    hello i have the ez efi 2.0 with the fast supplied fuel pump, lines, regulator etc. also running fast dual sync distributor. I'm currently running gas and was looking to run e85. And advice on switching from gas to the e85 with this system? What do I have to do? Do I need to make a spark plug change, etc????

    The first thing will be to purge all the gas from the system and tank/s before filling with/adding the E85. The fuels cannot be mixed. Then you'll be using the handheld Wizard menu for a full reset and to input fuel type as E85 with all other asked for Wizard input and settings. In other words, you'll be starting from scratch again. The Wizard will apply ballpark F/A and timing settings you will then need to modify. You may also need to change the heat range of the sparkplugs.

    Which direction do the plugs usually need to go towards with e85? Hotter or colder?
