i was wondering if the EGC o2 simulator will work on simulating o2 for the primary sensor. i know that people use it to emulate o2 on OBD2 cars when runnint test pipes etc. but i needed to know if it'll work on the primary one. thanks.

Why would you want to? Basically it works by sending a false signal to the computer to make it think the converter is working right. If you send the computer a false signal on the primary sensor, it won't know how to adjust the mixture. I can't think of any good reason to want to do that other than creative ways to screw up the motor.
