How's it going everyone, I picked up a 92 hatch with a ca18det. The PO or whoever did the swap was a little out there. It was running a Central 20 chip with an SAFC and it ran poorly. So im having a local-ish tuner make me a chip with his new software. I ordered a second chip that would get here quicker to hold me over. Anyway, the car would not rev past 2500 with the new chip, so I removed the safc and reatached pin 26 (green/black) to the ecu for the 5v maf signal. Now the car should run fine with this chip but is throwing code 12, I know my maf is good, i drove the day before the new chip. So I tried my second maf and a third maf all N62's, which is what the chip is coded for. Nothing seems to work, I rewired the maf about 4 times today, i even took the wires directly from the maf to the ecu and still the same problem. The car wont idle, wont rev past 2400, and has giant fuel clouds exiting the exhaust.
----When I changed to the new chip I noticed that there are 2 jumpers on the ecu board. Ill post a pic, any input on this would be greatly appreciated.
Also, key one, the maf 5v signal gets 1.5 volts and the 12 volt power gets well just under 12 volts, so wiring is correct.
I'm lost!
Thanks everyone!
