a:f gauge
i'm thinking about getting an air:fuel ratio gauge or something, but i was thinking, i don't know what to do if says i'm running too rich or too lean. Having the gauge would be pointless if I couldn't do anything about its readings.
the only engine mods my car has are a nearly straight thru exhaust and an intake.
i'm looking at the three things at the bottom of this page:

i'm not really sure what they all do. I just want to make sure my car is not running too rich or too lean. I've heard that running lean will damage the engine.

oh, good. i don't really want to mess with that stuff my self. i would probably screw something up.
Any other gauge I should consider getting? My stock gauges seem to be working fine, but I'd like to keep my motor in good running condition.

if you want to get some gauges in your car to feel safer get oil temp oil pressure and water temp, and if you have a turbo a boost gauge. imo those are the only ones that you would want to get with a stock, or slightly modified car.

For an NA.
The only aftermarket guages you'll need are
Coolant (BIGGEST PRIORITY)
Oil/Temp/Pressure(iffy. You can live without it)
For Turbo.
The above along with Boost gauge with vacuum reading as well.
Narrowband AFR's are pretty much just pretty to look at. They can't do a whole lot. You get an idea of what your doing but cant tune by them.
Wideband AFR gauges are awesome. You know exactly where your at.
NA cars don't have any tuning issues other than their known to be a bit rich. Leave it be and have a trouble free car.

good job, best way to do it is suspension brakes and tyres first, then work on power
btw, what are good brands of gauges and places to get them?
rx7.com has greddy gauges, but they're really expensive. autornd.com has some universal gauges that might work.

you need to have your os sensor plugged in and working it makes your car run 1000000x better.
for right now i am getting autometer pro-light gauges. they are the cheapest and the lightest gauges that autometer sells. until i can afford better gauges, or i get sponsered i will use them. they arent as acurate as the more expensive gauges out there, but they do the job better than the stock sutff.

You won't be tuning by a narrow band A/F gauge, but it is a very useful thing to have. It will tell you if you are in closed loop which helps you save fuel during cruising and verify that the stock ECU is working properly. It will tell you if your emissions sytem is working properly (should read full lean at idle), and it will tell you if you are stupid rich or stupid lean. With the addition of a vacuum gauge you can learn a lot about your engine.

I guess my emissions weren't working cuz my idle would be really rich on NB a/f gauge (then again I didn't have an air pump, don't know if that affects it).
Is it good to keep the narrowband gauge even if u have a wideband?
Also wat vac do u guys cruise at? 10"?
