2002 Avalanche unsuported tune PID's

[LS1_Dragster]

OS=12209203
cal= 12208941
def file= 12209203.calz

I'm trying to use any of the tune PID's and they are showing as unsupported.
cylair_dma
dyncylair_dma
dynairtmp_dma

How do I get these to work? I was reading and the 2002 should be able to use these PID's

Lee,

Those pids do not exist in that OS/calibration (that a different 2002 than what you were reading about).

If you have a 512kB PCM, then maybe you could switch to OS 12212156...

e.g. from www/holdencrazy.com:

Download (http://www.tunefiledepot.com/EFILive/TuneFileRepository/Stock/Chevrolet/2002%20Chevrolet%20Silverado%20Truck%20Automatic%2 0LM7%205.3%20Litre%20%2812212156%29.tun) 2002 Silverado Truck Automatic 5.3 Litre LM7 12212156

I don't know if it's compatible with your PCM, but I imagine it is.

OS12209203 is a 2002 DBW OS used in Escalades / Avalanche / Tahoe / Yukon. These were a one year only item - the forerunner to the switch over to DBW on most trucks in 2003. If you are running the original 2002 DBW setup (TB / TAC / APP) in the vehicle, that is the only OS that will work.

I’m assuming there is limited support for that particular OS as it was not widely used.

Hmmm interesting, wonder if there is another OS that would work with the TB/TAC/APP setup that is supported. If not, maybe EFILive can add the DMA PIDs in for this OS.

[Taz]

OS12209203 is the only 2002 truck DBW OS that I have encountered. I believe it is the one and only OS used in those specific vehicles in 2002. The 2002 TB /TAC / APP are not compatible with the 2003 and later DBW tunes.

Somewhat of an “orphan” setup …

I may have spoken too soon … checked my database. Show OS12216125 as a POSSIBLE 2002 truck DBW OS. Don’t have confirmation - have never encountered that particular OS.

If there is support for OS12216125 - it might be worth a try. Guessing it was a limited run OS and probably won’t have any more support than the currently used OS.

[joecar]

So 12212156 would not be compatible due to DBW/DBC differences...

12216125 may or may not have those pids defined.

[LS1_Dragster]

WOW, I seem to always get the bastard child. Thanks for your input.

Would going a custom OS solve the problem? Is there a custom OS for this?

Lee

[joecar]

If there is a COS, it is based on the GM OS... i.e. it would have the same pids (or lack of).

[ScarabEpic22]

No COS for that...

Anyone else know of a 02 OS that is DBW we could try here?

[LS1_Dragster]

Could I replace the computer with an 0411?

[ScarabEpic22]

For all intents and purposes, that is an 0411 PCM already. Its not the physical PCM that's the issue, its the OS and associated hardware (TAC/ETC/APP) that is the problem.

You'd have to replace them with stuff from a Vette I believe, not cost effective. Maybe put in a support request to add DMA PID support for that OS?

There is updates to the 12209203 OS.
12212156 or 12216125 if the engine is Flex Fuel.
If anyone is running the 12209203 OS, Email support the tune you read from the truck I'll see if I have one of the later OS's here, and is the engine Flex Fuel?

Morbid truck curiosity: so the PCM in the truck has red/blue connectors, an A/C high pressure switch (instead of high pressure sending unit), and DBW throttle?

Mr. P.

[Taz]

Hello Mr. P.,

Select 2002 Truck / SUV were the first to have DBW - which became standard on trucks (except some vans) in 2003. I'm away from the shop currently - no access to database - believe there were 3 or 4 DBW 2002 OS. These may use the 12200411 PCM, but are programmed very differently.

As a one year only item - the tunes / TB / APP / TAC are unique.

Mr. P.

I'm in the same boat as the original poster of this thread. I'm running the 12200411 PCM and the 12209203 OS. My setup is a 24x conversion on a Vortec L31 5.7 and has DBW, LS2 coils packs, and just the A/C high pressure switch also. I wanted to do a CalcVET today but realized that those three PIDs are not valid with this OS. I sent a message to Blacky which brought this topic back up, and hopefully, a solution for us guys running this OS.

[GMPX]

I don't think we'll revisit DMA PID's for this OS, it's quite old and out of date, GM released an update for it.
We'll look for the updated stock files and get them hosted here: http://www.tunefiledepot.com/

[Mr. P.]

Wow; I was under the [wrong] assumption on GMT-800 if you had the red/blue connectors on the PCM & the A/C switch that it would be cable-driven TB. You gents got a "crossover" vehicle.

Mr. P.

Great! Thanks!!!
