Hi Guys for 3 nights now ivé been searching the interweb and trying to read hightech english. Im danish and im pretty good at Hightech english and Engine tuning but im getting confused.

First the engine we are talking about is a 13 b 4 port with 12a center iron. 48 mm ida and Dlidfish with 7 Pin HEI.

now here comes my problem in the manuel the timings is set to be 0 tdc for l1 but that would be with engine running at idle no vacum and 0 on the timing gun. Im keep on reeding guys saying to be careful with Knocking how can you get knocking with 0 degrees TDC. im running 100 octane and i would really like to time the engine correctly
