Russell, sorry for the delay in response..........I've been away for most of the month.

I can't tell you the results of setting the injection timing as it was performed immediately after replacing the cylinder head, with completely new exhaust valves and new prechambers.

But, the timing was definitely late by about 3-4 degrees. I needed to rotate the pump up near the top of its range. The camshaft is late by 2.5 degrees on the crank using the marks on the cam tower.
