At the very least, nothing. Everything still seemed to work normally with the benefit of a (not very accurate) over speed warning.What effect does the Audi radar cruise tweak have?
I did this and noticed a pretty significant increase in throttle response. I was quite impressed when I got on on my short journey to my first stop... and then realized that I had left the OBDeleven in and my JB4 wasn't running! It was even better when I swapped everything out on the next drive after I got that extra boost back.
The tweak definitely removes the time variable from the R throttle's time and percentage throttle logic. Definitely more linear like my old Subaru LGT.
