Automotive controllers have all sorts of data on the OBD data bus indicating stuff you never care about if you can decipher it.

Ah! thx Piotrsko.
The more electronic side of things is above my pay-grade as I've never dug into it.
NB that here you'd have a stock FWD car.
So while a real time digital rpm and power signal is likely available somewhere in/from the car's electronics, and translatable, I'd rather leave all the stock electronics well alone.
I go under the assumption that most other's think similarly.
Wheel speed is easy but:
Where would one go looking for said power signals if, like you, we knew what we were doing?
