Well, with e85 I watch it to make sure each batch of E85 is not too far off in ethanol content and it will tell me when MN switches back to winter blend.

For the sensor I have "None" and for the units I left blank. If the st + lt is routinely more than about 5ish you should find out why and make changes.

I thought everybody was plotting the stft and the ltft trims together to tune the maf. I have one set up now just using the ltft but it mainly just reads zero, but when im cruising my wideband is reading rich. Im not quite sure why it reads zero, I have the histogram set up right according to what i found over on hp tuners. So either its not reading right or my wideband is reading wrong. Ever since my laptop crashed and I reloaded everything onto a different laptop I can't get the maf histogram to read -5 +5, it will read 0.00. Not sure what I'm doing wrong.

There is a method for tuning the MAF that uses the LTFT and STFT together. It seems like it would work good for the lower portion of the MAF table to me.
