Remapped my E92 M3.
Discussion
So I had my E92 M3 re-mapped yesterday. I must admit, it doesn't feel much different! To be honest I wasn't expecting startling gains, but thought I would have felt more of a difference. It feels a little "faster" due to the rev limiter being increased, therefore seeming longer in the gears. The limiter is raised to 8500rpm, and the 155mph speed limiter should now be gone. The BHP is now meant to be 449 BHP and the torque is meant to be now 324 ft/lb.
Has anyone else had theirs re-mapped?? I would be interested in opinions.

Hi Rash Decision,
Pardon the pun, but sounds like you made a rash decision !
I see some areas of concern of what you've reported here, so..
1. Who did this 're-map' ? was it one of the very top end tuning companies in the UK? or was it a 'we do re-mapping' as well as MOT's and valeting your car type places? or was it the lowest of the low and some sort of ebay add on box?
2. Did you do any before and after comparisons ? also perhaps with another known test/benchmark car ?
3. Did the company or person used have the right equipment and experience? or was it a mate of a mate?!
4. Can you get your money back? if so, spend some time researching the very best re-mappers and tuning companies who do these cars every day...
if not, I think you need to kick up a stink as they've not delivered the expected enhancements and have 'potentially' at this stage (at worst!) put on a re-map which will cause more harm than good.
Cheers, Dennis!

It was a friend who is an agent for one of the larger UK based companies, who I would like to remain nameless at the moment, but has a good reputation. Getting my money back isn't an option, as it was done for free!! So I'm not too fussed that it doesn't now achieve Mach 2! Of course I have a before and after comparison, I drove the car in a standard state, then drove it in a re-mapped state! Surely that's comparison enough?? I can't really see what harm it can do? If anything all they do with these maps is up the fuelling and let the ECU compensate with the air flow??Pardon the pun, but sounds like you made a rash decision !

449bhp sounds extremely optimistic to me. It's a NA engine after all, most maps from reputable companies seem to promise about 10bhp.
Most of the companies I looked at quote 449 BHP. Maybe it is optimistic, but it was free. If I had paid, then maybe I'd have been more upset?? But an NA engine at 420 BHP already will never gain all that much in rality from just a remap. Exhausts, CATs and Induction really need to be changed to see real gains, then it's gotta be internal to gain any more!!Edited by rash_decision on Wednesday 18th August 18:58
Just for info, Evolve are a very well respected tuner for BMW's, and they say this on their website regarding the E92:
"ECU remaps on their own will never give 440bhp (unless tested in the wrong gear). What they will do is sharpen the throttle response and give gains of around 12-15bhp above 5000rpm. The lower rpms will gain only a small amount of torque."

Hi Rash Decision
Fair enough you'd like the company or person who did the work for you to remain nameless. You got a map for free, so I wouldn't be surprised if all he 'actually' did was change a few settings/parameters here and there.
If ECU re-maps were as simple as that, we'd all be strapping superchargers onto cars during our lunch breaks!!
No, Engine ECU re-mapping is much more involved than that when done properly, of course there's half arsed and limited attempts out there, like any industry, but thinking that a airflow meter parameter change and fuelling increase forms the basis of a reliable and proven power increases is simply totally incorrect.
I did laugh at you saying the before was you driving the car and the after was you driving the re-mapped car as a comparison basis! I 'see' why you've said that, but take that to any well respected tuning company or should you wish to prove the gains you'd be severely laughed at!
In a nutshell, it doesn't sound as though your Free re-map has benefitted you or your car much at all, which is what I'd expect from a freeby job, I'd also hazard a guess the mate who did it plugged his laptop in, pretended to look engrossed for a length of time and then said there it's all done
I'd urge you to read up on the UK most respected tuning companies, call them, ask them what's involved and what you can expect to gain from just the re-map and potential other enhancements that'll bring out the 'best' in the re-map, talk to other's who had 'proper jobs' done, ask questions and read independant reviews to begin to understand how the high tech and knowledgeable specialists do it.

