Essential Gauges to monitor Engine.

[VTSTomE]

So far on my list I have oil pressure/temp and water temp.
What else would any of you say is essential to keep a close eye on things?
Cheers for any reply!

Air fuel if your that bothered

oil pressure is the most important one as that kills real quick. Oil temp and water temp is useful. If your car is highly modded (standalone etc) then AFR and EGT can give indications of anythings going wrong in the engine, there are often other signs of that though so they're more useful for mapping than anything else.

Will be on Omex, the companies software who's mapping it will have all the age etc values. Will look into an afr gauge.
