Vipec ECU (http://www.vi-pec.com/) has MatCorr(MAT,TPS) table.
I think it is better than airden corr or simple MAT table (w/out tps) and good in tuning.
Aslo i have made more precise scale for MAT corr: Corr = {((Value + 280)/4)-100}. So (0)=-30%, (255)=33.75% and step 0.25%
TPS axis is a small cheat, it has same scale as boost vs tps table
Q: Does firmwares still contain universal gas law based correction? Does this table is as additional correction? Or is it the only MAT correction factor for fuel calculations? MembersPage/GintsK
A: Only table correction applied, MAT correction from hex file dropped, fill table manually with airden curve, and see MT aircorr gauge and MT log, it show final (interpolated) correction.
Q: This must be clearly written in firmware changes. I just load 1.1.41 for bench test. Base value for table is 100 in this firmware. Why fake air density still affects? What method you recommend for reasonably tuning? MembersPage/GintsK
