Revo Technik - ECU Tuning & Engine Management Software

Doing APR Flash 3/29. Like some of the features like it leaving an exact stock copy on your ECU. Not getting their dyno chart but I plan on dynoing after I have it done. Will bring car to same shop where I had dyno'ed last fall and posted results here, Car has Stasis and EVO Filters so will be able to see if APR gives any additional gains

Got the APR flash done today. Car felt like it had more torque but could not give it a good test since it's pouring out. Hoping to get to dyno later this week to compare to the results I got last fall. Will post the before and after results. Also they don't have all the programs available yet so I just did the 93 octane for now since thats all I run in my car, Will be able to go in and get rest for free when available.

At our Audi Club track event last week, I won a raffle for a discount on a GIAC chip tune. GIAC does the chip tuning for VF Engineering's supercharger, but they don't yet have a normally aspirated tune available for the R8. According to the company they are "working on it". If I end up going this route, I'll report back on this forum.

Finally dried out here so was able to get a good ride in to see how I liked the APR. I don't know much technical stuff but all I can say is I find a decent size difference, Car just seems so much more aggressive and fun and it's snapping my head back when I really hit it. Also put the booster back on and no problem using with the flash. Within the next week I'm hoping to go back and dyno on the same one I did last fall for a comparison.

Hi RS4 - at what rpm do you start to feel the difference? do you feel more torque around 2500 to 3500 rpm?

I do feel more there but it's 4k-5k where it seems to give a larger boost

Thanks RS4.

Ok, we have the following ECU options:

1. APR
2. APS
3. Stasis
4. Revo

So, which one is the best??
