Default WI advice with sti,red,fmic,etc.

I have an 04 sti with utec, fp red, fmic, modified perrin injectors, etc. I have decided to go the wi route using a 50/50 mixture. I want the system where I can turn the wi on or off (have a map without injection and one with to add life to the system since it will not be used except on occassion). I want the system to be activated based on boost. I would think you need more wi at higher rpms but then again there is less load near redline so am open to ideas in this area. I would think I need some tuneability but maybe not since my 816cc injectors would be receiving water injection running idc's of about 60% at 5k and close to 90% at 7k. I use 93 octane and want to probably have a fairly safe map and then an aggressive one for the track.

I would like to use my sti ic tank if possible. SMC was recommended but I just want to learn as much as possible for my particluar needs before I buy.

thanks,

Greg

I am running the cooling mist kit and will soon be connecting my controller to IPAQ for management. I also have multiple maps in my AP. I am not sure, but I think you cannot switch maps as easy with Utech as I can with AP. The coolingmist kit with the controller gives you the advantage to turn the injection kit off if/ when you do not need it.
You might want to speak with your tuner and see what he recommends. You should be able to use the STi tank without a problem.
With the coolingmist kit and controller you can set the sytem to activate at whatever boost pressure you like. I have read that some people connect a toggle switch for activation, however I choose not to.

Hopefully I helped you a little. Im sure some of the other regulars will chime in. Another reason I like coolingmist is for their customer support. If you sell a good product you should give great customer support and they do. Dave is available almost at will.

I definitely want to be able to toggle the system on and off. For daily driving I will not use it. When I do, I would like to turn on the system, prime the pump, switch utec maps and then test it for safety reason. I would think an injector clog light would be helpful but not sure how reliable they are.

I am currently running a UTEC, with my snow performance stage2 kit and safeinjection on my evo. I have a toggle switch to turn the kit on and off and I have 4 maps on the UTEC for different mixtures of methanol. The snow performance kits can be adapted to the sti tank quite easily and will be a very oem looking install. The main things you would need for your setup is a progressive controller (snow performance stage2), a toggle switch and if youw ant added security for your motor you would want some sort of failsafe such as the snow performance safeinjection. There are many kits out there, they all have their different perks, you just have to decide whats most important to you...

What options are out there to save your motor if for some reason an injector gets clogged, the pump fails, wi line comes off, etc.?

There coolingmist offers;

status monitor and clog detector
adjustable controller
and their latest feature is the connection of an IPAQ to help monitor your system

Its great.
Like I mentioned before, you can run pure water and this would allow a tuner to advance boost and timing to get you a little more power.

snow performance has safeinjection which is a controller that monitors flow and when it drops quickly or below a certain psi it triggers a 12v signal that engages a solenoid that causes boost to drop to wastegate pressure...

I use a mbc so I guess that would not help. It would be nice is there was something that worked with utec. Whatever it is, it better work extremely fast cause it only takes a split second to destroy a motor.

It works fine with mbc, www.ultimate-cc.com/SPsafeinjectiondiagram.jpg and the combination of the safeinjection and UTEC make for a awesome failsafe combo, boost is reduced by safeinjection and timing is reduced by the UTEC...

Thanks for the comments, it has been very helpful.

Can the snow performance adjust flow based on maf voltage? If so, that would be great. I run a constant boost from 5k to 7k while idcs go up 50%. I need a system that can adjust flow based on air flow or idc.

edit, never mind I read your thread and it states this is possible.

Thanks,

Greg
