    Reviving an old thread... because it's my thread and I finally found the answer:

    You must ground pins 32 and 34 on the 0411 C1 connector to tell the ECU that the truck is in park/neutral (even...

    The computer should still read it, even with the engine off and the key on. Maybe a bad wire? Maybe check continuity from the ecu connector to the TPS connector.

    What did you "switch" from another working truck?

    Have you tried checking to see if it even has power to the TPS? Or if the pin for TPS feedback is in the correct spot?

    Are you worried at all about fuel economy or is your truck strictly a tower?

    Quick update on this. The reason why I could not CASE relearn was due to the RPM limits I had for VSS failure and P/N.

    They MUST be at least:
    VSS Fail- 5,600rpm Resume- 5,550
    PN- 5,600 resume-...

    So, theoretically could I have jumped the rotor a tooth so the cam offset would be near zero when the dizzy was in a serviceable position? Then everything would've been fine?

    Well, some progress. I was not able to do a crank relearn, BUT, with the offset being -50 I was able to turn the dizzy to get it to -3.

    I'm now able to get more than 27? out of it. Still bucking a...

    I think I had an issue with torque management keeping me from upshifting properly. After going through the TM tables and maxxing/zero'ing out all the tables I could.

    I am needing an extra pair of eyes to figure out why I am not getting any spark advance past 27deg. I've only recently noticed this change, and it looks like it may have started after I changed my...

    Yeah, that bog is likely throttle cracker. I modified my table, but not yours. I thought it was brought on by my headers or ignition. Looks like I was wrong.

    I requested from him when I got my initial tune that he turn down PE to "zero" but as-in allow it to come on. He basically said "You don't do that." It is rather dangerous if the VE and MAF are not...
