Unhappy Redtop SR20DET only idles with MAF unplugged.

I recently swapped a redtop into my 91 240sx hatch. Everything went great until I tried to start it, with everything hooked up, it will start, maybe idle for 1 to 2 seconds and then bog down and bounce around 200rpms and slowly die. When I unplug the MAF the car idles fine but as expected will not rev above 2k rpms. I have checked the maf plug with a multimeter, I get constant 12v on B, ground on C, and .05v on D (all readings froms the harness side). I have swapped the CAS with known working, timing is also good, I used a known working MAF (it is in my coupe that is also SR swapped). I put my ECU in a friends car that is also a redtop in which his car started, ran, and idled fine. I checked for fuel and I'm definitely getting it. I'm running out of ideas here and haven't been able to find anyone with the same issue under the same circumstances, any help insight would be greatly appreciaited
