Ive just connected up my Greddy Profec 2 Boost controller and I have power going into it (12v) , but no display ?

I have tried holding the set-up button for 2 secs, but still nothing ?

Have I missed somthing or is the unit broken ?

 

have you checked if there is an ignition feed wire to it mate? constant 12v may be the keep alive memory but may need a trigger 12v when ignition on to power it up

 

Its ignition feed fed already
