Tired of measuring ethanol content at the pump to make sure you are at the mix you want? Tired of having to flash everytime you want to go to a different blend or from pump to e85? The MOTIV Flex Fuel Box is the only true flex fuel integration tune for the N54 platform.

MHD has created custom logic and integration using the MOTIV Flex Fuel Box to bring OEM Flex Fuel to the community. Every necessary table will interpolate between a pump gas to full e85 map (and every blend in between) without touching a thing. Fill up and go regardless of the mix. 

Flex Fuel through MHD will work for both flash only and JB4 back end flash users. Any and everyone can benefit from this!!

Included with the MOTIV Flex Fuel Box is a PNP harness to connect to your DME and your Ethanol Content Sensor.
