When asking for technical help at the very least let us know the version of firmware you are running.Cliff's Calibration (Mapping) Guide is a MUST READ: http://www.vemssupport.com/forum/index.php/topic,97.0.html
Having one of the faster cars out there, I hope you understand I can't simply share logs of the car. Had to work hard to get where we are.Besides the offsets in boost target, it seems I'm now seeing changes in timing as well.Please help me understand what corrections are causing the spark advance to go to 22.5deg instead of the 19.2deg interpolated from the spark table. Let me know.... I'll try to provide as much data as possible.

I know my way around VEMS!
You can see from the calculated model that I had 19.2deg of timing dialed in my spark table, but the ECU spark advance is 22.5deg (3.3deg more than I dialed in) with none of the corrections or trims being active.Anybody have an idea where the difference comes from?
