Thank You brother!!! Saturday night I added a little E85 to my street car (with flex sensor) and barely made it home, the car stalled just as I pulled into the driveway. I had all those unnecessary adder/modifier tables enabled it fouled the plugs. Changed spark plugs, watched your video, edited tune. Sunday AM: Spanked 2 sport bikes! Woo Hoo!!!
Another good video . I still need to add a flex fuel sensor to my combo . I’ve just got mine tuned for ethanol and swap tunes for gasoline . Definitely not ideal
the reason you can run leaner on ethanol is because of how the Bosch O2 sensor calculates the AFR. It actually calculates in lambda, and on your configuration of the holley software you likely have your base fuel set as pump gas not e85, if the e85 base fuel was selected the lambda would convert to an e85 AFR instead of a gas AFR. ie the actual stoich afr of e85 is 9.8 or so but that would read as 1.00 lambda. so it reads in your afr table as a leaner value even though it is still a richer value than what it would be on gas. you don't need to know all this which is awesome but i think it is helpful and cool to know and understand.
Do some research on lambda….wideband sensors read lambda where stoich of any fuel is 1 which is converted in the ecu to an afr….itll help you better understand why you can run a leaner ratio with ethanol
Great little introduction to Flex, thanks!

@MrGtilton dude that's awesome to hear!

Good video, easy to follow!
Awesome video! After I listen to it another 5 times maybe I can put those Wild Rides torque boxes to good use 😂

@chaskacox-potter3217 thanks for sharing, I'm really intrigued by this! What would an appropriate e85 afr be?
When can we expect a carb tuning video?🤔
Just waiting for a carb truck that runs and we'll do it 😁
