    I got a nelsons tune.....this one is the 2nd one--the 1st shifted too hard. This tune shifts perfectly.

    I STILL can not get the crank angle learned---Allen suspected it was a bad pcm---this one is doing the same thing.

    We are using a Mac Mentor to attempt the learn. The 1st one was attempted with the mentor and a Tech II.

    What's the deal guys? has anyone had this problem? The Mac Mentor goes through the steps, tells you to rev past 4k --does not learn.

    We tried to clear the code, it set itself immediately back, I also tried to clear the code with the engine not running and it still comes right back on.

    I'm thinking there is a software problem?

    I had the CS relearn issue w/ the my very first (and so far only) tune from Allen, and also have an '04 Silverado. Had a local shop preform the relearn procedure, i think using a Tech II (not 100% sure). In my case it took about 5 seconds to clear once the engine was revved.

    I'm wandering if it can ONLY be done with a tech II? The first time I tried it was with a tech II and with the mentor---both did not work.

    I'm about to come unglued here....

    That's interesting. This is purely conjecture on my part, but maybe the scanning tool itself has to have the latest software/firmware updates to handle it. For example, the tool's sw version would work fine w/ an 03' PCM, but would need to be updated for an 04' PCM?

    LOL Well that blows my theory. Anyone else got any guesses?

    Yea--It turned out to be an old software on the Tech II's. Once I updated one of the Tech II's it worked fine.
