Dealer reflashed PCM i got ???'s

way2qk4u2c · #1 Thu, May 21st, 2009, 09:17 AM

Ok i took the truck into the dealer for some routine repairs under warranty...before it went in i reflashed my pcm back to stock using the gryphon. The dealer flashed my pcm for one of my problems so now my question is.

Will my gryphon work as normal or do i have ot have Bill change the hex code or anything?

Im assuming itll work fine....but i want to make sure before i plug it back in.

It depends - Turn on the ignition key and plug your Gryphon back in. Note your HEX code! If it is different and it probably will be, there are two options:

If you do not have your custom tunes yet, you should be fine. You should be able to reprogram the truck to any of the canned tunes. But, make sure Bill and Corey get the new hex value so that your custom tunes can be written properly! Change it in your UserCP too.

But, if you already have custom tunes and the HEX code is different, then they either won't work properly on your truck or you won't be able to program the PCM at all. Contact Bill so that he can modify your tunes, which you will have to "re-download". In the meantime you can drive around on Level 0 and use the unit as a gauge. (Bill should be able to "fix" your tunes rather quickly, once he knows your HEX).

If the dealer reflashed your PCM and your HEX is no longer TEJF3PZ, then the files you have will not work.

Incidentally, I had already made adjustments to the OD issue you were having and loaded them on the server but if the HEX is changed then those updates are useless.

Let me know what the new code is.

So basically under no circumstances the dealer should never be allowed to re-flash your pcm if you have custom tunes.

Not unless you have a good reason for doing it, such as addressing some sort of drivability issue or something like that.

AND, PHP sells these cool little plug covers that say, "DO NOT REFLASH - Or I'll cut your ...."

No, they really don't go that far, but, they do sell the "Don't Reflash" covers. Might be good insurance - especially if you have a recent model year truck.

No problem. I'll get everything converted over to the new HEX.

Take care.
