Boost Delta Questions

[DTatom]

I just got my trinity installed on my early 04 dodge ram 2500 diesel 4x4 and I wanted to monitor my boost pressure.. But all I could find is the "boost delta" it measures in psig. Is there just a regular boost setting? Or can someone explain the boost delta to me please? Thank you!

under synthesized PIDs, at the bottom of the list, do you see it there?

[DTatom]

No sir, only thing there is the boost delta

[mikel]

so, when you get the list of PID groups, you dont have a 'synthesized' group at the bottom of the list?

1r08 revision?

[DTatom]

Yes 1r08 with all the updates. Only one option under synthesized is the boost delta. I don't have just a boost option..

[mikel]

OK, then thats the correct one.

what are you looking for?

that should show boost pressure starting at 0.

[jimb]

The "boost delta" under Synth PID's is gauge pressure in PSI.

[DTatom]

When it says like 3.26 is that 3 psi? Or another value?

[jimb]

Yes, 3.26 PSi gauge relative to Atmospheric pressure.

[DTatom]

Oh okay cause I am only getting 22 psi at WOT and no smoke out of the performance tune so I'm trying to figure out if I've got a problem or not. I got a Volant cold air intake and muffler delete as far as performance stuff for now.

[mikel]

to my recollection, 22-24 psi is normal.
