Greddy profec B spec 2 display issue.
can anyone help please.. I downloaded the manual and installed the boost controller . When I turn the key on it comes on just fine and I can go through the functions. But once I turn the car on I get just a blue light and no parameter display. I can scroll the knob and it makes sound, also makes sound with the select and mode button but I cant see anything. I turn the car off and i can see everything fine again. Anyone ???
