I must be dumb, because I can't figure out what I am supposed to do to properly calibrate the MAF in ATR.
I did the log as described in the manual...1500 RPM in second, slowly accelerate until MAF exceeds 100 g/sec. Then shift into neutral and go WOT until it exceeds 30 g/sec.
I have the log, but now I don't know what to do with it. I have LTFT and STFT numbers, as well as MAF volts, MAF (g/sec), RPM, etc. I made the chart just like it is shown in the manual.
So what is the next step? I opened up ATR, loaded my map, and looked at the Sensor Cal. Tables section. Guessing MAF table A is for the partial throttle and MAF table B is for WOT? I can't find that anywhere in the help manual, but that's what I guessed. Am I supposed to just use the scale function to make the numbers equal for all the logged MAF voltage points, or only where LTFT and STFT numbers are a bit high/low?
Basically, I can't figure out the next step after getting the log together. I've read through the manual a number of times now, and can't seem to figure it out. I'm sure it's obvious, but the answer is just eluding me right now.
Thank you for any help!
