Im confused to what the differences are between the 2. Im gonna be running either a 100 or 150 wet shot on a m6 bolt on car. What would be the better one to have?

 

they are one and the same...the "window" is the RPM range you want the nitrous to be used. 3000 RPM - 6000 RPM is a common window used. you can get digital window switches or pill style window switches.

www.msdignition.com/rpm_7.htm for the pill style switch

www.msdignition.com/rpm_10.htm for the pills

www.msdignition.com/rpm_14.htm for the digital switch

digital will cost you less money...they both do the same thing

 

Actually they are not the same. The RPM Activated switch merely gives power to the circuit and turns it on, while the Window Switch turns the circuit on and then turns it off as you reach the installed rpm pill.

Yaaa dont buy that rpm Bull$hit stick with the tried and true Msd window switch. i have the rpm p.o.s, and i would steer very very clear of this switch, there are no pills to set ( u are relying on the stupid switch's stock programming!), and it also doesnt hit till 3,600 instead of 3k and it doesnt ever shut off it will go till u lift off the accelerator. again its a P.O.S and u cant set ur shift points.
