New map, reset ECU and still check engine light

Evolunchbox · 07-23-2007, 08:55 AM

I posted about this earlier and I did everything I was told to do. I was throwing misfire codes since I installed the PROcede at high RPM's and it was going into limp mode. I installed the 1.47 LBT Map and I don't hit limp mode any longer but the check engine light is still on. I then removed my negative terminal for a couple minutes and that still didn't clear the light. I even used my code reader like it's instructions said and it wouldn't remove the code.

What do I do now? After all of that I started the car and the light is still on. The car didn't moved an inch and the 0306,0305,0300 still come up. Suggestions? All help is greatly appreciated.

Thanks!

I had the same group of error codes come up and when I opened my covers I found the connection for the #7 wire had slightly pulled apart under the tape.

Is the car off but ignition on when you try to use the code reader? That is the only way to clear the codes.

White Loom maybe?

THAT WORKED!! Thanks!

I'll have to take it for a highway run to see if it stays off but that did work!

Yeah, should throw that in the instructions that the c-reader can clear your codes...

Very funny!
No, thankfully my Evo is OBD1 now using an AEM. Stock ECU's on Evo's don't tend to favor 700+WHP

I see you have a quick Evo as well! The combo of these cars completes me

Yeah, I know that you have an AEM, but I still had to bust your chops

Your car made unbelievable power at Buschur. I remember the thread where you both were raving about it. The Evo is fun, but I think I might let it go here soon. We'll see.
