    Hi everyone,

    could you give me the good timing procedure for my 1977 318ci with Auto transmission .... It's writen inside my service manual 8° BTC.

    I know :
    - Neutral or Park on transmission
    - vacuum hose disconnected (and plugged)
    - engine at operating temp
    - idle set @700RPM
    - strobe light on the 1st spark

    but ...

    this 8° value must be reached at which RPM value ???? idle value ?? 2300RPM ???? 3000RPM ???

    Every car I ever had was checked at idle.

    Todays fuels are not the same as the fuels sold back then. That said your timing will be greater than 8 BTC today... expect 12 or greater.
