Z32 maf issues with s14 ka24det

[Schoelkopf94]

Hey guys,
I just finished my kat build and I am stumped. I am running at 11 afr up to 12 when reved.

Jwt ecu tuned for z32 maf and 370cc injectors

My maf has 10-12 volts on all three wires. I checked the wiring about 13 times now. Everything checks out according to jwts guide. I also bought a brand new maf and the voltages are the same.
No continuity across the maf terminals except the two grounds. Nothing looks burnt on the inside. I also opened the ecu and didn't see anything burnt.

I can not figure out what is happening. Pls help. Can I check the ecu in a different way? Does anyone know how to check the maf outside of the car and what the resistances should be across the terminals?

Do you have a link to how jwt wants you to set it up? When you disconnect the MaF, do you still have 12v at the wires?

No I don't. I followed JWTs guide for the maf wiring but the ecu was purchased used. I called jwt and talked with a tech and he believes there is an issue with my harness. I will be looking into that tomorrow

Also, no when the maf is unplugged I only get 12v on the proper wire. I will also be bench testing my mafs because that fact alone tells me the maf is bad, just hard to believe two behave exactly the same.

If u have on 1 wire with 12v going in....and its pluged into the maf and now 3 wires have 12v comen out..maf is shot.

After testing continuity in the harness and bench testing both of my mafs, I've decided to buy another maf. Harness was good but both mafs showed incorrect resistances across the signal terminal and power terminal. Hope that was all it was.
