Does anyone know if the signal expected is;
0 volts = 0% ethanol
1 volt = 20% ethanol
2 volts = 40% ethanol
3 volts = 60% ethanol
4 volts = 80% ethanol

Just tested pin 6 and found it had 12 volts on it. Also the wire on pin6 runs across to pin 20 on the fuel pump power control module.
So I don?t think this is right.
Should be a PWM signal, not voltage. Gen4 stuff is as followsOriginally Posted by stingray22
50 Hz = 0% eth
51 Hz = 1% eth
149 Hz = 99% eth
150 Hz = 100% eth
The telltale sign will be on the Flex Fuel tab, is a default frequency listed?

Flex Fuel on the C8s doesn't go to the ECU Pins.
Same with the trucks?
So far I've seen it's just with vehicles running the Global E99. So the C8s & Eray, the CT5Vs, the CT4Vs, and the Escalade V.
For global B vehicles (cars) it doesn?t pin into the ecu. Even once pinned you have to modify the actual code to enable it. We can do this for you as well. I dont get on here often but feel free to find me on Fb or IG
