By reprogramming the ECU, we were able to increase power for the Audi RS4 by an astounding 26hp & 26lbs tq (over stock) to the wheels. No physical alterations were made. Once the vehicle is reprogrammed, power is widely available throughout the rpm band, all flatspots/hesitation are smoothed out, and speed limiter is removed. By pressing the “S” button, instead of the valves opening at 3-4k rpm, you have the option of either permanently leaving the valves open or leaving it as is, stock. According to many RS4 owners, the notchy shifting (1st to 2nd) commonly claimed has been cured by the tune.

Please inquire about any Audi model.

Please contact the sales department for any questions or concerns.

Please obey all traffic laws. ECU Tuning Group does no encourage speeding.

 

considering you're quoting 26hp over audi's advertised hp rating, did you come to this conclusion using an engine dyno?

do you have any actual dyno gaphs?

 

All files are created and tested using a Cartec dyno.

As of the moment, we do not have any dyno graphs. I'll search around and post one up as soon as I find one.

 

so its a chassis dyno, but youre quoting engine hp.. sorry for the twenty questions, i have a rs4 and wondering where i should go for a tune. just trying to figure out where you are getting your numbers from.

 

Numbers quoted above are to the wheels. My apologies, should have clarified.

 

so what else was done to that rs4 to give you a baseline of 420whp?

 

Seems like there is much of a confusion. Gains originally posted above (26hp 26lbs tq) are to the wheels. My apologies for tacking those numbers to the baseline to give you a completely incorrect end result. Thanks for the heads up jjm

now that that has been cleared up... dyno sheet to prove said gain?

 

LOL what????? A tune fixing a mechanical transmission issue... yeah okay

 

At first I was weary of this company, but after my research I decided to pull the trigger. Almost four years later and I cannot be any happier. In fact what the OP said was true. The tune really does make a huge difference in 1st to 2nd gear shifts. It's not fully fixed, but it's a whole lot better. You will be just as surprised as I was, guaranteed.

 

yea gonna call bs on this. makes no sense. tune might change tq curve or something that masks whatever notchy shifting issue you might have, but the tune couldnt physically fix a mechanical issue.


OP- dyno sheet will go a long way here.

 

Please forgive me for saying this, but neither do we have any dyno sheets available nor do we have the time to back track and search for one. However, the next time a customer walks in, we will be more than happy to dyno their vehicle for the rest of the public to see. We are currently working on up and coming cars like the McLaren MP4-12C, BMW M5, etc. We finished the RS4 almost 6 years ago, it's a very old car to us and we just don't have the time. Once again, we apologize. We urge you to check out our competitors who can provide you with the necessary information to make a sound decision.

 

no apologies needed. if its 'an old platform" for you, that you cant back up with the bare minimum of proof (ie a simple dyno sheet) then move on to the mclaren and bmw.... hopefully youll have dyno sheets for those guys

 

any timed acceleration runs to back up these (very bold) claims?
