I feel like I take 1 step forward and 2 steps back. Every time I think I understand something about tuning my car, something happens that goes against what I thought I knew.
Can someone give me a good, reliable method for tuning the MAF on the coyote? I've been using STFT as a correction factor and it doesn't seem consistent enough. I have LTFT learning disabled and zeroed out the temp compensation table while logging.
My problem is, I have 3 different drive logs and each one shows lean or rich conditions differently. Log1 showed lean condition of 1.04 in period 187.1. Log2 showed the same period as .98 rich condition and log3 showed the same period as perfect at 1. Is this normal?
These are 6,3, and 9 minutes logs. Are the logs too short to get a good sampling?
I've read about the ABC method to correct the MAF. Is that more reliable?
