Default It's really not much of a headache

Bosch Motronic tuning is proving to be very stable when using the XEDE as an interceptor/signal generator/boost controller. Accounting for throttle by wire, adaptation/learning, boost limits, etc,. doesn't appear to be much of a problem. At least with Porsche stuff. I don't see Audi being much different. I'll tackle it upon return from One Lap of America.

FWIW,with a mildly modded 993tt, we picked up 40whp@5000RPM and 120whp@6500rpm over a remapped ECU. Real easy. Only took 8 dyno pulls to do it. It would be nice to see things work out half as smoothly with the Audi. We'll see...

Thanks again for the info guys.

Regards,
shiv
