i am looking for a air/fuel ratio gauge that can monitor both the left and right side and that is pretty cheap,i want to install a dual pillar pod,or the one that goes in my vent on my car and i found a gauge thats 2 inches and the pods are all for 2 1/16 or 2 5/8,anyone have any suggestions
Narrowband o2 sensors and gauges aren't really worth the cost. If you are looking to accurately see what each side of the engine is putting out you need to use a wideband, and for both sides you would need two.
If you are interested in tuning the car yourself than a wideband o2 setup and something like the tweecer is a good idea, but for everyday purposes it hardly worth the cost.
Unless you have a compelling reason, put your money towards an oil pressure gauge or a fuel pressure gauge.
well i was wondering about the air fuel gauge becuz i had seen one at oreillys that was a iequus or somethin like that,and it was only $30 and it had a gauge for both left and right side.i was curious about it.
I would agree with putting the money towards a WB or other parts. If you really wanna do it, you can use one gauge for both banks. You'd have a switch to toggle between the banks. Having only one guage saves money on aspirin (the flashing lights are annoying IMHO).
The A/F gauges that use the O2 sensor signal will jump all over the place. The reason is that the O2 sensors "switch" between
.2 volt lean and .6 volt rich with a curve that looks like the drop off a high cliff. The curve is almost straight up and down, so the
voltage shoots from .2 to .6 and back down . again 2 or more times a second at cruse. You won't get much useful information
except when the mixture is extremely lean or extremely rich, there is no middle ground.
If the idea of a useless light show still sounds interesting, here's how to wire it up...
Use 43 (Dark Blue/Lt Green wire) or pin 29 (Dark Green/Pink wire ) on the computer. Use Wire tap-ins from Radio shack P/N 64-3052.
The computer is located under the passenger side kick panel. That keeps you from having to crawl under the car and make a weather proof splice in the wiring. You can use either one, or run a SPDT switch and use both. Then you can use the switch to select which side to view.
