Ok so I recently put a 2g maf in my 1g, used the stock 2g pipe and recirced my BOV.

Everything works fine, EXCEPT... at very light throttle positions I get MAF signal spikes, the MAF freq spikes up to 3000+ (according to the SAFC). This causes it to spike the injectors and the car nose dives from being so rich.


I figured it was a bad MAF at first so I swapped to a known good one last night and same problem. After reading the VFAQ some more the air flow reset makes alot of sense since it happens right around where my idle switch kicks in. I'm not really sure what to do to resolve this other than clipping the idle switch wire to the 2g maf (Pin 7 on the MAF). Also not sure why I'm the only one that has apparently ran into this (searched everywhere).

Here's a pic of the issue on my logger

It's resolved, the wiring was fine... it was all the dump tube length in conjunction with the BOV being open at 17-18 inches of mercury. Which I solved by crushing my BOV :D.
