2002 OS 12212156 .xdf

At this point, if you have a 2002 pcm, I would say it's easiest to just get your hands on a 2001 bin file, and tune using dimented's xdf's.

Thanks for the input everyone! I'm sorry that my files caused some trouble, I spent quite a lot of time on them in order to reprogram some stuff on my friend's 2002 Camaro, but then he sold the car and I never got to actually testing it. I have only compared checksum calculations for some changes with EFIlive and it seemed correct. I'll look into the LS1 checksum plugin and try to take this work further, as now I have two 0411 PCMs for bench testing, so stay tuned :-)

I have finally found time to finish OS12212156 xdf work. The XDF is added to the first post.
This time it's rather thoroughly tested so it should be safe to use. Please let me know of any issues you may find.

dzidaV8, first I want to emphasize - great work! I have a 2002 0411 PCM I thought to play with your XDF. I have a 2000 Silverado that I'm trying to upgrade to the 0411. :)
Your XDF has helped tackle a lot of the minor changes, but there are a few that does not seem to be working correctly:

In the Engine DTC Processing Enablers I tried to change
P0106 Manifold Absolute Pressure (MAP) Sensor Performance
P0741 Torque Converter Clutch (TCC) System-Stuck Off
P0752 Shift Solenoid Valve A Stuck On
P0757 Shift Solenoid Valve B Stuck On
P1683 Control Module Ignition Off Timer Performance

And in the Engine DTC MIL Enablers I tried to change
P0741 Torque Converter Clutch (TCC) System-Stuck Off
P0752 Shift Solenoid Valve A Stuck On
P0757 Shift Solenoid Valve B Stuck On
P1683 Control Module Ignition Off Timer Performance

I made the changes in TunerPro (along with multiple other calib data as well as other DTC options). All the other small changes seem to work well (as the change is reflected in EFILive). Checksum changes and looks good. When I changed the above nine different DTC, TunerPro shows a change, but EFILive does not show the same change. Perhaps double check on the location of these data bits?

And another odd thing - I changed the VIN in TunerPro. The *.bin shows the edited VIN in EFILive. I flashed the *.bin to the PCM. Then I re-read the *.bin from the PCM and it did not show the VIN number changed. I used Antus's tool to change the VIN and that was successful.

The truck runs great with the 0411 PCM so far, but not quite perfect yet. No SES light and no drivability issues that I see so far, but I'm having a phantom DTC lighting up the battery in the Message Center despite the voltmeter showing good voltage. (I think) I have tuned off the DTC for the battery, but still getting this message. I'm still investigating this. (Switched back to old PCM and no battery message.)

Hi, thanks for your kind words :)

I checked the DTC tables, and you're right - there were mistakes in some row labels. I fixed that in version 3 of the xdf that I just attached to the first post of this topic.

You cannot change VIN by just altering the bin. The area containing VIN, serial number, etc. is not written during calibration flash. You need to use "Request to Write Data Block" diagnostic commands to change those parameters (for example using Antus's tool).

Version 4 of the 12212156 released! (in the first post) Enjoy! :)

Added new parameters:
- Cranking VE Baro Multiplier and Calibration Temperature,
- Commanded Fuel For Extended Cranking,
- MAF Airmass Filter,
- Dynamic Airflow parameters,
- VE Correction parameters,
- Priming Pulses parameters,
- PE enable parameters,
- LTFT deadband, update rate, and filters,
- Idle STFT parameters,
- Torque Management parameters,
- Coil Dwell Time parameters,
- Shift Light parameters

New categories, better parameter descriptions, more organized category view.

I think this XDF is pretty much finished, tested on a dozen of cars and works perfectly!

I downloaded the OS for 12212156 and the plugin that you have listed and I have saved it to the proper location. I cannot get a bin saved without checksum errors and I don't know what to do. I have no issues using 12208322 with the GM-P01-P59 plugin I just can't figure out what the problem is. Any help would be appreciated.

Hey barn dog did u ever fiqure this out, i am also trying to run a 2002 4.8 lr4 with a manual, using this os that ends in 56 i have copied the file in the plug in folder looks like a bunch of coding only readable part says something ls on top line, i have tried finishing the tune with ls droid and it just stops a lil after silence bus crap with ? mark. Andt to top it off i cannot find the original read me plug in to see if that the problem or i am also wondering if this xdf is only for v6 since that what it says at the end of it, if this is not correct please direct me to correct xdf.

Try the attached version. Make sure to copy the plugin file to the plugins folder.
