Hello. My Greddy turbo timer has been on my car for a while now but suddenly stopped working. From what I've checked everything appears to be hooked up ok. The only thing that appears to function is the on/off button.

I took a picture of the screen to show what it displays. Does anyone know what this means or had a similar issue? Any help would be greatly appreciated. Thank you

 

I have no clue on that. I would try to unplug it and see if you can reset it.

 

Yea I tried. Still nothing Thanks though
