yeah I was wondering about how rock steady it always seems to be. That and the fact that it has no hash marks or temps anywhere on it.

ok I just ordered a temp gauge for the coolant



it's a crazy amount of gauges

A/F
fuel pressure
oil temp
boost
EGT
coolant temp
and the Z has a built in oil pressure

 

why would u need egt gauge when u are sc? turbos, yes but sc no. Also your A/F gauge is a waste of money unless u get the AEM wideband one. A/F ratio gauge is just pretty lites going red/yellow/green. For sc, u need fuel pressure, boost, oil and wideband.

 

EGT's are important! Tells you what is going on after ignition.

 

right, well I have an innovative wideband A/F gauge which is said to be among the most accurate A/F gauges on the market.

A lot of car manufacturers use it when testing/designing their cars. I've actually heard the AEM one isn't all that great because it doesn't give a reading below 11 or above 17 A/F. That's pretty lame for FI don't you think where a lot of tunes rely on running in the high 10's for A/F


EGT's IMO are as helpful on a turbo as they are on a SC - which really isn't very helpful at all in general. It does give you another indication of how hot your engine is running though. I think of it as a short term temp, where oil temp is more of a long term temp because it takes longer to heat up and cool down, where EGT's heat and cool fairly fast.

Yeah you can do without an EGT gauge if you have an accurate wideband A/F gauge.

 

Not important? Blasphemy! xP

EGT's tell you what you're doing say cruising at 80mph, or what you're doing @ WOT in 4th gear. You have monitor temps to see if it is going to cause a problem in the near future. I.e. melt something,

It is also to gauge things out of the ordinary. Say you run avg of 1200F daily in cruise 6th gear, but then one day it decides to do 1400F in cuirse 6th gear, THEN you have a problem

 

I'm very happy with my Zeitronix.....

 

yeah like I said, it's a good short term temp measurement, but the temp itself you have to to be aware where your sensor is mounted. One man's 1400 degrees is another man's 1200 degrees - meaning you can't really compare temps directly with other temps from other people online unless you have the sensor mounted in the exact same spot, and you're both talking about degrees in F or C and not mixing them up.

a turbo setup is more likely to have potential to melt something, but full headers on a SC get pretty hot too. I dunno, IMO it doesn't hurt to have one, but it's probably the least important gauge

 

whats more important in a sc, oil pressure gauge or fuel pressure???

 

i'd say oil pressure

if you buy a return fuel kit, they come with a small fuel pressure gauge that is mounted in the engine bay that someone can look at while tuning

 

but how about your driving, then u can't tell if your fuel setup is working properly if the gauge is in the engine bay. What is the need for oil pressure?

 

I also have the AAM fuel return system and yes it does come with the FP gauge in the engine bay, now do you need it in the cabin well no as if you have an AF gauge then it will tell you if there is something wrong with your fuel system, probably by going to the lean side.

I just have a AF wideband, boost and oil temp.

 

you can always add a fuel pressure gauge to the inside of the car in addition to the one in the engine bay with a return fuel kit - was just bringing it up cause people don't seem to know you get a fuel pressure gauge with return fuel kits.

It's useful as in detecting if something is drastically wrong with the fuel system, but generally an A/F gauge will tell you if you're getting enough fuel to the engine - the fuel pressure just tells you how the fuel is cycling thru the fuel system. the oil pressure is an extremely important gauge - doubly so if the FI kit taps into the engine oil pan which pretty much all of them do except for the ATI kit - or maybe the stillen too? (not sure)
