    LT5 Crate Engine kit

    Hello
    We swapped GM performance LT5 Crate Engike kit on BMW
    Now we have fan control issue.
    ECU won't turn on fan relay. Someone have similar experience.

    I turn on flag for state 0 forcibly, fan always turned on.
    But if state0 flag is 0, fan never works even if ECT is high.

    ECT threshold doesn't effect fan control

    Someone can help us?

    Did you change the # of fans fitted? Your screen is different from mine with a stock LT5 controller read.
