Ok So I'm trying to figure out what is going on with my redtop but I'm really starting to get pissed. This morning I start the car on the tune I had made last night and it ran ok but I had to turn up the injector latency to have it run a little better. So it idles good all morning and I start checking sensors, using my volt meter I check TPS, MAF, CAS (2.5 and .67 while running) and Nistune confirms all voltages are reading the same at the ecu...
Then about 2.5 hours after running the car my timing starts going crazy. I had it set at 15 and then nistune starts reading 15-5-9 and I have to keep reving the car to keep it runing. Not to mention its WAAAYYYYY to lean.
I pull a bad CAS code. But I replaced the CAS and just checked the voltages (2.5V and .65V while running) and I seen the same voltage at the ecu. Pulled valve cover off and timing is dead on. No matter what I set the timing to it just around like crazy. there isny at SR guys around here so I can just swap out ecus or any other parts for that matter.
I disconnected the MAF and it went straight to rich condition (10)
I'm wondering if I'm not having a problem in my harness or ecu.
