ProEFI has just released Flex Fuel compatibility for the Pro128 ECU. This strategy allows you to run a flex fuel sensor (available through your ProEFI Dealer) and the computer will automatically compensate for any mix of Ethanol in your tank. The computer automatically adjust ignition timing, boost, and several fueling strategies to properly compensate for the Ethanol content in your fuel tank. Video of the new strategy in action will be posted later this week.
