Hi
does anyone know how can I know flex fuel sensor actual working on AEM tuner software
because My tuner said the car keep rich on pump gas even adjust fuel rate so EMS think E85 injected in engine
I have SOS flex fuel sensor kit and this kit is PNP kit so I double checked and its all hook up correctly

if you see the flexfuel tap, you will see the flexfuel blend percentage section
does this section read E85 percentage rate real time and showing?
my car is sticked on 99 percent

thanks

 

I'm sorry but i'm not a tuner so i cant help you. But i do have a fuel fuel sensor and a flex fuel tune on my aem sieris 2 and it have been working amazing for well over a year. the more ethonol in the tank the ecu will automatically raise boost/timing and change fuel trims.
