Crazy ECU Codes!
Hi,
As you know I just finished my MPFI swap and I still have problems. Its drivable but barely, you dont wanna go to far with it. (or fast) Anyways I counted the number of blinks on my ECU and heres what I got: 1: Oxygen Content 4: Crank Angle Sensor 5: MAP Sensor 6: Coolant temp 7: Throttle Angle 10: Intake Air Temp 12: Exhaust Gas Recirculation System 13: Atmospeheric Pressure 15: Ignition Output Signal I know there are alot of codes, the good thing is it starts right up and idles decently. Please help, I gotta get this car outta my garage. Thanks Alot.

dude u must have really messed up on your wiring, or theres alot of shit bad on the mpfi parts u got or your ecu is bad.
did u try and pull hte hazard fuse and see what codes u are getting, just to make sure its not codes that were already on the ecu. try reset it

Check your MAP Sensor and your O2 sensor. If those are both good, it's probably your wiring, 'cause I think both of those will throw the majority of the codes.

its weird taht u are getting a code 15 ignition output but it still starts up and runs fine. u should try run another ecu. because usually a code 15 if everything is hoooked up correctly is your ignitor, u wont get any spark if your ignitor is bad
