will i need a boost gauge if i have an electronic boost controller eg. greddy profec a? also, what three gauges would be the most vital into maintaining a turbo setup?
1) boost 2) oil pressure 3) exhaust gas temp... i've been told a/f gauges are just pretty to look at. which do you think are the 3 i "need." thanks

 

3 needs..

1)boost
2)egt
3)a/f

 

I cant stand looking at my A/F guage bouncing all around all the time and it doesnt look right next to the pretty boost gauge Plus isnt it only accurate at WOT and sometimes on stoich? !

 

noob question

why do you need to know the exhaust temp?

 

1) boost
2) a/f from wideband
3) nothing else

 

If you are leaning out in boost your exhaust gases will be hotter.

 

anyone else have an opinion on the matter?

 

a/f gauges are pretty much crap.

 

unless you get a wideband, which you have to change out every 1000 miles. go with the greddy egt gauge, its some good stuff

 

Why do you have to change it so often?

 

i have egt a/f and boost

 

i was gonna go with:
boost
egt
oil pressure
and anything else?

Motec PLM (professional lambda meter)...the best gauge you can have!!

 

why is that. the DIY kits run off the vx o2 sensor which lasts a lot longer than 1k.

 

i would skip air fuel meter and get oilpressure, elektronic fuelpressure, boost, EGT and something that monitors knock. Than you home free.

Maybe an oiltemp too

Or the lambda Option on your Motec

 

anyone know anything about the autometer auto gage line? they are about 1/2 the cost of the ultra lites.

 

You get what you pay for.

 

need to know exhaust temp so you don't melt your afterburner exhaust from AZ
JEes forkin noob

 

1 boost

2 egt


If vehicle is tuned properly at the dyno no need for a/f gauge. Keep it simple !

 

Theres a post in the room .. Greddy 52mm and/or 60mm EGT and Boost at a good price, you should look in to them. Im considering this buy also.

 

Boost/vac
EGT
oil pressure

 

Do the FJO, it responds faster than the Motec PLM anyway, I've used both and definitely prefer the FJO Wideband. Pick up the datalogging software and the display and you will never regret it!

 

i think a narrowband a/f gauge is ok for the amount paid, until i have more money for a wideband. You CANT tune with it but at least it lets you know to let off the pedal youre running lean, eg. if fuel pressure drops.

EGT gauges are not that great and i wouldnt consider them a tuning device either, there are many variables that affect it, for example advanced timing makes the temps lower, so you might think youre ok when in reality you are leaning out. retarding timing will make temps higher so you'd think you need more fuel and really just run really rich. cam profile, cam timing also affects the temps

 

I only have boost

I need a/f or exhaust temp.
