VincentB Posted January 15 Report Share Posted January 15 Hi, I would like to know if it's possible to add a mechanical switch button to switch from SP98 gasoline to E85 ethanol map ? If possible where I wiring my mechanical switch ? Quote Link to comment Share on other sites More sharing options...
Confused Posted January 15 Report Share Posted January 15 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!
