Thanks. I'll take a look at this and give it a try. I don't remember seeing a load based table in EFI though. I'll look again but the pw stuff may do the trick.

A load based table is not accessible with efilive yet. Also note that with the pw truck max mm3 will still be 94 but you should see a higher pulse and more fuel
How ya getting more fuel if the ecm is limiting quantity? PW just spreads the commanded volume over a longer or shorter period of time with pressure adjustment. At least that's how I've understood it. But then I've discovered things about this ecm that I don't really understand too.

no
commanded volume is just a reference number. you can adjust how much fuel you are actually feeding the engine by changing your PW and/or your fuel pressure. even though you are maxxing out at 94mm3, you can still force as much fueling as you need by remapping your PW table to take into consideration that 94 is "max" and scale down from there. you will likely lose slight driveability.

Thought of trying to find a truck ECM?

what about using an 06/07 ecm for a 5.9? i see you arent using the stock VGT anyway

Ok. I've been able to make some progress with pw changes. But I have not have any luck getting the fuel pressure up. I've adjusted the pressure table, the duty cycle table, and the FCAC table and none of them have made any difference in commanded or actual fuel pressure. How do you get the fuel pressure up?

Also now that I have gotten the pw's up I have developed quite a fuel pressure oscillation. Not during cruise as some have had but under moderate acceleration. Anyone seen this before?

Have you adjusted the limiter tables?
