Summary of change:
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 http://www.vems.hu/files/MembersPage/Andrey/MatTable.JPG 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 A: Yes, 100%based used, because MT has some problems with negative values. Check config.airden_ignore = 0, it is still in firmware, and make same correction as earlier at idle, but MT config not fixed for new resolution (i forgot because never use it), simple make it zero to disable.
