So the way we get around is by scaling the MAF to reduce fuel trims? Does not look like the most straightforward approach to me. Maybe this is the only way to get fuel trims right until someone discovers a table or something that should be changed that will make the ECU adjust fuel pulsewidths appropriately when PFI/DI ratio is changed.
