Hello!
I recently got a generic OBDII scan tool and I have a question.  When
the scan tool tells me the ignition timing, is that the ignition
timing as i would read it with a timing light?  On my honda civic it
is hard to see the timing marks on the crank pulley, so it would be
great to set the timing with the scan tool instead, however I am
thinking that may be too good to be true.  How does this work?  TIA
