Maybe someone will know what this is all about, specifically the maxxed out fuel pressure command at minimal fuel. Appears only on the Medium 4500-5500 OS.

Attached a copy of a stock file. B1001 is base pressure

Must be noisy as heck. My question is, does anyone have a plausible explanation for why such high pressure is used at near idle ops?

That table is being displayed wrong which is quite odd given the same OS on normal truck looks fine.
I'll have to inspect the file a little closer, it's probably just another wonderful "Boschism" we'll have to find a work around for.
For now, I would not change any values in the table.

I have 3 OS's for the LBZ medium duty, all showing same. Do you need me to email them?

I intentionally posted the ...128 for that reason.

You do remember that most (99.9%) of EFILive users and tuners use the last 4 digits of an OS number, right?

Yup. Just stubborn.

Anyone have any thoughts about this? I want to get this off my desk. :)

The file you posted will be fine to work with.

Ross, is it accurate as far as you know?

What was teh outcome of this issue? Is the numbers in the table correct or not? I'm considering using this OS for a dual tank BURB I'm helping somebody with since I haven;t found a 3500 cab and chassis dual tank one yet?
