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?
