He is right the PMS will not work with the LMAF, but I wouldn't say it was limited in changing the fuel curves. It will change +/- 200%. I got sick of all the bad cals and crappy meters out the so i went with a standalone system and now run a map sensor. It is really nice not being at the mercy of a bad meter, although I've heard the new cals are a lot better these days.
