Hi, I have just installed the above boost controller.
It workes fine in 'OFF' mode (Standard boost) and i can get throught the whole rev range of the car but as soon as i choose a aftermarket setting and hit anything above atmospheric pressure, the car coughs, the hicas light flashes and it feels like it dies. Switch it back to 'OFF' and it boosts no problem.
The boost is set using a range of 0 - 100. when i set it to 0. I can boost with no problems (as 0 is standard) but once you go up a touch, like to say 5, it doesnt like it.
(For the pressure signal to the controller, I tapped into the line that goes from the fuel press reg to the manifold.)
Any suggestions?
