Ian Seppanen Posted June 7, 2012 Report Share Posted June 7, 2012 Im back with a new problem.Â I got the setup issues figured out, and got a base map set up on the ECU.Â I put around 200 miles on the car breaking it in, and suddenly I began having this problem. When the engine reaches full operating temperature, signal 2 begins to get flaky, and as everything in the engine bay heat soaks I lose the signal completely. Once the engine is allowed to cool down, everything goes back to normal, and the car runs fine, until it heats up again. The first time this happened, my wiring harness was still temporary.Â Most butt connectors and the like.Â Since I had gotten everything working I assumed that the cheesy wiring was not transmitting the signal.Â I pulled the wiring harness out of the car and finalized everything.Â Solder, heat shrink tubing, then wire loom, and tape to seal everything off.Â I put it back in the car, and epic fail.Â It still dies out once hot.Â My trigger wires are shielded, and the only place they run alongside the wiring for the coil is at the firewall, and the foot to the ECU. Is this an EMI issue?Â Or should I start looking at problems with the Cam/Crank sensor built into the distributer? Specs on the car are 1991 Nissan 240SX KA24DE with factory ignition, and trigger setup. Custom wire harness. Thanks for your help guys.Â I have a race in 3 weeks, so I would really like to get this sorted. Quote Link to comment Share on other sites More sharing options...
