I am running COS5 2bar SOLSD at the moment working on getting the VE tables dialed in with a safe tune. The most boost I've run so far is 9.5psi at which I'm about 10.8-11 AFR and ~14 deg of timing, I'm running on 91 pump gas but assuming I'm getting E10 out of the pump.

Once everything is dialed in, I'd like to start spraying methanol/water while adding timing and AFR. I will be spraying a 33/67 or 50/50 mix of meth/water at 15.5gph with dual nozzles. How should I go about adjusting the tune for the methanol? My plan is to have a street boost setting of 5-7psi w/o injection, and then a spirited boost setting of 12-15psi w/ injection. I'll be using my boost controller to turn on the injection at probably around 8psi or so.

One idea I had was to use the nitrous trigger in COS5 to modify the fueling when injection is on. Anyone do this?

I'd like to think of the meth/water injection as a safety net since this is my daily driver, it will never see the track.

Thanks!
