Anyone run a flex fuel kit on a G8? I've done tons of flex fuel cars/trucks but I ran into an issue on this one. I pinned pin 40 on the black connector but I can't tell if it's reading right. My normal alcohol pid in my scanner doesn't read this ecm for some reason. So straight alcohol percentage does not show up. I've read some guys scan fuel composition sensor on these and that is reading 0hz. I turned the sensor on in the tune and if the sensor isn't connected or there is an issue you get a 40% alcohol rate and it effects the tune. I'm not getting any issues like that.
