Need help finding stock calibration file of 12576106 5.3 DBW to work on 411 pcm 512kb

According to the RockAuto, the DBW Throttle Body part numbers are different red / blue PCM vs. green / blue PCM.

It appears to me the 0411 red / blue PCM will not work with the green / blue DBW Throttle Body.

Even if you repin it?

According to Rock Auto, the Throttle Control Actuator (aka TAC Module) Red / Blue PCM vs. Green / Blue PCM are different part numbers. It appears to me the 0411 Red / Blue PCM will not work with the Green / Blue DBW TAC Module.

Maybe a Drive by Cable (DBC) Throttle Body Conversion is an option? The 0411 has the correct Idle Air Control (IAC) circuitry for a DBC Throttle Body. The Green / Blue wiring harness can be repined for DBC.

If the 2004 Green / Blue harness is repined for a 2001 - 2002 DBW Throttle Body, TAC Module, and Accelerator Pedal Position Sensor.

2001 - 2002 DBW parts required.

Schematics Posted above.

The dbw pcm's were used in the corvettes and some 8.1. red/blue puters p01 style since at least early '99. Not sure of the questions.

Good information

I think the plan is to use a 2004 Green / Blue DBW harness on an 0411 Red / Blue PCM. The challenge I see is the part numbers (according to RockAuto) for APP. TAC, and Throttle Body are not identical Green / Blue DBW PCM vs. Red / Blue DBW PCM.

I may have posted this earlier or someone else has.

Dave w, you are absolutely right, can not use the 1999-2002 411pcm to control the dbw 2003-2007 DBW gas pedal, bcmTAC and throttle body. If i want to do it, have to get the gas pedal, TAC & throttle body of a 1999-2002 DBW vehicle.

Thank you all guys for so much info!

I guess i just have to reflash the pcm from the doner truck to delete VATS, just got it today of the junk yard, tried it, the engine starts and just shuts.

Have already bought a OBDLink MX+, downloaded the LS droid app, made a bench for pcm, and couldn't get it all working. On one phone it just doesn't connect to ls droid at all, on the samsung pad it connects, but brings up a message, that:

"The device took to long time to respond to one or more of the setup commands.

Check the device and make sure it is powered on and working correctly.

The power light on the OBDLink Should be on Solid and NOT blinking or OFF.

The Bluetooth light on the OBDLink should blink slow when your NOT connected to the device and be on SOLID when you ARE connected to the device.

Tap anywhere on your screen to clear this message."

That is where i got stuck totally..

Have just spent money for nothing, as i found out that the odblink with firmware higher than 4.3.0 will not work with ls droid, and mine is initially higher..(((
