IF all of the tuning was done correctly is there a downside to running in open loop?
The way I understand normal EFI operation in a car is: OPEN LOOP for warm up, acceleration and deceleration, and WOT... CLOSED LOOP for idle and cruise (mainly for emmissions).
Is there much downside to running in open loop in a boat? The computer still adjusts for air temp and elevation right?
I don't want o2 sensors in wet exhaust if it is not a MUST HAVE. Thanks.