This page on the evlolve website is quite informative:

I looked at getting my own car done, but the cost and loss of warrenty for the meagre gains just don't stack up for me. The moneys going on the next car instead.

Re-maps can and do work, well, with a whole host of cars. I agree that there is more involved with real gains etc etc, but I can also understand that a tuning company can re-map a few cars for experimental purposes, find a generic map that works, and use it on other cars. I'm quite sure that every E92 M3 that rolled off the production line has the same ECU program, with some updates along the way.
My mate never for a minute pretended to be engrossed or deeply involved in any way. In fact the whole process took 10 minutes from reading the file from my ECU, then writing the modified file to the ECU.
Why is driving the car before and after not a fair comparison? After all, it's not all about horse power figures in the end. I had my 911 C4S remapped as I felt it a little flat in the mid range, incidentally by the same company. When the guy on the phone tried to talk numbers, I stopped him and explained that I wasn't interested in standing in the Halfords car park bumming about BHP figures, but mearly wanted to iron out some issues with a flat spot. So re-map done, no flat spot and the car was nicer to drive.
I had no real issues with my M3, I just thought I'd give it a go and see if it "improved" an already very very good car. But as i have stated, there's really not much in it!
To be honest, I'd be very surprised if anyone can gain much from this engine, or any others in a similar region of performance. N/A engines never really have benefited that much from a re-map, but hey ho, it was free!! In fact, I'd be surprised at the ammount of folk out there who have had a re-map carried out, with no real gains, but go away with the phsycological thought that there car is way faster than it was before!! My mate sent a car out that hadn't been re-mapped by mistake! he only noticed when he went to his car park to bring the car in, but one of his mechanics had only serviced it, as per customer's instruction, and sent it back. When my mate called the guy to expalin and get the car back in, the guy was all too quick to coment on how much better his car was!!!
Hi Rash Decision,
All valid points, and everyone is different of course. I to am not really concerned with saying mine has X power what about yours etc etc. I like to be a bit more discreet with that kind of thing too!
It does come down to preference, When things are 'cheap' or 'free' they do 'tend' to be on the 'skimped' or 'corner cut' type - re-maps included. There is alot of 'unknown' talk out there when it comes to this kind of thing. However, I along with 99% of BMW and other car's enthusiasts I've spoken to who have such high end cars, prefer to have work done on our cars by reputable and knowledgeable specialists - from my power steering belt change to re-maps and possibly forced induction etc etc. In your case, you are happy to have just removed flat spots and any power gains are a bonus. This is normally the case on N/A engined cars, the driveability and responsiveness is usually noticeably increased and a bonus in kind is usually 5-10% more power. It's nice to see what the car was doing prior to the re-map and then after by way of dyno testing so you can actually see the results. I bet had you had actually paid say £350-500 for this work, you'd also have insisted on it! - unless of course that kind of money is chump change to you!!
If you'd explained perhaps this in your initial post, it'd have been clearer into how you like your car and your requirements, however on the face of it, it appeared that you got a free re-map and didn't think much of it, which instantly smacks of a bad job, especially on what's a fantastic £40,50, 60 grand car !
Hope your guy didn't just 'fuel' it different either - over the next month or two, observe your MPG both indicated on the OBC and in real world comparisons. As you don't really know what was changed etc, you are on an bit of an unknown on it.
Cheers, Dennis!

I can't really see what harm it can do? If anything all they do with these maps is up the fuelling and let the ECU compensate with the air flow??

Changing the advance in order to generate more power may cause the engine to pink. Thats why higher stage maps need higher octane fuel. Its not as simple as just chucking more fuel in.

Yep had my E90 done it made 30BHP more and pulls like stink, it's transformed mine, who did yours?. I left the REV LIMIT alone, it does not need more revs.Has anyone else had theirs re-mapped?? I would be interested in opinions.

Let me know the tuner that gave your na M3 an extra 30bhp and proved it reliably and i will get my M5 with headers, 100cell cats, "x" pipe and H&S back box's putting out an extra 29 bhp tested before and after.
And i should hopefully see at least 450bhp, oh how i laugh!!!
You are talking at least a 7% increase in power, go figure!!
