Thread: :(Might not make it to the sr20 convention..need help

Ok, I installed a Calum ecu programmed for 370cc,z32 maf,4bar this is for a b13 w/ a u13 motor. The car was stock and running fine back in oct. before I blew the transmission. The Only mod was a walbro 255 and a intake and the u13 motor. I decided to throw on a z32maf and new calum ecu. OK problems. The motor did not rev past 2k rpm if i pushed it, the most 4k rpm. I recheck the wire diagrams. Voltage coming out the maf was around 3.74volts at idle. Now the motor won't kick over and the plugs where fouled.I swapped the plugs, and the motor still won't turn over. Check the plugs again and i didn't smell no fuel. I adjusted the fuel pressure to 58-59 vac off. (this is when the car was idling). I doubled checked the ecu harness and its fully plugged in..Now im stumped, IM about to pick up a new Maf and swap it out to see if it makes a difference .. any other ideas?

double check your wiring and ground, if its not right it wont run, the two middle wires on the z32 plug are ground, thin wire is 5v positive, thicker wire is 12v, if you have them backwards it wont run right and will be in limp mode and might not even start at all.

Again double check the wiring, its very possible you got it wrong. For one 3.7 volts at idle is way way high so thats why im guessing you have something wrong.

Where in Jersey are you?

SRSLY. Where in Jersey are you? I can stop by tomorrow to help you sort it out depending on location.

Definitely MAF wiring issue, hopefully you didn't do any damage to the ECU.

I swapped the maf and still no good. Im from Elizabeth, 13a off the turnpike. Im thinking its the ecu. The car started again and i lowered the fuel back down and it idle better. Do you guys have a spare stock maf with the wires?

whats the 2 voltages you get from the maf

help him so he can go to the convention!!!!

either wiring or ecu issue, most likely wiring.....someone helo this man quick!

WOW, my old and motor still running. That **** is a beast man. I'm sure it has about 100,000 boosted miles on it and still kickin. I hope you get things sorted out Andrew. If you were closer I'd be the first to help you. Good luck.

I don't have a MAF with clipped wiring harness with me. Everything's at home in TX.
