I don't think GM ever made a compatible 4l80e segment for that operating system.
You can open a support ticket here https://support.hptuners.com/
Is there a newer ecm I can swap in and program?
Has anyone run this harness? What all did they change in the setting?

That harness keeps the original 4L60 transmission segments (or transmission OS, if it's a Gen 4 with separate TCM) and wiring up to where it plugs into the adapter. It comes with instructions. You can also call/email/PM Alvin. He is a real human person you can talk to, not some anonymous Amazon Marketplace drop-shipper who resells stuff they have never personally laid eyes on.

Re-pinned the PCM for the 98 harness (unique to 98).
Segment swapped a 4L80e.
2 bar operating system upgrade on SD open loop only.
It starts, drives and shifts............needs tuning but it works.
OS 12212156 > 1253002
SD 2 bar RTT
The PCM thinks it is a 2002 Camaro.
