Correct me if I'm wrong, but I understand the ECM will calculate fuel first from the Fuel -> Open Loop -> EQ Ratio table, and then under PE (in my case 75kpa and 50% torque minimum), it will apply the Fuel -> Power Enrich -> EQ Ratio multiplier. But that EQ Ratio multiplier is only a function of RPM, so once you enter PE, can you only adjust the fuel adder based on RPM?
Ideally, I'd like to control fuel (and spark, too) with not just RPM, but also MAF, so I know when the cylinder has the largest charge.
