Post by: phaetonv10 on June 04, 2008, 12:44:23 am

hey guys...
I ve read the advance timing=bad thread and i have one question...
when you advance the ip, the feul is injected after TDC or before TDC????
what i thought was the reason for the increase in acceleration is that the cylinder fires after TDC....
someone correct me please!!!!!!!

Think of this this way... when you *advance* the timing you are moving it more and more in *advance* of TDC.
