Hello,
I'm new to ECU tuning. Normally I tune with distributors and Weber carbs on vintage cars.
As here several times explained I tested with the scanner the MAF and made a histogram with MAF-STFT.
I drove at different engine revs and loads and moved the throttle slowly.
The cells on the MAF-STFT histogramm shows values between -52; -50; -49
What does this say to me as I was told that the value should be close zero. The MAF settings are stock.
