Re: HFS-4 Q&A, application for your engine...
It is not a problem. we can re-configured the controller to take the 3.5 bar map sensor or 5 bar map sensor, just need you to return the board to me. Unless you are planning to run 36psi, the 3-bar map sensor configuration on your current circuit biard is just as good.
See page 21. All factory setting is for 0-5V absolute sensor. The blue wire can be used for other sensors such as MAF, TPS, etc.
