Re: I had my 525 ECU remapped recently!
I've seen many similar comments that led to me think that the improvements perceived by users are due more to modified throttle mappings rather than actual HP or torque gains.
Some drivers who tuned their ECU's, but disabled the throttle remapping, noticed that HP/torque gains (by themselves) were marginal. The most obvious "improvement" came from the more sensitive throttle map. It would be nice if NA engines could be tuned to have more actual power, without risking long-term damage.
An engine definitely feels more responsive and exciting when it can climb to high revs when the accelerator is touched slightly, but I do find the stock throttle map allows for more gradiated control over the throttle.

Re: I had my 525 ECU remapped recently!
ya, in short - more power rather than just a more sensitive throttle
one way to know the real improvement other than doing a dyno is getting a reference car for comparision.
my 523 lose out marginally to the older E230 and A4 1.8T in standing start and during high speed acceleration.
i'm looking for a chance to test out with these 2 cars now that i've done the tuning to see if its true.

Re: bmw ecu remapping
Hey Jonsuta
I have exactly the same experience as you. I also have E90 323i and did remap with Dave Naidu of OBD Tuning two weeks ago. After driving remapped car for a week, could not feel much difference so sent email to Dave to tell him so. He has not replied to my email. The remap is supposed to convert 323i to 325i spec. but now, after two weeks, still cannot feel much difference.
Not sure whether to ask for my money back like you. Maybe we are expecting too much from the remap.

Re: bmw ecu remapping
In general speaking, Dave is offering money back guarantee for improvement after his version of the ecu tuning. Whether to take this option or not is up to your own decision. (For me, I personally feel that the result is not worth the money that I paid, so I approached Dave for holding to his word on his offer.)
However, I will suggest that you should make your decision, at the soonest.

Re: bmw ecu remapping
I agree. Among all of the engine performance mods that I've done (larger air intake, ignition upgrade/Volks spark plugs/air scoop at Rodney's place [R2D] and the ECU remapping), I feel that the ECU remapping gave the least affect, while all other mods feels improvement on not only right away, but gets better as time passes. (Of course, better engine oil will also feel the pickup and gear shifting response to be better too!)

Re: bmw ecu remapping
Hey guys
After my lack of success with ecu tuning, I decided to give the BMS Powerbox distributed by Boss Motorsports a try as I had read many good reviews of this product by owners who had installed the product. The powerbox is a piggyback system for the BMW N51/N52 motor. It combines 2 products into one - gives real gains in Hp/Torque similar to ECU Remapping, as well as user adjustable Throttle Response similar to other Throttle Booster/TPS (Throttle Position Sensor) modification products.
So I had the Powerbox installed 3 weeks ago and the results have been - wow, this thing really works! Even by butt feel, I can feel a significant increase in power. Car is much quicker now and there is much stronger pulling power from low down and up the rev range. And what is more, my fuel consumption has actually improved. I did not do dyno test but others have done and posted their results on the Boss Motorsports webpage. Typical gains reported are increase of about 25 bhp.
Well worth the cost of $1,200. Unfortunately, works only with the 6-cylinder models so not applicable to 4-pot 320i and 318I.

Re: bmw ecu remapping
anyone knw anywher or any tuner whom can remap 318IS coupe E36? or mayb tune it with UNICHIP Q? haven found any reliable tuner yet..
guys help pls... a little under power leh this car... or mayb not enough power haha
