G4X PNP HC92X Flexfuel map switch


Recommended Posts

I would strongly recommend against this - but instead just install a Flex Fuel sensor - and let the ECU take care of it.


Also, if the quality of your "E85" fuel changes - which it likely will - again, the ECU will just take care of it. And, in that period where you've got a mixture in your tank and lines - the ECU takes care of it.


Ideally you want as little human interaction with regards to the core fundamentals and engine protection - instead add the relevant sensors and let the ECU do the heavy lifting!
