Question, this has been bugging me; let's say you install a cam @ 106 would this not effect the basic spark tables?.

I noticed a new option for tcc, well new because i'm new to it called
"spark table bias". if i'm way off base can someone fill me on.

Thanks in advance no pun intended..

 

Will not effect anything about the plug firing. The 106* is the installed intake centerline and controls only the intake opening and closing points which in turn will control your DCR.
