Maf Tuning Question

[pitcrew207]

Well i have an LPM, and i know it came outa a X2J computer.. well heres the question, Say the LPM was programmed for a Upgraded MAF, i plug the chip in with the stock MAF... What would happen? cause right when i plugged it in i get a low idle then it jumps back and forth, but after a few weeks or so its pretty normal idle sometimes its jumpy.. any help would be nice..
thanks
Joe

As evidenced by the bouncing idle you have described, your EEC is being confused by the signal it is receiving from your factory MAF and the aftermarket curve that it's being fed by the LPM, and until your EEC has been reprogrammed with the proper MAF curve, it will continue to be confused and your engine will not run optimally as a result.

If it were me, I would have the LPM reprogrammed to account for the correct (factory) MAF setup.
