I've got a weird problem. I attempted to make a cammed tune a week or so ago and realized very quickly that I was in over my head. That was the first tune I loaded on the car with HPT. The car would start and attempt to idle for 4-5 seconds and then die. Then I loaded a copy of the base Roush tune that I pulled off the car with changes for the fuel sys, injectors, axle gear, and tire revs, which should have run fine.
I try to crank the car and it acts like I still have the cammed tune on the car. It runs for a few seconds and dies. I can load a SCT version of the base tune with changes for the injectors, fuel sys and gear/tire and it runs fine. What am I missing?
