My question is who has hooked up meth injection to an Fcon?
Exactly how did you do it? By what method did you control the injection via the Fcon?

There is more than one way to do it. I would just like to know from thoes who have already done it.

I'll be doing this NA. I am using a cooling mist kit with a high speed valve for variable injection duty cycle.

I also have the cooling mist control box but I would rather have injection directly controlled from the Fcon.

Ask these fellows, I think they did a GREAT job. The have the VPRO automatically swictch map when not on Meth.

So to revive an old thread. Just put on my meth kit. I'm using a 400cc nozzle with 50/50 MeOH/Water

The pump turns on at 9psi (about 5100 rpms) as controlled by my UTEC and verified by a green LED i have on the dash.

I've read from Snow that you should see a 0.5 to 1 point richer AF once it sprays (which is any point 5100 rpms there should be noticable drop in AF). I'm barely seeing any richer AF.

Both runs were done on the exact same map, the only difference being meth being meth vs no meth.

According to Snow, my tune should be leaner before I start spraying, but the relative drop in AF should be the same.

So whats the deal, bigger nozzle?????

I wish my UTI software could access the dashboard, then I could log IAT.

Utec IAT temp will be off since the Intake Temp Prove is by the MAF sensor. The only way you will see a drop of temp is if you are spraying before the MAF Sensor. If you are not seeing any drop on A/F then by Snow's instruction then you are not spraying enough and vice versa. One thing I don't like about the Snow kit is that you have to keep changing the nozzle to get the right amount, does your Snow kit has a Tune **** that you can increase flow without changing the nozzle like the Coolingmist/AIS kit? I have read the Snow Instruction and you are right about the expected drop to .5-1 A/F and if you are out of that range then you have to change the nozzle to the right one.

ya its pretty much the basic kit. on or off. I'll look into the 600cc nozzle and try again i guess.

One thing to consider is that are you sure your are using a 50/50 mix? The A/F drop is directly related to how much Meth is in the mix.

Yup, one of the perks working in Pharma research.

well i ordered a 600cc nozzle and wil try that.

what nozzle are other people using??

There is a screw on the black regulator housing on the pump. Turn it clockwise about 2-3 turns to increase the pressure of the pump. It can go up to 200psi. Try that first before switching nozzles and see if the AF richens up. You should be seeing at least a .5 A/F drop with a 50/50 mix on that nozzle size.

Btw, did you happen to take dyno's before and after the injection? How much did the 50/50 mix add?

Thanks.

i just heard about this water-meth kit and im curious if its worth it with the little upgrades i have, and how much does instillation usually cost?(or is this something i could do by myself.. im no good at installing parts) i was looking at getting the stage 2 and im wondering what kind of gains i could expect..

you can gain alot of HP if you tune for it by advancing the timing. i'm not changing the timing, just using it to richen my AF so i can lean back the injectors. Also to make sure i dont knock retard. Meth kits are basically race gas only when you need it, instead of spending 5$/gallon for race gas that you only need 20% of the time.

I have the Snow kit on my car . I start the pump and spray at 7psi which is 1/3 of the total boost and ramp up the spray all the way to redline and 20 to 22psi of boost . This is from the Snow instructions

do you know how big of a nozzle you are using? I assume you saw a minimum of 0.5 richer AF when you started your tune?

If I remember right its the 400 nozzle . And yes...I saw a 1 point richer A/F

I know what water/meth injection is but that is about it. I was over at the Snow Performance site looking over thier kits and its all german to me. What I gathered is I would need thier Stage 2 MAF Boost Cooler kit. Mind sharing a bit more insite on this subject for me.

Thanks!!!

this is probably a dumb question(if its like my usual question in the mods section) but with the few mods i have is it worth it to get it and to advance my timing? how do i go about doing that? and any down sides?
