    Well, lol you are not wrong about that .. He ha had nothing but race fuel in that since he rebuilt it ( again ). He ran pump gas 2 times and boom... Gone. If you can't see detonation on that piston you need your eyes checked.. Hot spot in the middle, and sandpaper like pitting on the edges... Keep running your pump gas.. I'll run VP, to each their own. Eric said he's buying it by the 55 drum now lol

    If he was jetted for race gas and then ran it on pump gas no kidding it blew up. If I tuned my race car for 110 and then ran pump it would also detonate. A higher effective octane rating = greater protection against detonation. This isn't rocket surgery...

    Yes! He's a fuel scientist, right after he performs triple bypass on a rocket...

    Says the guy that can't type the words "pump gas" without using a degrading adjective before it :confused: Did you get beat up at Speedway once upon a time?

    Nope! I go there once-twice a week to fill up my cars/SUV. A crappy product deserves a degrading adjective...

    So if your worried about protecting your $6,000 investment by running race gas, why dont you run race gas in your car? Cars cost more than a bike.......

    The current o.e. produced fuel injected MX bike will not automatically compensate for a rich or lean condition that is not within the parameters of the given variables already stored in the ECU. (fuel/ignition maps) It deff. will not compensate for the amount of ethanol in the fuel.

    For the purpose of this conversation the biggest problem with ethanol in our fuel is it produces less energy than an equal volume fuel/gasoline without ethanol.

    Unless it has an exhaust O2 sensor, it won't compensate for anything except air density based on whatever the heck the manufacturer decided would be the right fuel. As far as I know all the F.I. mxers are like our YZ250F and run open loop - no exhaust O2 sensor.

    With an O2 sensor they could compensate for a lot more but would require a detonation sensor to compensate for low
    octane fuel.

    This is getting crazy... I'm going back to 40:1. I quit.

    I'm not sure why you think they would compensate for air density.

    The only sensor that actually measure anything close to density is the MAP and we know it is just reading pressure. That is the reason the ECU can compensate for altitude changes.

    There are a couple other sensors that will help it make corrections to the burn mixture, such as the IAT and CT.

    ...but ya, old school open loop!
