PCM Conversion Information

[Wolfie]

Yes, it is DBW

Here's the updated list with Wolfie's info.

Brings up a good item to maybe add .... which years / OS's went to DBW. Think the vettes lead the pack, but not sure when and if it was still under the LS1B (512K) or if it was the 1MB.

Hello Darren,

DBW and DBC applications have some overlap – the following are “general” applications.


DBC

• all ‘96+ Vortec PCM applications
• all ’98-’02 Camaro
• all ’99-’02 Gen III pickups / vans
• all ’99-’01 Gen III SUVs (some ’02 were DBW)
• all ’01-’04 LS1-B PCM V6 trucks (ie. S10 / Sierra)
• all ’04 GTO
• some ’03-’07 Gen III Express / Savana van

DBW

• all Corvette applications
• all L18 (8.1 L) engines
• all ’02+ Gen III Escalade / Denali
• some ’02 Gen III Tahoe / Yukon
• all ’03+ Gen III trucks
• some ’03-’07 Gen III Express / Savana van

Taz

Awesome thread. Subscribed. I will make my notes/revisions once we confirm all the do's and don't's of our 6L80 project!!

Hello TBMSport,

Thanks for taking the time post. Glad this thread has met with approval. Your input would be greatly appreciated - we're a little light on some information - Gen IV specific (ECM # / TCM # / OS #) is definitely one of these areas.

Thanks again ....

Recently was able to gleen a little data from ScarabEpic22 on the P10 / P12 PCM's.

As always, if you see any errors, please let me know.

Thanks,

Thanks for updating the chart

Nice, Im pretty sure about the 07 P12s being 58x/4x but Im talking with some guys who build the I6 and who are ripping down a few 07s to double check for me. Know 02-06 and 08-09s for sure though.

Great stuff!

If I may add: The E40 LS4 is 24X/1X. All '07+ (E67) LS4s are 58X/4X.

Also, the LS4 goes up to 2009 with the Impala SS and LaCrosse Super. So you will have to separate them under the "E67" row as the Grand Prix and Monte Carlo ended in '08 and '07 respectively.

As far as the LS2 TrailBlazer SS is concerned:

A few points:

The 06 TBSS is a 24X engine with the E40 ECM.

The 07 and up TBSS is a 58x engine with an E67 ECM.

The 58X version can be run with either an E67 or an E38 (if doing an engine swap).

The 24X version runs with the E40 (or an older LS1 PCM if doing a swap).

ALL 2006 TBSS are 24X with E40.

The E40 will not run a 58X engine.

I believe the same applies to the 5.3L in the TrailBlazer as well.

Hello GXP25,

I’m pleased the thread met with your approval. Darren (turbo_bu) had a great idea when he initiated this thread.

My experience is primarily with the Gen III - just getting into the Gen IV a little bit at present.

Your input is greatly appreciated - the accuracy of the information is very important to all. Just want to clarify your comment on the LS4. My understanding was that LS4 engines were Gen IV from their inception, with no transition from Gen III to Gen IV - as happened with the LS2. I have never disassembled an LS4 - so I'm not sure.



In Darren’s chart:

• 05-06 Grand Prix GXP and 06 Monte Carlo SS / Impala SS are listed as Gen IV - controlled by the E40 ECM
• 07-08 models are showed as controlled by the E67 ECM
• 09 models have yet to be added
