I am having a 2002 Subaru WRX built up that will NOT be running the stock computer or MAF sensor. The current plan is to have the engine run off a MegaSquirt ECU.
Since I am unable to use your sequential system, I am wondering about the feasibility of using the stage 1 universal kit and two nozzles triggered by two pressure switches at different set points.
The lower
pressure switch setting could power the pump flowing to the first nozzle and the higher set switch could control the flow on and off via a 12V solenoid valve to a second injector.
Thoughts?
