Does the spark timing depend on the Cranking RPM setting?
I tried to start my engine today and the timing was off. Now when I have checked things I found that my Cranking RPM was set to 300 and the real RPM while cranking is 200.

Cranking rpm is the switchpoint at which MS leaves the cranking settings and goes into RUN.
Was your timing off in cranking or run ?

During cranking the code uses the "cranking advance" setting to determine the advance when in timebased mode, or fires directly off the input signal in trigger return. So verify these settings are correct.
