Banks iDash parameters for the LM2

[972sparky]

Here is a link to the idash parameter list for the LM2 in the GMC Sierra 1500. The parameters are mostly the same for the 2022 Tahoe/Yukon. I will list the ones that are not in the new v1.24 update as well as a few others available that are not on the list.

All the air density parameters are available

All the diagnostics are available except TIME, time data log

All the emissions are available except DPF SL, DPF soot load percent (there is a dpfdp1 DPF delta pressure in the pressure list that is the same data I suspect, just not converted to %), LSTRGN distance since last regen.

All the engine performance air are available except THRT-R throttle position relative.

All the engine performance fuel except none of the injector balance rates. There is also a FUEL TEMP not listed that is available.

I don’t have a pedal monster but i suspect if you do they are all available.

All the pressure except OIL P engine oil pressure, TRAN-2 and TRAN-3 are available. There is also a clutch pressure available.
(I am disappointed the oil pressure isn’t available, the factory dash gauge is quite vague and looks quite low most of the time)

All the speed and velocity are available.

All the temperature are available and include cylinder head temp, exhaust gas temp 1, exhaust gas temp 2 and exhaust gas temp 3.

All transmission are available except 4WD-S transfer case status and TR SLP transmission slip. There is a torque converter slip available.

All vehicle performance and voltage are available.

BIDS

I am making some new pages and haven’t tested all the parameters for relevant readouts yet, but will post update if any don’t seem to work.

If the link to the list doesn’t work, go to the banks web site and then the idash/monster gauge page and locate the 2021 GMC Sierra 1500 3.0L parameters page.

Wow - nice investigation!

It’s interesting that the ‘21 LM2 in the 1/2 ton is able to provide more information than what you can get on a ‘21+ SUV. There must be a difference in the ECM. I wonder if the ‘23 w/ LZ0 is missing some parameters?

The development cycles of the pickup and SUV are slightly staggered so it makes sense that some of the ECMs and software could be different.

As far as the oil pump pressure, I’ve noticed it seems to be pretty low, but as I understand, it’s a variable displacement pump to minimize pumping losses, so it’s only going to pump what the engine needs.

Make sure you have the correct vehicle/motor selected under settings. Go to settings...vehicle...and select LM2 20-21'.

Now you should have everything listed in the PID list.
