Making an o2 sensor voltage monitor...

[16G TSi]

What are you guys using to keep an eye on o2 voltage? I see alot of people are using the Jumptronix monitor, but thats ~$100 for what is about $2 worth of parts from radio shack.

I had a rat shak voltimeter hooked up ($16.) but its not back-lit so you cant see the readings at night......


Any suggestions welcome, links to a site with a how-to would be great.

can you see the results of the pocket logger in "real time" like with a voltimeter?

what I'm reading about most loggers is that you get a read out AFTER a certain predefined amount of time.

Thats great if you want to burn a piston then go back and see why..... i want to monitor o2 voltage in real-time.


Dont tell me all of you just buy stuff for your cars at stupid prices and dont consider a little enginuity? Surely someone has made their own voltage meter from a 5 digit LCD screen and some resistors?

:D :D :D :D


awesome, thats exactly what I was looking for!!!


thank you soo much. I plan to add step-by-step directions to this thread, or a new one so that people of this board can do it themselves. I like the fact that the jumptronix meter exists, but I dont like the price, considering that is all of, what, $3 in parts?


Thanks again man!!!!!!!!!!

well, that sux. Radio shack doesnt carry the digital voltage/panel meter anymore..... The next cheapest I can find is $147 :rolleyes:


Oh well, looks like I'll be getting another pocket multimeter....:mad:
