You can also check out CoolingMist .They have a new Vari-Cool Coolingmist Controller. It is progressive and works off of a boost source rather than the MAP sensor although you can control it from the MAF or MAP signal if you wish. I think you should be able to run it without going to the 2 bar MAP tune that you need to do for the Alky Control system. Naturally it is not in stock but they hope to have it by the end of February. Check out the Forum for a better description of how it can be connected.
The Alky Control system works off of the MAP. So you need to replace the MAP with a 2 bar MAP for up to 15 lbs of boost or a 3 bar for up to 30 PSI of boost. I am assuming that you need to adjust your tune for the 2 bar MAP to run Julio's system. Can someone confirm this?

 

Devils Own Alky kit , there progressive controller works killer , im useing it with a GM 2 bar map sensor and it works like a champ . They have a great price and very good support also . They answered everyone of my emails quickly when i had questions about there kit .
I had to have my PCM retuned for the 2 bar map .

Ordering one of the Alky Control ones this week. Heard nothing but good things about it.

 

That looks like a good basic progressive controller but not nearly as tunable as the AlkyControl PAC Progressive Alcohol Controller. It just depends on what your goals are and if you require the utmost in reliability. Not everyone needs all the features of the AlkyControl.
