Hey guys, bought vr4 not running and as I am making progress on getting it back up and going, I am planning ahead for some future things. One question I have is, what kind of signal does the stock boost gauge get? I know that ECMLink can be used to change the gauge other things besides boost, like knock count. From reading, it is my understanding that the 6 LEDs cannot be split up to show 2 different things and so I assume it can only have one input signal. So, does it operate off of a 0-1v signal? I have tried searching and it appears as if the only returns that I get are people saying that its a terrible boost gauge. Thanks! |

5v signal but controlled by a scale encoded in ecu. |

gotcha, thanks! I was wondering how exactly it functioned |

Is there any way to test this boost gauge? I want to use this in my EU Galant, but i dont find many informations about this thing. There is one wire missing from my ECU connector (PIN3 Turbo Gauge), but are there other things what i need to change? Thanks |

supply max 5V to corresponding meter panel for the boost gauge. if you have a variable resistor, use it to regulate the 5v signal to check each boost gauge LED. |

Thank you. I will try that. I use Pin 23 from the ecu (maf Supply 5V). EDIT I tried it and all led‘s are working;) thx |
