @e-maps

[Sir_Dave]

I was quoted the following last year, prices may have gone up since:

If the car is before 2009 the it will cost £350 remapped on the dyno
After 2009 on a e92 is £400

got mine done as a favour,,£300 and that was done via a live link,,but ususally £350 as said,,i had 7 dyno rins..2 of them stock to see where the car was at and diagnostics to see if car was fit for remap.

give him a bell,,and he will tell you where his closest remap centre is,,he has a few around the country that use his maps etc,,and have a dyno,,then he can do it via a link to him,,i had mine done and i live 350 miles from him.

The problem with BW Chiptune are the shitty reviews which seem to happen if you deal with any of the sons rather than Jason himself.

never dealt with sons,,only jason,,but never heard any bad reviews really..he also knows better than anyone about remapping bmw cars...especially the egr off etc..

I asked dervtech about egr off. He said that the EGR was used to build exhaust tempt and help regen the DPF. Without this, the DPF could/would struggle with regen, so for stage 2, it had to have DPF delete.

How much truth there is in any or all of this, i don't know.

Either way, im happy with the map and the car feels much better.

[kash330D]

by the way, for me, stage 2 was a competitive price and i went on a recommendation from someone who is a total petrol head.

Can't say I've seen a bad review. When I went there, Chris (his son) and another chap (can't remember his name) did all the dyno and prep work, and Jason did the work when it came to actually working on the ECU. All three of them were great, very friendly and chatty, and more than willing to answer any questions - of which I had a lot!
Was a bloody long day and it would've been nice to watch Jason when it came to working on the ECU, but this was understandably off limits as due to the technicalities and concentration required. He literally spent somewhere around 2hrs on the ECU.
The only criticism I would have is that the workshop is just like a typical small garage - shit everywhere which I wasnt expecting. Looks can be deceiving though cos these guys really do know their stuff.

Not so sure that is correct. I've been running a bluefin map for over 20k miles now, they also added the EGR delete for me as I was having troubles with the vacuum controller making the car stutter. So EGR delete definitely working. My car has been doing regenerations with no problems at all, mostly passive too as the you never see it kick in with the usual heavy fuel consumption and increased temps. Carley shows low soot and ash which confirms it's working OK. This would not be happening if the exhaust was not getting up to temp. I live in North London and commute round the north circular so plenty of slow crawling in traffic together with some decent long runs at 50 to 60 mph.

total bullshit,,i will put what jason has developed https://www.bimmerforums.co.uk/forum...tware-t474769/ just shows they do not know what they are doing,,should be derrrrrrrr tech!

[kash330D]

well, alas, it is done now, and like i said, the car goes like a train and seems to run fine.

I read lots of other tuners posts/sites and many said a similar thing. Jason might be on to something but hey... such is life.

[Sir_Dave]

Its because Jason can actually remap an ECU from scratch & load a variety of different parameters onto it, whereas others may do more of an "off the shelf" map, so the deeper knowledge simply isnt there. Its a bit like buying a Chinese from Waitrose vs. your local takeaway, in both instances you get some Chinese food, but only one is done properly, from scratch, with years of knowledge, while you wait.

Found this was very much true in the Mini R53/56 and Clio 1*2 world over the years, some really know what they are doing, others simply claim that they do

100% agree.

Approached BW Bumtune and they were totally unprofessional. Plus as someone has mentioned there workshop doesnt give you much confidence.

In the end I went to Evolve which was a much better experiance. Look at the latest products by Evolve, they are probably the best in the business.

Dervtech are aware of this thread now after I sent it to them. Wouldn't normally copy and past PM's but im not sure it's fair to say that any/every other tuner doesn't do it right because its not the way BW do it. I'm not taking sides but i'm sure each tuner has their ways - 'you can build a house in many ways'.

Their response:

Interesting to read other people run egr delete with dpf still in place. The way we do the egr delete means that the dpf wouldn't regenerate. It might be that BW adjust the dpf temperature thresholds as part of their removal of the egr to ensure the dpf continues to regenerate. In my opinion, you don't want to put yourself in the position whereby the dpf may not regenerate because the EGT isn't hot enough, all because you did away with the EGR. As said though, everyone does things differently.

BMWs are our bread and butter, diesels too... you sill find (if you ever looked at the map on your car) it’s absolutely, 100% custom to you, and is properly calibrated as per the manufacturer.

jason writes his own files and does the egr delete byte by byte.... not a lot of tuners are able to do this as its not straight forward and takes a lot of years to study and gather correct knowledge,,ecotune are very good also at tuning cars this way etc

Unless someone has driven the same car running different tuners maps your not really going to know how much better one tuners map is over another.

I run a quantum map on my 35i which was also installed via a 'live link' & obviously I think it's great but I have no idea how it would compare to another tuners map

there is quite a bit difference between a a map which is just thrown onto a car,,than a map which is data logged then tweaked to suit that particular car..also its in the way its written,,so many parameters that i get confused...like the egr off inthe map,,lots most tuners do not know how to do it,,so they tell folk to get rid of egr by blanking it,,or egr coolere removal etc,,but it aint nessescary if you know what you \are doing.

Yes there is a difference between a custom map on a rolling road compared to a generic remap. But my point is unless you've driven the same car having had various remaps on it you're not going to know which map or tuner is better.

I’m sure there will be difference BUT two identical cars, no mods serviced and maintained reasonablly will perform almost idecially out of the factory what makes a custom map better?

Not disputing the fact that some tuners have better maps than others but just the fact of how ‘custom’ will/can it be for 2 similar cars?

Well I'm no expert but I would surmise that a custom map with the tune being loaded whilst the cars on a rolling road would allow parameters to be measured & being able to make adjustments to achieve optimum performance.
You can buy a map from one of the main tuners which would have spent a lot of time perfecting or you can go with a guy that does the remapping based upon his experience & knowledge but as with everything some will be better than others.
There are those that state Jason at bw is the place to go to but I was just curious as to how many other tuners maps they had tried
