Tune Update - FA2O Flex Blend Maps

This tune update is for existing FA20 (2015-2021 WRX) customers who have already purchased both a pump gas map and an ethanol blend map from us and want to blend those two maps into one flex fuel tune using the new Cobb CAN Flex Fuel Kit.  


If you only have a pump gas map or an Ethanol blend map from us, you will need to purcahse the Flex Add tune update option. 

It is recomended to have an upgraded fuel pump to run higher than an E50 blend.


We sell the Cobb CAN Flex Fuel Kit here:
