Just wondering if someone could shed some light on the smartshield Enagine Enable Signal which goes to pin four of the ecu, My understanding is that it is PWM with varying duty cycles. Unfortunatley I dont have a car with legit smartlock or I would just scope the signal myself. Reason I ask is I am going to make my own bypass module with one of my avr's so any technical info or even a scope readout would be awesome, Also if you are going to say buy one please don't as I dont want too pay for a glorified square wave generator same as I didnt pay 80 bucks for a 2 dollar voltage divider err I mean shift kit
