    I believe it's necessary to reset SKIM and reset the VIN, then unplug the SKIM module before powering up the PCM. I'm surprised to hear that HPT worked on the 99 XJ. I was under the impression that...

    No, but that would probably work too.

    I can delete SKIM on the older PCMs now. Unfortunately, it wasn't HP tuners that made it possible. And it cost me about 2 grand to make it possible :-(

    I should be able to delete SKIM on all those...

    It appears that the problem with HP Tuners might be their VATS switch only has PWM or Serial as options. Other software has it as 0 = VATS Enabled, 1 = No Light, and 2 = Disabled.

    HPT, this switch...

    How did this turn out? I'm working on a 2011 Camaro, and I don't see any VATS delete option.

    I was successful with the 99 Olds 88. But the security light stays on now.

    I actually used two softwares to do it, because another software had one more rather important looking VATS parameter in...

    Joe, can you list what car it was, and exactly what parameters related to VATS that you changed?

    On no crank, it could be because the vehicle has starter interrupt. So even if you delete VATS, the theft module is not grounding the starter relay, preventing the starter from cranking the engine....

    I have a 99 Olds 88. VATS is set to PWM from the factory. Codes P1626 and P1629 are checked, and P1630 and P1631 are not checked from the factory.

    Do I keep it set to PWM? There isn't a None...

    Just a reminder guys, that when you set injection timing, it's EOIT that you are setting. The BOIT is back-calculated, and would largely depend on how big your injector is. So if you believe that...

    I like it James! I think you're on track. Haven't seen that parameter before, is it one you hacked, or is it in HPT somewhere?

    Is low resolution referring to the cam sensor or the crank sensor?

    I have this PCM on the bench with a constant 13.5v. I've had this issue for some time on 09 - 10 F150 PCMs, and thought it was related to HPT and that PCM. Or possibly to my bench harness pinout. But...

  20. VATS Delete - Let's cover it all in one thread.

    I'm trying to make sure I fully understand everything there is about VATS deletes, so bear with me and please help only if you are 110% sure you know the answers. This one's probably best left to the...

    And for fun, I did a little paint work to show the crank sensor pattern off better. The PCM detects piston position by seeing where the engine is in it's rotation. It's easier for it to determine...

    I still don't know where you're getting these numbers from. We're measuring End of Injection here, not beginning. At WOT, the EOIT is somewhere near BDC on the intake stroke.

    I'm not sure where you're getting your numbers from, but that's not exactly what I said. First off, the stock injector duty cycle that most OEMs are going to shoot for is likely to be 80 to 85%....
