Hello!
Does anyone know something about lotus exige 430, with 2GRFE engine, fuel pump control?
The ecu sends a PWM signal to a control module but is there a specific frequency to make it work?
Regards
Rija

You should just put an oscilloscope on a stock car and figure out what the frequency is.

Yes you are right but the car is 700km away and I do it remotely. I was wondering if someone has already done it and share the information.

is it possible that the pwm is positive signal?
