I got my gryphon tonight and immediately went out to hook it up to my truck. When i tried to load the level 1 tune, it wouldnt load it. I left it connected for about 50 minutes and it sat at the screen saying unlocking pcm. I ended up diconnecting it cuz it would have killed my battery if i would have left it for much longer. Anyone have any ideas about what to do?

 

take the negative terminal off the batt for a few minutes....

then put it back on and try again?

 

We've talked on the PHP Forum, and I haven't thought up any better ideas here either. What year is your truck?

its a 97 with a 4.6

 

OK, I'm pretty sure I gave you information that possibly doesn't apply, since I'm not familiar with that model. As Bill said on the PHP forum, call him and he'll walk you through it.
