This tune update is for blending together existing tunes you have done with us for pump gas and E85 or ethanol blends. You MUST have already purchased both pump gas tuning and ethanol tuning from us in the past to use this option. Ethanol tuning means a full E85 map or at least an E50 Blend map. We will create a new flex fuel tune for you and blend your existing two tune files together into one flex fuel tune. We will check datalogs to be sure everything is normal and do any fine tuning that is needed. This update requires that you have installed a compatible flex fuel kit. If you only have a pump gas tune from us, you need to purchase the full Flex Fuel update here: https://www.boostedperformancetuning.com/products/ecutek-tune-update-flex-fuel Tune Type: Naturally Aspirated - for all non-boosted setups Forced Induction - for turbocharged or supercharged setups
