Which one is easiest for a bracket racer...Been trying to research them, and holy cow...They can be very complicated. None of them look easy to use or cheap. I am simple and just want to keep an eye on mainly the tune with different carburators.

Looking for sothing either wifi or SD card...

Need the following:

water/engine temp
fuel pressure
oil pressure
bat voltage
rpm

A/F Ratio?

Been looking at this one:
