OK.. So I have A3 2.0 TFSI. I would really like to have REVO stage 1 map (or equivalent)... I have previously had some experience with Revo on my S3 and TT, but with both had to use an SPS controller to change from the standard map to Stage 1/2/3 etc.. This involves mucking around turning the ignition on and off (not really ideal when MR M3 nob 'ead is taking off next to you) lol Anyway I wondered if there is any way of having a button so you can change the map "live" whilst driving?? Please help!
