Miller MAF III (Warning: Pic Heavy!)

[var1ant]

I just installed this today and I had the same cel and crappy running issue. Check the connecter to the maf. I Had it on upside down. After that everything ran great

I second that!! I just put one on yesterday and you can accidently put the maf plug on upside down because they didnt machine the maf plug quite right and dont say a damn thing about it... it threw a "1221 code= afm signal".... but once you flip it it should be good. My idle is 650 not 750 like I wanted though. need to call Brody.

I'd like some comparisons between a rebuilt M20 AFM + MarkD chip vs. MAF + Miller Chip.

You guys running stock injectors?

Hey I just installed mine using this guide, idles better than ever at a strong 850 or so, but when you really get on the power, there is a momentary cut-out at about 1600rpm. Do you know what this could be? Thanks!

Old thread but what happens if you go back to stock afm and don't reverse the wires that were spliced on the dme harness?

If you haven't already done this maf. SSSquid makes one that is reversible and easier to install.

I haven't. I had a friend who had this on his car but he put it back to stock , I always wondered if the wiring part had anything to do with the car running lean
