I have just installed an apexi avcr electronic boost controller.
However when I turned my ignition on, the unit did not light up. I checked the wiring again and this is definately wired correctly.. I checked the power going into the unit and that is there, I also checked both earths and again they are ok.
Dya reckon it is a faulty unit or is there is something I could have missed?

Also with the apexi wired up, the check engine light comes on is this correct? (original boost solenoid is disconnected at this stage)

 

i fitted a blitz boost controller to a 1998 impreza and the ecu light didnt come on.

i would say the was a fault with the unit or you aint used the correct wirring diagram. try just supplying power to it with non of the other wires connected .

 

yeah have tried it with just the power and earths connected but still apperars to be no power in the unit.
