Ecodiesel specific PID's?

Today I got my OBD adapter, loaded Torque and am getting lots of good data.

Has anyone discovered any diesel-specific PID's (or any other for that matter) that could be useful? I'm particularly interested in fuel rail pressure and oil pressure.

There's a thread on the Ram 1500 Diesel forum about PID's and it seems there isn't a whole lot out there yet. It also sounds like they get more information on their EVIC than we do.

Those look a lot like WK parameters. The WK2[v2.0] is a completely different animal; we have different transmissions and ECU's and a new network architecture.

Re: Ecodiesel specific PID's?

Just got a cheap eBay adaptor, loaded up Torque and... BUMP!

PID codes anyone?

Cheers,
Steve

Re: Ecodiesel specific PID's?

BIG BUMP. Same here.

We need the PID'S for:

pre-turbo EGT
DPF temp
Rail Pressure
Injector Duty Cycle

Do we have an analog sensor or switch for oil pressure?

Re: Ecodiesel specific PID's?

I'm not sure if it's an acronym or just a colloquial term, but it is often a single word posted in a thread to renew interest. Basically, it puts the thread back at the top of the pile.

Bring Up My Post perhaps?

Cheers,
Steve

I want to say I read somewhere it's a pressure sensor, not a switch.

I got EGT to work in Torque on PID 78. Use Torque Scan to get it to display. Seems to be pre-turbo based on reaction time and temps. CAT B1S1 seems to be a "close enough" solution to DPF temp. It's downstream and will rise to 1000-1300F when a regen is in progress.

I forsee the Ram guys developing PID's that will cross over to our platform soon. They sure are selling enough of those trucks!

I'm lurking on the RAM 1500 Diesel forum...waiting. Its funny watching them discover some of the same stuff we have.

Ok...so you are using the raw PID scan to see PID 78. Now, how do we add it as a Custom PID? Once that is done it can be exported and shared.

Also, I have the Scanguage2 Xgauge codes for DPF. It reads in between EGT and CAT except during regen where it peaks at 1280F while EGT is 950F on flat cruise (during regen).
