Re: HELP--Can this be done?????
i think mallory is the only one that makes a evenfire crank trigger setup.. You can make it work, but you will have to rewire the complete engine harness to make the XFI work, and add a cam sync. Sequential is nice, but b/c the backside of the valve is pressurized in a focred induction application, it really will not give you any noticeable power gains unless you are tuning each individual cylinder which only happens in a pure race application.
As for the gas milage, 25 mpg is dreaming but with a regular b2b setup and interface harness the portion of the map for cruise, and slight acceleration can be leaned out to give you decent gas milage without the hassle of sequential setups.
