'0411 PCM V6 vs. V8 Differences?

[dave w]

All of the 512 Kb PCMs (Blue / Red connectors) are mutually compatible - whether a 4896 (99-00) or 0411 (01-02) variant. These will operate V6 truck engines, Gen I (Vortec) engines, and Gen III LSx engines (4.8/5.3/5.7/6.0/8.1).

The 1 Mb PCMs (Blue / Green connectors) used from 2003 until 2007 are NOT mutually compatible.

Good information!

I'm wondering can an OS from the '0411 be flashed into the '4896 PCM? ... I recently encounter a '4896 PCM, that I wanted to flash with an '0411 OS. I decided not to flash the '4896 PCM with the '0411 OS. I went ahead and modified the '4896 OS.

With EFILive - absolutely no issues in doing this.

With TC - doing this will often corrupt the PCM's unique serial number - making it impossible to license the controller with HPT or EFILive in future.

TC appears to use one flash protocol with the 1999 & 2000 OS, and a different flash protocol with the 2001 & 2002 OS.

same part numbers = same parts. any 0411 should be identical to any other 0411 in terms of hardware, software will obviously be dependant on vehicle.

The PCMs being discussed here have a Service Number, Hardware Number, and 4 letter BCC designation. Match all 3 of these, and you have the same part. The early PCMs (512 Kb) are fairly forgiving - the later 1Mb PCMs are not.
