00 to 02 os question

[leres]

It is very common practice from what I've seen to go to the latest version of the OS's. Camaro/TransAm for instance go to 12212156 for instance.

I upgraded my 2000 SS from 09381344 to 12212156 over a year ago and haven't had any issues.

Here are my notes:

Base calibration is a stock 2002 Camaro/Manual (OS 12212156)

Modification summary:

• Enable EGR
• Update Engine DTC Processing Enablers from 2000 calibration
• Update Engine DTC MIL Enables from 2000 calibration
• Update Injector Flow Rate table from 2000 calibration
• Disable CAGS
• Remove speed limiter
• Tweak fans on/off settings
• Change to 3.73 rear gear

Since then I've done some VE and MAF tuning. (It has passed smog in this configuration.)

There are some stock 00-to-02 tunes out on holdencrazy, or - if you have a modified tune on your 00 now - just go through the hazzle of copying them one by one ...

Thanks - that's the kind of info I was looking for - specifically, with the different injectors and intake, what 00 tables need to apply, and beyond those, what else? I have a host of A4 tranny mods that I'll need to transfer, but I think that'll still be easier in the long run than copying VE to backup tables. I plan to build a 12212156 with all my mods and the necessary 00 tables and then flash it.

I went from 99 to 04 tune on top of an 04 COS5, well 3 originally.
Other than injector flow for the girly 99 injectors I just used a stock 04 HSV tune. Gained 35KW right off the bat. Then went from there.
