I pondered for a while what numbers i'd get with the CTSC and tuning for meth. At the end, I tuned for without meth and simply used it for cooling. I was driving the car pretty hard at the time. I didn't want to succumb to any one failure point. I also wanted the ability to simply put water in there in a pinch. With that said.. In the 5yrs or so I was on that setup it never once failed AFAIK. Also, my AFRs didn't change materially to require a retune. IIRC it added about 0.5-1 AFR of richness in the tune at WOT under prolonged sprayage (i.e. a long track day session)
Noted on the plate. Definitely sounds like the dream. I really want low air temps on demand. Having to have it sort of primed and using so much is not ideal. I’d love to be able to spray a little meth and get the octane boost but not have it hugely affect the AFR.
I emailed AS Motorsport about it and asked a bunch of questions. We’ll see if he’s down to make one for me
Man I really want a fully ecu controlled solution. The data alongside the rest of the engine data, plus the ability to precisely set it up would be amazing. When I eventually move to a haltech I’ll make an attempt to have it run the system in a nice way. Though I still haven’t seen anyone with a simple ecu-only setup. The pump requires a lot of current. So it’d probably be a PWM out to the dumb AEM box.
