Hello
Recently, I installed an AFE cold air intake.
Truck runs still great, but I discovered that the fuel economy gauge in the dashboard alternate more than before.
Watching the numbers with the VCM scanner told me that the LTFT en STFT are on average 10% positive (sometimes even 40% in total)
So I guess, with the larger diameter of the air intake, the ecm miscalculate the air mass....
I decided to recalibrate the MAF table...
I don't have much experience wit HP Tuners , but I went this way:
Disabled the dynamic (high rpm to 0)
Disabled DFCO (Disable ECT hyst to 256?C)
Disable COT
Disable LTFT (Min ECT to 256?C)
I made a table to log the MAF frequency against the STFT
Problem is, when I start logging, the MAF frequency stays in the 0hz cel.... (Because i get no value for the MAF frequency)
Is there someone who knows what I'm overlooking?
I added the log file
grtz, D
