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!

dzidaV8, I know I said it before, but I'll say it again: this is really great work. I can see it would take a lot of effort to sort out these inputs. I'm going to try using your XDF for some tuning a few months away. Hope it goes well! :)
A couple things I noticed in the Engine Calibration of your XDF:
1) {B4610} Heater Warmup Intake Temp Threshold = shows significantly different values in TunerPro vs EFILive. Check the data label?
2) {B4359} A/C Torque Loss Spark Correction (Idle) Option = I believe the data label location is correct. Is the logic that interprets the "Set" in your XDF editable? I can toggle between "Set" or not "Set" and EFILive shows a correlating change, but the opposite as in: checked "Set" = "Disable"; while not checked "Set" = "Enable". (Seems to be the opposite of what I'd expect? Or perhaps EFILive is incorrectly interpreting this?)
I plan to keep looking through your XDF more before I start further tuning with it.

For others who are thinking about trying this 2002 12212156 XDF, I wouldn't be afraid to try it out. I've been using it on two different PCM (a 411 swapped in a '00 Silverado and a 2002 Camaro). I've flashed probably about 20 times now, and not a single problem with any corrupt checksum nor any bricked PCM.

Thank you Chas for your feedback! I have fixed those issues, see xdf V5 in the first post :)

Would it be possible to add the A/C System type parameter to this xdf? I would like to change from the pressure switch system used on the trucks (type 3?) to the pressure sensor system like what is used on the F-body (type 2?) and enable 2 speed fan control based on A/C pressure.

Sure, I added an updated xdf to the first post :) And there's a lot more, beyond the A/C type switch.

Awesome. Thanks a lot!!!

The Min and Max labels under A/C [Disable/Enable] [Min/Max] Refrigerant Pressure appear to be reversed. Everything else looks good. I appreciate all your hard work.
