I am not sure if all MAF s are calibrated for the same voltage. The datalog would be nice.

the analog never shows it going above the set point.

I can try to get a datalog on here but I won't make any promises.

i know mine was havin problems, i closed the maf loop back to stock for a while, it worked perfectly after i did that.

Well I took all of your guys advice about it blowing out spark because it's too rich. I tested my maf sensor againist another msp maf sensor. Guess what? Mines contaminated.

I replaced the maf sensor. After that all my readings were different than before. I backed some fuel out and now it runs like a champ.

(wiggle) Glad to hear that this issue is resolved.

Any idea's on how/why it was messed up? Good to hear things are going good now.

It only takes alittle bit of dirt in or touching the wire to really screw up the airflow meter. Mine probably got contaminated during one of the many times I've had the airbox out. The long and short term fuel trims were off by 8% which isn't enough to throw a code but damn close.

Here's a word doc I typed up, I hope it helps. I did not go into full detail because it's not needed. This should help, if you want to know what the unit does in more detail, you need to look at the manual.

I can't say enough how much I love this document!!!!

Thank you, thank you , thank you!!!!!!!!!!!

I owe you a lot of beers for that little document!!!!
