I have a stock GT went 12.7@110 with my 305/35/20 MT. The best I was able to mange was 1.90 60' and I tried every launch technique. Apparently the DR was not able to help me much. Therefore, I would agree that the auto needs a converter.
Didn't know our ecu was this complicated. Given the information you just mention about calculating area. Then yes a tuner would def need to know physics and math to understand how the edu calculates throttle opening.
So someone def need to brush up on y=(fx) or area under the curve.:doh:
