Ultragauge help

Hey TW,

I bought an ultragauge while ago and I was wondering if anyone could get the ultragauge to read AFR #'s? What other gauges and settings do you guys use.

Thanks

 

That is what I thought but I don't really know much about the UG. I just installed it. I thought you could change the settings to show it like an AFR gauge (10-16 range)

 

Bump. I'm curious to see what other UG users have their UG set to.

 

Sorry for the newb questions but I'm more interested in the "performance screen". The temp for the cats just tells how hot the engine is running or detonation? What does the Timing mean (what is normal)?

Thanks again for explaining.

 

You can monitor the lambda value with the Ultragauge. Lambda isn't a true AFR, but rather a relative one. The ideal stoich ratio of 14.7:1 is expressed as a decimal value of 1.0. You can tell if you're running rich (<1.0) or lean (>1.0), but you won't be able to tell the AFR unless you're back calculating the whole time. For example, if you're achieving an AFR of 13.2:1 (rich), then take 13.2/14.7 and you'll get a lambda value of 0.89, and vice-versa (0.89*14.7=13.2).

I had lambda on my UG for a little while, but it didn't really tell me much because it changes constantly and quickly. I wanted a bigger picture, so now I monitor long term fuel trim instead.

Edit: here is what I monitor on the main page of my UG
1) rpms
2) engine temperature
3) timing advance
4) engine load
5) long term fuel trim
6) battery voltage

 

Thanks to the people who chimed in.

Just a couple of more questions for you guys or girls.

Ecoterragaia - thanks for the awesome explanation. What is that lambda gauge called? Sorry for the newb questions but I'm still getting used to it.

What units is the UG defaulted to? When I was entering the fuel tank size I didn't know whether to put in imperial gallons or the other one.

Thanks again for all the help. Greatly appreciated.

 

Another question for you guys. How do I change the rpm alarm? It is soo annoying when it goes off at 4K.

Thanks in advanced.

 

Thanks! I bought mine new and it didn't even come with the manual .

Do you guys have your alarms set to anything? I changed my rpm back to 5500 and turned off the speed warning alarm.

Thanks again to everyone who chimed in!

 

Can someone please enlighten me on which number I should input for my gas tank size?The manual has 2 different gallons, 17.something and 21something.

Thanks again.

 

Bump!

 

Ya but is shows U.S. gallon and Imperial gallon. Which one should I input?

 

Thanks

 

Cant wait to get mine!! Just ordered yesterday

 

I have mine showing intake temperature, instant MPG, average MPG, battery voltage, distance to empty and I forgot what else.

 

Our trucks dont have a fuel sensor?
I didnt realise i need to reset the fuel everytime i fill up.

 

That's true but it only takes a second to reset.
