I got the truck back and tried loading a custom tune and when I tried to edit the tire size I recieved an error message that siad the calibration is not compatible and it gave me error code F1 and told me to phone the Vendor (PHP)The gryphon still functions normally and displays everything it should but now it won't accept the new tire size and I'm scared to try and let it just do the custom tune without adjusting tire size because I need the truck for work and don't want it to disable the vehicle or something. I also could not clear the error and had to unplug the unit in order to get the display back. I tried plugging the unit into Pegasus and found that it has a calibration update (version 1.02.0613) but when I click the update button it tells me it's going to clear my custom tunes so respectfully declined....lol

Help when you can guys no rush as the truck is still drivable but not nearly as fun!

First, you done good bypassing the "Calibration" update. That WOULD have wiped out your custom tunes!

This is from the Gryphon manual though (when in doubt, RTFM!): "ERROR CODE 0xF1 (IN CUSTOM MENU) – If you are receiving this error code while trying to configure your custom options, disconnect from the OBDII connector, turn the key to the ON position, and plug the Gryphon™ back in. After getting to the main screen (past Intro and Disclaimer), wait 15 seconds. This will give your unit time to load parameters it needs to perform the custom changes. You should now be able to perform your custom changes.

Hopefully, this will get you going again. However, here's the way I'd really do it: With the key ON, plug the Gryphon in. Then, try to load a tune but completely bypass the Custom Options menu! Just click on [No]. If the tune loads, all is well - the dealer flash did not change your hex code. If the tune does NOT load though, Bill is going to have to rebuild your tunes for the new hex code the dealer's flash must have created, and you'll have to get it to him. It won't take him long to do this, but he can't do it without the hex code.

If the tune did load though, go back and reload the custom tune you just loaded, but this time say Yes to the Custom Options menu. Verify and correct (if necessary) your Gear Ratio and Tire Size. And, make any other changes you want. Scroll to "Done" and hit [Enter]. You should be good to go.

Let us know how this all works out, please?
