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

Here is the latest with the updates for LS4 and LS2 information. Please post up if there is anything that is incorrect.

Thanks,

one pcm I`m not seeing is 12581565 would this be a suitable unit to retrofit into a 1989 K1500 with TPI, engine is staying Gen1 but I am having EFIconnections 24x reluctor installed. Wondering about gauges, 40T transfercase reluctor on the 700r4. A Silverado is in the wreckers now and I can grab the complete harness, coils and ecu. Perhaps there is a better choice- 411.... but this is here and now.

Good deal

Review comments:
- might be easier to read if you split LS1A and LS1B(512K) into their own box rows.
- LS1B(1M) and E37 have blanks for ckp/cmp.
- should the early E40 have 24x/1x...?

Hello turbo_bu,

The chart is starting to take shape nicely. I don’t have software to edit PDF files, so I wasn’t able to make changes directly to the document and send it back to you.

Rather than make a bunch of scattered comments, are you able to import the current information in the chart into a Word or Excel file ??

I believe the Forum software accommodates posting Excel files (*.xls) directly. A Word file would have to be put into a zip folder and then posted.

I could then make changes / suggestions directly, and save us both a lot of typing. Forum members would still be able to view the chart’s progress and comment, each time you reposted it.


Regards,
Taz

I actually have it in Excel. Just figured everybody didn't have access to view it or edit it. I will post the Excel file on Monday (it is on work computer, not at home). Please help to correct or add anything that I am missing.

Thanks for your help,
Darren

Here's the Excel file. Please feel free to add or make any corrections.

Hello Darren,

Thanks for posting the Excel file. I added columns for PCM “Common Serv#” and “Common OS”. These are based on my experience; in my part of the world, and may not reflect global commonalities. Adding columns required some format changes – portrait to landscape, and some tight margins, to name a few.

As you can see from the additions, my experience is primarily within the Gen III engine / LS1-B PCM.

I corrected some misinterpretations from previous posts – mainly in the E40 information.

Hopefully these additions are consistent with your original intentions when beginning this thread.

The Gen IV (E38 / E67) and “Inline engine” (P10 / P11 / P12) information is a little sparse. Hopefully forum members with experience in these areas will take a moment to post some additional information.

Regards,
Taz

How do you tell Excel that you're entering just text and not math...?
