I’m trying to use a tech 2 to view the cmp retard after replacing my intake gaskets due to a coolant leak. I’m selecting 2002 8.1 3500 from the menu since this is what I’ve used in the past after the computer swap. The issue is that I don’t see cmp as an option under the engine 1 or engine 2 data pages. I see spark and knock retard but no cmp retard. Can anyone point me in the right direction to view this data? I did a crank relearn that was successful, no codes, but a slight mis at idle. Thanks

The 8.1 doesn't have a distributor or an adjustable cam sensor, so there would be no reason to even have that.

I would select a 2002 5.7 express van(since that is the engine segment your swap likely uses) and see if it shows up then.

Thanks, you were correct if I used the 5.7 it shows up. Bad news is it’s -40, so I guess I’m going to have to pull the distributor and move it a tooth.
