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.
