has anyone used a air/fuel ratio gauge yet? i need an idea for a 3rd gauge

Jfaulkner

Those are for gassers to help show detonation. Won't work on a diesel (no o2 sensor). For a 3rd gauge (not sure what you have now) fuel pressure, transmission temp (auto trans). Turbo backpressure, boost air temp, 2nd pyro for either post of pre turbo depending on what you have now. The list goes on.

a/f sensor isn't a necessary item on a diesel engine. the a/f ratio on a diesel can be anywhere between ∞:1 to 10:1

You have EGT and Boost, I would get a FP next.

If you get a fuel pressure gauge make sure it's electronic. Do not under any circumstances get a mechanical gauge. I know someone on here will say that theirs is working fine, good for you! I have yet to see an isolator that is any good. It's not worth the hassle, wire up the gauge and run one wire to the sending unit and your done. No isolator to fill, no hose bleeding, no leaking.

Dude how did you type the infinity symbol?

Yes good for me. My isolator is fine, i have no leaks and didnt consider it a hassle at all.

A lot of guys that run mechanical gauges don't run an isolator, just a needle valve they can close slightly to dampen the pulses, and close incase of a leak. And I don't recall hearing of one leaking.

Open word....From the file menu...Insert, Symbol. Look for whatever symbol you want....

Then copy & paste!

Oh, electric gauges are the only way to go, for all the reasons stated above!

A friend of mine did the same thing after his isolator took a crap. By the time you buy the valve and the extra fittings and still bleed the line you could have had an electronic one.

Good luck with it. I had one for about a year before mine started leaking. Then I had to refill it and re-bleed it, never again.

Sweet! Learn something new all the time.

Hmm. So far so good. If i start having issues down the road i guess ill look into it.

I personally prefer mechanical to electrical where I have a choice.

to get ∞ and other symbols, you can use the extended characters on the keyboard

or in windows..
