I cannot seem to locate what the actual timing in degrees should be for a 6.2 Diesel. I have aquired a Snap-on MT-1480 and can measure the actual injector pump timing, but it seems to be some kind of dark secret. Not even my factory manual lists it. I like the one post that says advance it until it sounds like a Ford and then back off.
The vehicle is a 1988 GMC Jimmy with the 6.2 and 700R-4. I have recently swapped the intake with a non-EGR manifold and would like to fine tune the injection pump timing as well. It currently reads about .5 to 1 degree ADC at 600 rpm and 3.5 to 4 degrees BTC at 1500 rpm. I notice that the pump has been moved slightly to the advanced side of the mark.
Thanks!
