Was out of the game for about 13 years until recently. Was looking thru stored stuff and found an ATR 7th injector I'd forgotten about (never used it, must have bought it used early on). Also have and old SMC with pump in bottle that I cannibalized for controller and float. I also just learned that E85 can be 51-93%. I have sensor and SD2, and wasn't planning on alky but all this got synapses firing and thought about using SMC controller and 7th injector size for baseline flow and ATR for proportional control since it is piggybacked off of main injectors.
Upsides would be SD2 could implement overboost/max rpm/? control. Should be truly proportional. Fun to do.
Downsides are how 7th injector will distribute alky as it comes out thru a 9/64" or so hole from vacuum block area (it replaces same). Also I believe it is based on just 1 injector's "signal", so not sure if that matters. Also what about running injector with no fuel for short periods if it relies on it for cooling. I could control arming it at same time as SMC, but would want to have its trigger boost lower than SMC starting point for in car control. Probably other stuff I am forgetting or haven't thought of yet.
Thanks for reading. Feedback welcome, except that of the "Why not just buy a proven kit..." variety. I already know that's what a "normal" person would do!
