Question for Tony

Tony,

Have you tuned any cars with a pmas or pro-m meter? If so do you take the calibration sheet they provide and put that in the maf transfer table or is there more to it than that?

Yes, I have. And yes you put the cal sheet info in. You will more then likely still have to tweak the curve to be perfect. You can do the lower range using the Short fuel trims (if you have good o2s) and do the upper end with a wideband.

ok, thanks the sheet from Pro-m only has 9 data points and a maf transfer table has 30 points correct? I plotted it in excel and fitted a line to it to get the equation then extrapolated to get 0-5v range. The sheet they provided only went to 3.5 volts or something like that. Oh yeah the O2 sensors are brand new so hopefully we can get it dialed in correctly.

I haven't had to convert the 9 to 30 points, so I just looked it up on SCT's site. Most of the dealers say it is not worth trying to convert it and use it. Just use adjust the curve thats there.
