Question since I'm not as electric savvy as most! 5 volt pullup source connect to Ecu 5 volt output Negative Pwm (-) Pulse signal to from Ecu Where can I tap into for positive and negative? This is on a C7 Z06 Thanks in advance
Any way you can trade it in for a programmer where you can increase the pedal sensitivity without having to use 5V? On my Diablo, the programmer increased the throttle tip in by 30% in the program without the foolers.
I dread tapping into any of the reference voltage stuff on the car. Since I could get it to do what was needed without having to put another thing in line to cause problems, why not? Is returning it an option?
OP: What are you using this circuit for? Controlling boost on the stock SC or an aftermarket SC/Turbo? Are you trying to use the stock bypass boost control signal from the ECU? As others have mentioned I would be leary about choosing just any 5V reference voltage coming from the ECU without knowing whether or not this added circuit is going to overload the circuit and cause problems with other controls using the reference. The description of how your controller works leaves a lot to the imagination. For instance, is it going to be to be using the PWM signal to pull down this 5V reference or is the 5V reference being used to power the circuit?
This is what the stock boost control circuit looks like:
Description of how it works:
Depending on how the PWM Negative signal is connected inside your module using the stock ECU bypass switched ground as the PWM Neg source might affect the 5V reference tied to the orange lead. I can't see you using anything but the stock ECU boost control circuit because any other PWM-Neg signals will be related to non-boost functions and not really programmable to be used to control boost.
