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

[Aksl]

Hi, i swapped in a 5.3 DBW engine of a 2004 gmc xl truck and wiring with blue/green connectors of it, the pcm it had was 12576106 w.VATS, so I didn't take it.

Want to use my 411 512kb PCM from moates with blue/red connectors to run it, but cant find any calibration file 512kb to run it. Does anyone have a clue where i can get one?

Are the DBW Throttle Bodies the same green / blue PCM vs. red / blue PCM?

For most 5.3 liter vehicle applications, 2002 was the last year for the '0411. DBW was used on 2002 Cadillac 5.3 liter and some 2002 GMC 5.3 liter.

Hi Dave, truly not sure, have to figure all of that out, would appreciate any help, for now I have found limited information on repining the blue/green pcm wiring connectors to work with the blue/red pcm. But have found information that it is possible and that 411 pcm can run the lm7 5.3 DBW. Found at https://www.lt1swap.com/cable_conversion.htm

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.
