And for those of us that would you can follow the instructions I written sometime ago. It works very well and if you have the AEM I strongly recommend using it, the pressure switch is already on top of the SMC pump so you just use its switching source voltage. If you don't have a pressure switch you can purchase and intergrate one to be used the same way.

Spray too early and itll bog your car down (kind of like hydrolock all depends on how much you're spraying with what nozzle). Find out how many CC's you're spraying first off (you'll need to know how many psi your pump is flowing), how much boost are you planning on running? Sometimes its a game to figure out what size nozzle to run. For example..

My eclipse *in sig* runs a stock 7bolt motor with 272s/headstuds/headgasket with a fp3065. I tuned it at 27psi on 93octane at 11.5a/f. Once I started spraying 100% meth through an M15 nozzle (6" off the throttle body -sufficient enough to fully atomize the meth at 100psi pump pressure) a/f's dipped into the 10's. I had the option to either up the boost & lean it out or just lean it out. I chose to stick with 27psi and lean it out. I leaned it out to 11.5:1 and increased timing till the point of knock (I tune for less than 2degrees of timing being pulled and EGT's under 900degree celcius). Some cars run stronger with some counts of knock, others -not. You need to see what works the best for you. HTH..

oh btw, I went through a dual stage meth kit *dyi*, with two pretty large injectors, then tried smaller, tried one big one small..and ended up running NICELY with full spool (27psi) at 4100rpms with the meth starting to spray at 13psi. MY car loves the m15 nozzle @ 100psi pump pressure.


ps. a ROUGH estimate to figure out how many CC's your injector is flowing is to set the pump pressure to 100psi, and install the injector -just not in the intake tract and spray into a volume container, spray for a minute and read . I did the math...and m15@100psi pump pressure is roughly 660cc..

 

I don't know anything at all about the Autronic EMS.

For the AEM EMS with SMC alcohol kit Buschur Racing wires it into the AEM EMS so that when the alcohol injection pump pressure is high it switches to the alternate fuel enrichment and timing control normally used for N2O.

BUMP for more input....come on guy's...tuners!!

THANKS

 

Jason,

It's quite simple. Call me and I will explain :-)

You lost my number?

 

LOL...i'll call both of you
