WOT Open Loop tuning clarification please, few other things.
05 Mustang GT, CAI, muffler delete
I will have my wideband installed this weekend but I am still unclear about WOT Open Loop adjustments and a few other things. Any advice is much appreciated.
When doing WOT pulls will I be logging/adjusting my MAF calibration or does that only matter for closed loop? I have LTFT dialed in to around 2% but my STFT goes positive a lot. I've read this is cool?
What about the MAF failure load, should I be logging and adjusting this table? I have a histogram setup but the values I'm getting back are significantly different than in the tune which makes me think I'm doing something wrong.
When I log my commanded lambda to %error do I make my fueling adjustments in engine-open loop-fuel base map or am I missing something?
I'm also still trying to figure out timing but I haven't really given it too much thought so no questions yet there. Just not really sure where to start. Borderline knock and MBT I reckon. I'd like to get that dialed for 93 octane.
Attached is my tune, a log, and my notes are below:
