Help my Gryphon does NOT work

[mmandley]

So i got my Gryphon today and i was all excited, i read the book with it front to back over a coffee of course.

I went and installed it in my truck and turned the key on. Then plugged the tuner in and it powered up.

got my Hex code. TEJF1Q6

Set my screen up like i like it then went to Menu

Select performance

I selected 2 87 Tow tune

Turned the key off.
Turned the key on when prompted.

D2 error. Truck wont accept info from the tuner.

I retried several times and tried all three tunes and always got the same D2 error. I went into Tech Support and did a communication test and it passed.

Then i redid all the setting and started the truck up and drove it around and the display works and i get all the readings im asking for but it wont load any tune at all.
