Article on Snow Performance and J&S Safeguard Integration for a safety net

The December issue of MM&FF includes an article titled "Safety First".  This is a technical article to show how to safely utilize the Snow Performance methanol injection system to allow additional timing in a tune. In the past damage could happen to the motor if you added the timing and for some reason, lost the methanol flow. Suddenly you found yourself in a detonation condition and we all know what that means.

 We added the Snow Performance Safe Injection flow sensing module. This unit is tubed into the Meth line and will send out a 12vdc signal when the flow falls below an adjustable set point. Normally this is used to light a warning lamp, but we all know that isn't something that we can react quickly enough to to save a motor. What we did is also install a J&S Safeguard system to do something quickly with this failure signal.

The J&S Safeguard can control the spark advance in the motor by adding Dwell to the spark. It is attached to the control wire of each coilpack. It has an auxiliary 12vdc input that when energized, adds dwell/subtracts timing immediately. This originally was intended for a nitrous retard, but works very well to pull timing on meth flow failure. The J&S also adds its main function in life, which is to sense detonation and remove timing should anything else cause detonation to occur. This is done with the input of a Bosch know sensor you can purchase with the unit or the existing Ford knock sensor if your car came with one. It works extremely well in my experiments. A great investment in keeping your expensive motor in one piece.

Please checkout the magazine article and I also have additional pictures of the J&S unit and it's install in an additional article on this site.

Thanks!! to Steve Baur of MM&FF, Matt Snow of Snow Performance and John Pizzuto of J&S for all the help on this article. They are great people and have great products. Also for Tony Gonyon for the donation of his shop and dyno time.
