There are failsafes, failsafes and failsafes...

the failsafe is built into the controller and you will need to replace your controller to utilize it.
it will be able to work with older smc kits.
steve is going to come up with some sort of deal for people that already have v2 controllers, to get a v3 controller
there is NO ETA on the v3's anymore. steve can't keep up regular demands at the moment, let alone developing a new piece.

Our Safe Injection option is an additional controller that measures actual fluid flow. If it drops below a preset level, due to no fluid, clogged (complete or partial) injector, pump output failing, etc. it will trigger the 12vdc output. This can be used any way you see fit to bleed boost and/or pull timing.
It won't account for a loose/leaking connection *after* the Safe Injection, but I am not sure how to do that feasably - always open to suggestions, of course.

May be it is a good time for me to collate a more indepth study on the merit of each failsafe system available, it has been sometime ago since I started this thread.
Good to have WI makers to contribute to this thread.
Making good power is one thing, but coping with a "loss of injection" is just as important. .......edited.......

Some devilsown controller safe guards.
Full time current sensing, this will warn you with the fault light to get out of the gas by flashing the 3rd LED.
The controller will go into fault mode if
- excessive current draw (clogged nozzle)
- fault in the pump circuit (dead pump)
- controller overheat (internal saftey)
- pump wired incorrectly (user error)
- loss of pump ground wire (low level sensor add on)
Control set up to put in test switch just by adding a toggle
The 3rd LED will flash and the controller will go into fault mode for any of these issues.
The cheapest and best way to monitor your system is simply adding a snubbed pressure guage period. It's right in your face and is accurate just like your boost pressure gauge. Un snubbed guages will have violent pulsing to them and will not give you a true reading of actual pump output pressure.
Clogged nozzle (pressure will not drop when the pump is off)
Pump wired incorrectly (will show the pump cut on and off with pressure drops)
Pump failure (no pressure)
Hope that helps out for you DIY guys.

I have the SMC kit on my car and have had it now for about 6 months. I think the system is a time bomb. I had a hose come lose and it did not inject for a 2nd gear pull. Then I had it knock a little but that was due to tuning. I am going to be removing this kit and doing a pump and race gas map on my new motor with a gt35r. I think my motor is okay but this is a quick fix and something will fail after time. The system is okay nothing great and to do a great system it will cost several thousand and then it is still not safe. Want to make good power spend the cash for race gas or just run pump and know the car is not going to blow up and you can sleep at night. To the SMC guy that says we worry too much, how about if a motor blows do to your system failing you pay 100% of it?

Again the safest way is just to run the race gas. When I am tracking my car at Road Atlanta the last thing I want to worry about is some 1/2 assed injection setup or that I pull a high G load and it starves the pump or some other BS. I dont want to save a few $$ to blow up a 10k evo race motor. Remember you can pay now or pay later, I want to pay now you will pay later

Its not a half *** Ace Hardware brass fitting hack together, but a well thought of and engineered system. Pricey yes but worth every cent not mentioning the peace of mind using it.

Its a pity a badly designed injection system has steered you away from WAI.....barb fitting + hose clamps, you are right *tick tick tick* a time bomb waiting to go off
