Just picked up a used Gryphon

[ticopowell]

You can unplug the gryphon at any time, as long as the truck is off. To add or change the tunes that are located on the gryphon you should return the truck to stock before unplugging it. It will recognize the gryphon and you will just need to load the new tunes just like you did the first tunes. The tunes are loaded with the truck's internal memory so unplugging the battery will not affect them. Jump starting the truck is ok to do as well as long as the gryphon is unplugged when you do it. Hope that helps

Any transmission trouble you read about is a rare case, it just seems like there are a bunch because people usually only post when there is a problem. Some people also don't take as good care of their truck as they should. That will also add to the thread count.

If you need to disconnect your battery it is safe to do as long as the programmer is unplugged. This protects the programmer from getting damaged during an electrical surge.

The only time you return the truck to stock is when you are going to a dealership (and do it days in advance) or if you are plugging the programmer into the computer.

Ive read the instructions several times and installed my gryphon today. I installed the tranny tune just to get used to the way everything works. I can immediatly feel the difference. It feels much more responsive. I only went around the block to make sure all was ok.

In the instructions, I did not find a section that shows how to return the truck to stock.. what is the proper procedure to do this ??

Thanks guys !! This forum has been really imformative. Even to my dumb newbie questions

When you access the power programming menu again, you'll find there is now a "Return to Stock" selection. (It may have a slightly different name.) Just select it and it will return the PCM to stock. And by the way, to answer a question that's often asked, this is the ONLY way the PCM is returned to stock. Disconnecting the battery or the programmer does not "lose the tune".

I just went out for a test drive. I set ttruck on the tranny tune and tried a 0-60 run to see how it works.

During regular driving. The truck feels really solid and feels torquy.
But while doing the 0-60. I stepped on it hard and it started to like surge looking for a gear then it finally shifted into gear pretty hard. I pulled in to the gas station for some gas and I noticed the unit stayed on when I shut the truck off.
And my unit is stuck on the 0-60 finished test screen. I shut the truck down but the unit stays on.

When the Gryphon screen stays lit after shutdown, it's generally a sign of a failing battery. Please disconnect your Gryphon from the OBDII port (the lit screen will rapidly deplete a weak battery) and have your battery load tested.

When you reconnect, make sure the ignition is ON, before you plug the Gryphon in so that it can boot properly.
