Code 12 after 2g MAF install with injectors.

[forcefed86]

I'm waiting on a custom eprom chip burnt for the 750's at the moment. But I figured I'd get a head start.

I installed some 750cc injectors and a 2g maf today. I've checked my adapter harness many times over. Plugged in the 1g side of the harness and checked the 2g side pins. Getting proper voltage to all the sensors, good ground, etc. Only throwing a code 12. All the baro sensors etc seem to be working fine. Is this normal?

And yes I've cleared the codes and tried again. Throws a CEL almost immediately. I noticed a resistance check for the 1g MAF in my manual. But I don't have a 2g manual to check my 2g sensor. Anyone know which pins to check resistance on and what that res. value is?

Thanks

Found it. Power wire was intermittent. The pin was misshaped. Bent it back into shape and it works fine, no CEL.

Good job finding the problem, I hate electrical crap. How's it fit btw?

Fit great, I'll post up some pics tomorrow. Yea I won't drive it until I get the chip. But I was idling at 14.5 on the WB02. And it rev'd pretty crisply. I did turn the FP down to 30.

Here's the final fit. Made a little alum bracket for support. Rotated the whole assy. towards the firewall. Then the BOV tube lined up really well, and it helps support the MAF. I don't like the filter adapter. It necks down to 3", seems really restrictive. I'll probably pick up one of the 4" inlet ebay cheapos in the future.

Now I just gotta figure out my idle surge.
