what to monitor? (gauges)

[geesus69]

right so far i have a water temp gauge, oil pressure gauge and am about to order my oil temp gauge

out of this choice, what other would you monitor, or would you not bother and just go with what i have already?

choice is:
fuel pressure
air/fuel ratio
exhaust gas temp

comments please

Get a wideband and monitor AFR. The engine is a standard 172 lump so if your using the correct fuel pump and reg, fuel pressure will be fine.

actually, what management is it on? Standard mgmt iirc? in which case there is not a great deal you can do about AFR anyway, so i'd stick with what you have.

yeh i set up the fpr when i fit it, so i didnt see much need

and as you said running standard mgmt so not alot i could do about afr without a remap?

and as for exhaust gas temp, i dont really see the need for that either?

with your standard management it's a pretty safe setup as long as the fuel rig is correct. 16v tanks have a swirl pot as standard don't they (or at least they are safe for track work).
As long as you know what your oil is doing, i'd say you'll be ok.
