I am currently trying to work out a breaking up problem and a super rich off-throttle situation.

When I go full throttle in the turboxs map, the car will accelerate from low RPM to about 3000RPM, but after that its like a soft limiter or a 2-step kicks in, its really weird. I have the #1 pin on the connector grounded so I dont think thats problem. Also the car accelerates fine in the ("0") stock map or any unchanged map. Any thoughts? Im going to make sure my parameters are 100% right before I get into more serious diagnosing.

Another thing is a really strange problem. It happens in every map. When I let off the gas and let the engine brake, as soon as the revs drop to approx. 1750RPM or lower I start getting a lot of popping and backfires out the exhaust. It smells like the car is going VERY rich and that is the cause of the backfiring, but I dont really understand why the UTEC would cause me to go super lean. I have taken the UTEC out and confirmed it doesnt do this with only the stock harness and ECU. Any thoughts on this part either?

 

So, it looks like the cutting out start at 2000 rpm, which is exactly where the UTEC takes control of the timing. could this be a problem with the ckps wire or what? Remember it runs fine, accelerates fine in the "0" map

 

I also just found that in the dashboard the UTEC displays the current timing (while running) to be 0 degrees so im guessing that its not reading the timing right? Do i need to connect both the ckps (pos) and ckps (ref)? I only see one pin for the ckps in the pinout (pin 95 for 5.5gen), is there another? Or do I need to connect the cam position sensors to the UTEC?

 

I'm 90% sure the cam position sensor was connected for my install.
