My all time favorite mod I have ever done to any of my cars is making my turbo s2000 flex fuel compatable with the aem ems series 2. Boost and timing is all automatically adjusted and is dependent on the %of ethanol in the tank. My s2000 makes 442whp on 91 octane and 650whp on e85. It will make anything in between wether I run E40 or e60. No more switching maps or draining tanks of pump gas or e85 to switch fuels.
I want this for the evo x.l as I plan to buy an evo x soon.
I see that aem does not make an ems for the evo x. Is this correct? Is that a way to make the stock ecu flex fuel or are there any other after market ecu's that are flex fuel compatable?
Here's a pic of my s2000 after I just pumped 6 gallons of 91octane into my take of e85.
