Enable Open Loop
Posted: 2024 Dec 08, 22:48
I see A1C has the following table and scalar, both of which appear to tell the ECM the TPREL setpoint above which to use OL fueling:
FN311 - OL Threshold TPREL
THBP2 - WOT Threshold
My question is how to get it to use OL above a certain TPREL value? Do I need to set one or the other or both? Right now I have THBP2 set at 550 ad counts and FN311 at all 1024 ad counts and I have no open loop (per my datalog I'm seeing ~700+ on TPREL). Do I need to lower FN311 to 550 ad counts to match THBP2?
