controlling a water metahnol injection setup

[Craigorypeck]

Who has done this with a MJ?

I want to bring on water/meth injection pump at around 2500 rpm, so using a shift light should work ok. but I only want it to operate when I have boost so it doesn't work on deceleration.

I presume i would need an external boost switch wired in as the MJ doesn't have boost switch capabilities, or does it?

Is there any way to control a progressive water injection system with MJ?
I could use the remaining shift lights to open more valve nozzles as the revs increase (to 8k) to add extra water/meth but this would be a lot of wiring and piping with reliability issues.

Is there a 0-5v output from the MJ that can be setup to ramp alongside engine revs? Most progressive meth injection systems utilize a 0-5v signal to control pump flow voltage.

Thanks!

You can certainly control a user output based on the load setting. Check the operation guide on how to do that.

Let us know how it goes!
