I've been reading into water/methanol injection just out of interest (I don't have the money to get it at the moment).
I gather the progressive controller can work by communicating with either the MAP or MAF sensor, or by plugging into a vac source.... I was just curious as to how it works with the MAP/MAF sensors? As in will it tell the pump to kick in at a certain pressure pre TB or with a certain air flow in the MAF??
