I am seriously considering getting this unit, and since you are pretty much the "pioneer" for the J&S and finding info on it and working for our cars, i was gonna ask a few questions... :-) is there anything else other than a knock sensor that we will need to get for it to work on our cars? im certain it wires into the factory ECU, know which wires it uses? thanks for any help, either post here or email me at NitrousEclipse97@aol.com thanks for any info man.

Here is a link to the Subaru instructions, as it will be nearly identical in hookup to what our cars would need. http://www.jandssafeguard.com/SubaruInstall.html With the J&S, you will need to buy a knock sensor, i believe a GM type, and a bolt adapter of some sorts, totalling around 575 bucks, all of which can be bought at J&S. This unit will also have a user adjustable knob for inside the car for boost retard amount. If you would like to have the car go into open loop at any other psi than 0, John, the designer, can program several dipswitch settings for set boost amounts, like 5 psi, 7 psi, ect to go into open loop. www.jandssafeguard.com

not sure what it is so...what is open loop? pros/cons? thanks
