My car has a digi cluster ran by the gas burners EEC.Soooooooo,,,,,,,
I am looking at gauges to cover my turbo diesel conversion.Here's my list so far.

Speedo
Tach-Magnetic or optical for a 5 cylinder diesel
Fuel level
Oil pressure
Engine temp
Oil temp
Pyrometer
Boost/vac
Volts
Amp

Have I left out anything or missed anything?I will be running a manual transmission,so I don't feel that I need a tranny temp gauge or pressure gauge.
