    I would love to go with E85 on my turbo FZR, but it's not readily available in my area. Hopefully soon!

    Are those maps only for the Bosch ecu?

    Wow, how big are the injectors on that setup?

    see http://fuelinjectorclinic.com/flow-calculator

    I would bet that would take a little homework to get that running correct.

    Currently the E85 tune is only for the newer iControl skis

    The E85 tune is for use with the V-Tech VT1100 injectors.

    Expect some serious rpm gains from this... On e75 gains I've seen using VTECH mapping has been minimum 220 rpm (I say minimum because it threw me straight onto the limiter of 8800!)

    Things to take note, you may need to monitor your e85 content if buying from the pump... The fuelling changes considerably going from say e85 to e75 to e90 etc....
    If you find your fuel outlet serves higher than e85%, you can mix in some high octane pump fuel to get back to e85. (Usual e85 blends contain 95 RON, emulsifiers/stabilizers, ethanol and 2-3% emulsified water --- All ethanol blends have some % of water, which is emulsified and not separated unless very high water content is reached. Think of it as water/eth injection )

    E75 maps are also available. (Which can be helpful for 'first fill' e85 or if you can't get higher ethanol content locally.

    Controlled drums of e85 are a sure fire way to know what you are getting.

    The amount of torque will pull your arms out of your sockets.

    VTECH will only tune for ethanol on Bosch ECU's using VT1100cc injectors. Please visit the online store to find these.

    What are you using to determine the volume of ethanol?

    Here in the states ethanol content varies on season, could this affect the tune?

    Also here in the states E blends are blended with low octane hydrocarbons. There is no hard spec on what type of fuel quality is to be used for blending E. To be honest you won't see much a difference blending with a high or low octane due to the high octane of ethanol. EcpChris and myself just performed this last week for a major oil company in the northeast

    Check out ASTM D5798 and Get your hands on some anhyrdous ethanol!!
