Update:

Have been struggling with the TPS Autoset on the Dominator EFI using a DBW throttle body, as well as finding time during the busy holidays to work on it!

Last week, I started drilling down on the DBW harness wiring diagram, which is in the instructions, 558-406 Holley part number. Then I noticed, while skimming the entire doc, that the harness only had 2 TBs listed as 'compatible'. Hm. I remember specifically that there being a handful of supported TBs in the Holley Dominator 'Selector Guide', which I pulled up. Sure enough, there's a big list.

In the selector list, my TB was listed, as I knew it would be, and it's not listed in the harness' instructions. Ok. So I go to look up the TBs that are listed, and, the are both 'discontinued' GM parts, but can be found NOS. Uhg. They were not cheap.

So tried to figure out a work around, and basically, I loaded an LSX TB config file, and was able to get it to work without changing any parts. Cool.

This week I need to finish my ignition map, but will be ready to fire it off this coming weekend. Finally!
