Actual Vs. Commanded Lambda Lag in 1st Gen Coyote, Help
Hey all,
I have a Coyote Swapped SN95 using the control pack, car is primarily drag raced. Its a 2013 F-150 motor with Mustang Intake Cams, Swap LTs, Full exhaust, and JLT CAI. I have an issue that I cant seem to figure out where the car takes a really long time for the actual lambda to reach commanded lambda after a gear change (stays lean for a long time). Also, it needs positive STFT's to reach commanded no matter what I do to the MAF transfer. I have tried increasing values in the MAF transfer repeatedly and the load will go up but it doesn't appear to change what the fueling does at all at WOT. Enrichment Rate is maxed out a 1.000. What am I missing? Attached is my tune and a Log of the car at the drag strip. At about 00:01:01 into the log is when I leave the starting line.
