1.5. Mounting the controller STAG-4 QBOX

STAG-4 QBOX controller must not be installed in a place exposed to high temperatures and/or damp.

1.6. Selection of pressure regulator

Install the controller according to the layout show in Fig. 1 or Fig. 2. In a sequential injection system, pay attention to select a pressure regulator properly matched to the given car engine power and injector nozzles. A pressure regulator that is poorly matched to the car engine power will not be able to provide sufficient supply of gas at large demand (fully open throttle) and to maintain nominal gas pressure within the system. Should gas pressure drop below some preset low threshold, the controller will automatically switch to petrol.
