openloop fuel question cruise area
copy of my open loop fuel map.
my observation is a big variation from 60 and 70 load from lower loads and of a big step at 3000 rpm. Is this indicative of odd latencies or a function of the ecu?
And an observation: do not expect the same order of change in the cruise area as in upper load cells. It takes much more input to change the afr than it does in the normal open loop area.
low to mid 15 afr is target in cruise/idle

wooowww.. those values are realy lean 2 hit mid/low 15s. what ive noticed is how you put the ecu in open loop can affect it, whether itis changing the open load tables or throttle position or periphery bit. . i dont know if its just my car or what. ill lean towards odd scaled injectors for out of boost cruising actual afrs seem to center around the target afr. thats what ive seen in my car at lease.
