So far I think I get what is being stated here. The numbers in the mgp table will be the difference of the map and the bap. Example of what I think that is saying would be if I am below sea level pressure say 13psi (90kpa) at the map sensor but the bap is at 14.7psi(100kpa), the mgp table would read -1.7psi(-10kpa). Or on the opposing side, if I was in boost at say 18 psi(124kpa)and the bap would still be at 14.7 psi(100kpa) the mgp table would read 3.3 psi(24kpa)
Is that correct?
So how do I adjust to tune this?
I personally have done extensive research on learning how to tune and now I am attempting to put what I have learned into practice and this is quite the curveball. I haven’t learned anything about this until now and there doesn’t seem to be a lot about this. Everybody that talks about it on the internets refers back to this thread. What are the equations? I have built an extensive excel table to assist in calculating fuel delivery and injector pulse width using MAP as the load axis. HP Acedemy, the platform I am using to learn how to tune doesn’t really address this method of calculation. How do adjustments to this table effect my AFR?
