Devilsown Methanol Alcohol Water Injection - View Single Post

Alright I think the calc is a bit off, and it doesnt state what the gph flow is for. It said I needed a 8.4gph nozzle but right now Im running a little over 10gph and in the next few days here moving to a 15gph nozzle injected right before the throttle body.

In the tune I do pull quite a bit of fuel out and my AFRs are right around 12.0:1 timing is around 9 degrees at peak tq and ramps to 27 degrees at the rev limit, with about 1-2 knock counts which is acceptable to the ECU. The meth starts injecting around 16psi and is at full flow at 24psi.

Im wondering if I lower the "on" time to generate more lower end tq but will go through my 1.5gallons in no time.
