OM617 M-pump timing?
OM617 M-pump timing?
U got to find your own time cause the diff devices have diff reading delays.
But u sure can try 16.5 ° Btdc as start of injection with the clamp on the line at the injector.
Then probably u have to advance, as much as 18 to 20.
I have a stanadyne, and in my device i set between 16.5 and 20. Depending on engine and mods done.
The 4 valve engines stay good at 17.5 with 7.5 pumps.
I think no one can really say .....
