I have decided to use Zero Decibel’s dash bezel. Therefore, I will have 4 52mm spots to fill. Now I need to choose the 4 and the brand and model while knowing very little. So far I’ve seen the following in the forum:

Boost
Oil pressure
Oil temp
Exhaust gas temp
Air fuel ratio
Voltage
Other?

I have a JDM EJ20 motor and will be using iWire but can’t use Cobb because of the JDM.

If you were to pick 4 with what you know now what would they be?
