Ok so heres the story, I have a 96 del sol with a 99 h22a swap. Car was running great for me untill recently. Driving home one night car threw a CEL and died on me wouldnt stay running no matter how much gas I gave it would just sputter down i pulled the code it was a solid CEL code 0, I was running a chipped P72 with Uberdata so thought the chip might be bad or something. I pulled the chip and inspected it looked fine so i put it back in no change. I pulled the backup fuse to get ride of the CEL and the car started and ran fine again drove it home and didnt give it much thought. Next day on my way to work same thing solid CEL after about 20 mins of driving, I kept keying on and off and eventually the code went away and the car ran fine. At this point I figured I had a bad ECU so I converted a PR4 and upgraded to Neptue RTP for tunning duty while I was at it. Car was starting and running fine untill tonight while I was out tunning and got a solid CEL again. The only thing that changed on the car between the time it ran good and the Solid CEL was me Installing a new head unit. If anyone has any info on this it would be so greatly appericated im at a total loss I dont even really know where to start.

It could be in the settings of neptune. Have you thought putting a ecu witihout uber, netptune, ect and see if it throws a code and what it is?

I sent the ECU to Chris at Xenocron had him inspect it, checked out fine. Same program ive been running for over a year so I dont think thats it. Im really looking for electrical issues that can cause a Solid CEL other than a bad ECU. Thanks for the reply though any and all ideas are welcome im about ready to burn the bitch if i cant get it going.

You try grounding out that wire to make sure the CEL function is working correctly? (i think you called today)

Hope you get it sorted...
