Hi guys,

  I haven't really been on this forum for a long time , or really touched my B5 S4 since Daz passed away   I knew him for about 5 years online and he helped me out with tuning my B5 S4. As a lot of you know he was the most awesome, funny, selfless guy I have ever known.
  Daz had tuned my car for 98RON petrol (Im in Australia) and E85. Currently its running e85, Daz wanted me to switch back to 98RON and have a another look at a log file, then he was going to make a switchable file for both maps via the cruise control.  I really have no idea whats involved in this, and was wondering if you guys can help me out in setting this up?
