I've got a snow performance 2 stage water meth setup in my car
Can I put a 12v signal into mvpi so I can log when each stage kicks in or will it damage the unit if I do ????

The interface only accepts 0-5v inputs. Are you using a progressive controller or just an on-off switch to toggle your injection?

HPT only recognizes 0-5V. Whether it'll fry something if you try to go higher, I have no idea. I wouldn't try it.
Was just a brain fart lol
I will leave it be
You could run the 12V signal into a micro-relay as the trigger, and then have the signal/feed side send 5V (from an underhood 5V source) to the MPVI. That is assuming you have any unused 5V sources available. Alternatively you could use a pressure transducer(s) inline that accepts 12+V in, and puts out a 1-5V signal(s). These are the ones I use to log my fuel pressure: http://www.motorsportsinnovations.co...B_Pressure.htm Part Number: WB-762
Otherwise you are SOL and stuck using resistors as previously suggested.

The Honeywell PX2 line of pressure sensors have served me well, even with meth.. I've never had one go out. They have about every combination of thread, pressure range and output type that you can come up with, and they're about $70... Personally I just put one of those on my meth system, gave it a 5V in from one of the coils and ran the 0-5V out back to HPT and called it a day. Has worked fine for well over a year.
Post a log and tune if you want help
