Hi All, I had my 2009 s4 avant MRC'd on Friday, as far as I can tell there were no issues with the mapping and the car made 473ps so relatively healthy.. The issue comes with the way the gearbox now behaves. At a high rpm gear change pre-mapping the exhaust would make a noticeable 'farting' sort of sound, this has now completely disappeared. When accelerating WOT from a standstill the car is now slower off the line up till about 3k rpm in first gear when it then exceeds previous performance. I have tried this with ASR completely off in S mode. Another interesting thing to note is that when in D with ASR on the car short shifted in 1st @ 4k RPM which it has never previously done (a feature of the new mapping I assume?). I haven't tried launch control as I assumed the car didn't have it as it is early 2009? Will it now be enabled with the s tronic map or is my car too old? I will try this when I get an opportunity. At very low rpm's in D mode the car now seams to almost struggle more like its holding onto a higher gear for longer, for example it may stay in 2nd gear until almost stationary and if I then accelerate lightly it is slightly hesitant. I didn't notice this before mapping, has anyone else experienced this? (it is subtle). Just looking for some insight from someone with a mapped car who may be able to answer some of these questions. Thanks.
