Our Vari-cool kits have a nice option to work with Utec. This can be our standard Varicool or our S-HSV kits You can set varicool 2 work in 2-D mode with UTEC and boost. For example, you can set the min and max boost on Vari-Cool to activate when a UTEC signal tells it to. This works great if you have some condition you would like the injection to activate that the UTEC can compensate for.

Any kit will work with the UTEC. I would recommend any of the progressive kits. I ran (and several of my buddies run) the SMC kit, and it works wonderfully.

I now have the coolingmist varicool trunk mount because the 07 FXT doesnt have anyplace under the hood to mount the SMC. It looks like a quality setup as well, with the same capabilities in the controller (more if you want to use the MAP for the signal)

I personally dont recommend using the UTEC to activate the progressive kits out there because why bother? They all work just fine by themselves and you have to make the exact same changes to your maps in the utec that you would have to regardless of what turns it on. Why complicate things more than they need to be?

The Utec has a separate PWM channel for driving a comparable inline valve to a fuel injector. You can use the utec to drive our 2c, 2d or HFS-5. The mentioned system has a coil impedance very similar inductance to the fuel injector coil. 2d and HFS-s has in-built failsafe. The utec can control them with a separate map.

If the utec has a spare anaologue input, it can monitor the flow of all the system mentioned as a failsafe mechanism.

I don't think the utec can drive a "pump-speed type" progressive system. I believe the inductance and the current drain of the pump is too much for the output transistor of the Utec.

To clarify with our kit if you use the UTEC as an activation mode the varicool will PWM the pump. If you use our S-HSV kit with the UTEC the Varicool will PWM the high speed valves instead of the pump.

Eitherway will be very cost effective and give you great performance.

To learn about our S-HSV kits you can click here, there is a FAQ
