  • Chip upgrade

    I haven't messed with my ECU in a while.
    Now that I am back to it, I wanted to upgrade from 1.09 to 1.12 chip on my SM4 Stand Alone.
    I am running on E-85 and have the sensor in place already for that flex fuel support.

    I see in the "MRM-Racing Web Shop" it's out of stock.
    Is mailing the ECU to Australia the only way? (I am in US)
    Seems like something you just pop into a socket, or does this involve soldering ?

    Thanks,
    Mark

        So, maybe I am confused. Do I need to pull one chip out and put another chip in to go from 1.09 to 1.12 or to 1.15 ?

              Check the Autronic dealer list. 1.14/1.15 is not yet released.
              He gets his lap dogs to do his talking for him. Buzzard is a good example.

                I've talked to a couple in US, and they said they don't have 1.12.
                When do you think 1.14/1.15 will be released ? Should I wait ?
