swapped maf out ecu light come on swapped back still on and wont crank

[240drfter]

had a p60 maf on rb25det ran ok not great (sourcing the right maf out)

been driving for like 2 weeks or so. had a n62 maf i wanted to try out to see if it ran better with it or not. so i hooked up the 62 started up but went into limp mode ( idled but rev limited with any throttle). so i figured no big deal i'll just put the one i was running back on. put it back on and know nothing happens. just turns over.

the ecu lights stays on (idk if it was on before or if it needs to be on or not)

tried to find out about the screw on the ecu didn't find anything but one guy already had asked but no responses. is the screw how you get the ecu to throw codes

just wondering if anybody has run into this or not. i know it has something to do with me swapping out mafs. ran fine before now won't even hit at all.

like the ecu just cut off

today i had some time to start diagnosis and first thing i did was unplug the maf altogether....car fired right up. does this mean that the maf that i had on there was bad.

does anybody know the ohms so i can check it (p60)

If it's a series one rb25 buy a J60 Mafs actually I have one I can sell you if you want.

thanks i know that i need a j60 i don't have one right now. i'm trying to figure out why my car won't crank. i've been messing with it for a few hours now and it will crank up every time W/O a maf hooked up but as soon as i hook up either of my maf sensors it won't fire at all....by the way how much for that maf

[240drfter]

does anybody know a resistance test i can do to check the maf at the ecu....

how many ohms between such and such

The mafs you can have for 60$ if your interested
