Why in the first place did you decide that it was a GOOD idea to try and update the firmware?
Did you get......
An email?
A notice?
A phone call?
There has been NO updates for the Gryphon firmware since December 1st 2008.
The only thing that changes is the Pegasus versions.
For anyone else reading this, unless PHP contacts you and tells you to update the firmware, don't do it. Unless you're selling it.
This updating proceedure is something that other tuners companies need their customers to perform due to their software/firmware. The Gryphon firmware has been pretty solid with no changes needed.
If you have custom tunes you have the best already.
Peace!
