I need to grease the 2 rear regulators up then hopefully some testing will be done. I still don't have a great road found, but I have 2 that show some promise. The speed limit on one of them is pretty low though. Only 45 mph the other is 55 posted, so "60-65" mph to the general public
No, it will also be vital in providing the right acceleration enrichment and transient timing advance during throttle changes.

Probably has (my guess only) 1/10th of a second filter.

What are the rear regulators?

(Addition: In the very old days - like the late 1970s - EFI cars in fact ran throttle position switches rather than sensors - just idle and full throttle contacts. My 1977 BMW 3.0si with Bosch L-Jetronic had that.)
