I loaded my 87 tune and went to custom to check tire size. when the list appeared I went to hit the down key but hit enter in error. I now have a message that indicates ERROR F1 vehicle calitration not yet supported. The message won't go away, the evo will not shut down and i don't know how to fix it and am afraid to move the truck????

Try programming again. But for this time follow this procedure:
1. Leave the ignition key in the ON position.
2. Disconnect the Gryphon at the OBDII port.
3. Plug the Gryphon back into the OBDII port.
4. After getting to the main screen, wait 15 seconds for needed parameters to be loaded.
