Ok, i know that means it is in limp mode or safety mode as some call it. Ill start with the known problems. I have no maf, i know this would cause that symptom. I have the ca18det harness and ecu. The gauges do not work and the check engine light flashs when running and the brake light is on( on the dash lights). I have 3 maf, stock ca18det, z32, and q45. There is no connector on the wire harness for any of them. I dont know if they are good or not. I cant find any test values for them. The stock ca harness has 5 wires for the maf. I know ppl have done the z32 swap and i tried on mine, but same problems. I got the car in this way and knew it was gonna be a project, doesnt bother me.

So, my thoughts are to just make my own harness or buy a new one from other 240sx cars or swaps. I also was wondering if going with a speed density or map sensor would be a possibility, that way i dont have to deal with putting a maf on it.
