hey guys i was just wondering what guages everyone normally runs for FI.. i have the three guage pod and obviously boost and air fuel/wideband are the two but what do most people run for a third? i ordered a fuel pressure guage. that ill use.

 

boost
oil press
oil temp
water temp
fuel press
a/f
EGT

your choice.

 

Fuel pressure gauge is usually in-line under the hood, at least mine is. Most common answer will be either exhaust gas temp or possibly dual wide bands. It pretty much whatever your tuner prefers. If you are just trying to fill a hole in the pod you can always get another engine temp gauge, one that is more accurate than the stock unit.

 

sorry for being a noob but what is EGT?

 

Exhaust Gas Temp

 

I have wideband and boost (aem tru boost so its a gauge and controller).

Swapping out the AEM tru boost for the Pro-EFI CAN gauge which is a super-duper multi-function gizmo.

 

you will want something to monitor boost for sure, preferably warning you if you are overboosting. EGT is good, oil temp is good and so is a digital wideband. You can eliminate a boost gauge by putting in a HKS EVC6 which will give you a digital readout (mount in cubby). A HKS turbo timer will give you voltage (mount in cubby), then you can replace that pod.

Four Defi gauges plus a wideband is about 12-$1500
Three Defi's, EVC6, and a wideband is about $14-1800
turbo timer is about $150

Remember, it isn't really possible to monitor 6 gauges at one time without concentrating on the road. I don't look at my gauges while driving hard unless they flash (luckily they havn't yet)

 

EGT is the bottom one

 

Yup,
Only gauge I have time to watch while racing is the Tach.

 

HKS Camp2 monitors everything but you would also need to have an HKS Fcon iS or Vpro.

 

IMO.....minimum gauges should be air fuel and boost.

 

Ummmm no you don't.... The CAMP2 on its own will monitor and display (w/ warning option) all of the common parameters through the OBD2 port. W/ some added parts, you can monitor other things like boost, and EGT. A/F i don't believe is quite that easy. For that you will still need a wideband controller, and i'm not sure if the knock monitor will give an output signal to the camp, or if it has to go through an FCON to work.

 

IMO your best bet is to have an EMS that is monitoring everything (through the help of addition sensors if needed), that automatically adjusts/fixes/retards/cuts/lowers/backs off/etc, if something gets outside of a parameter (i.e. fuel pressure drop, oil pressure jump or drop, a/f too lean/rich, boost spike, etc..). If you are expecting to be able to drive, monitor gauges, adjust driving to what 6 gauges are telling you, it ain't gonna happen...thats when things go boom

+1 - Just watch the tach and peek the rearview every now and then under WOT to see if you are smoking at all, unless your tint is too dark, then just politely ask the guy you just crushed if he saw any white smoke out of the pipes when you blew by him .

 

I stand corrected, just went to the HKS website and looked at it again, I'm not sure how I arrived at that conclusion and thanks for bringing it to my attention.

 

I got the Zeitronix because it had a bit of info on one read out and didn't have to clutter the cab with gauges. I have a dual gauge pod that reads oil pressure and will have a fuel pressure gauge soon. I can't ever monitor all that stuff at once when driving, I usually just hit the peak button to see what the hi/lo paramters were after a run.

egt is important and can tell alot about a way the car is running, some tuner droped some knowledge about why and did alot better job explaining it than i could ever. i would search for it but havnt the faintest clue what thread it was in

i got boost, egt, and a/f
