Would you want to mount a round gage on the A Pillar of your Corvette? If you want to reference the AFR as you drive (especially under hard acceleration) it needs to be somewhere in your primary field of vision so as to not interfere with your driving and yet you don't have to take your eyes off the road to see it.Ģ. I'll be glad to help you with alternate suggestions for a permanent installation as I do this kind of thing for a living in my day job as an avionics (aviation electronics) engineer.ġ.
#Plx wideband o2 install java upgrade#
I'll upgrade the drawing into about a three skeet installation instruction in the near future. Look the drawing over and ask more questions. However, then you have to mount it somewhere and do more wiring etc. You can use a 20 Ohm resistor in place of an old Narrow Band Oxygen Sensor. Here's a simplified diagram that I drew up a few months ago to show the very thing that you're talking about. If the gauge is powered off, then I can always flip down the glove-box and look at the display on the WB controller. I wanted a configuration that allows for the WB to always run (and it does - it's on ignition-switched power w/ a relay), but for me to have the luxury of not looking at the gauge when I didn't want to. It's only the AFR gauge, and not the actual WB controller itself that is on the toggle switch. Thanks for the warning, but I've already got this covered. You may already be aware of this issue and have corrected for it, but if not, I thought you might like to know. I only post in the hopes of preventing an early failure of your sensor. Turning off the power while running your engine may shorten your sensor's lifespan. I am not intimately familiar with the inner workings of the sensor, or why this warning is placed, but I believe that it relates to ensuring that the heating element in the sensor has power and that the sensor is at the proper temperature. The installation instructions for my system indicate that the engine should not be run without power supplied to the sensor. I also own a wideband O2 sensor system based on the Bosch LSU4.2 sensor and understand the distraction created by the oscillating guage. I do however want to add one word of caution in regards to your power switches and turning off the power supply to the wideband sensor while driving at night. Special thanks goes to Ross (GMPX) and Steve Bryant for answering the many questions on the 'wide-band' thread! Cheers guys!
I've posted some highlight pictures here, as well, just in case anyone else wants to use this for ideas.
I had the car up on jackstands for a few weeks, as I did the whole job by myself on my back. Run wide-band and narrow-band outputs to center console for attachment to Flashscan controllerĮverything seems to work really well and I'm really happy with the install, even if it did take a good bit of time to complete. Mount PLX AFR gauge and shift-light in Autometer dual-pod on A-pillar Run all new wires for switched (and relay-protected/fused) power inside cabin and wire up the wide-band (and my shift light! :)) Mount WB on passenger side, but can swap it to driver's side (with some effort) by swapping the straight pipes from side-to-side Well gang, it took me a little bit to get done, but I've gone ahead and finished the wide-band install in my 'vette.ĭrop exhaust and weld in bung in off-road pipe for WB mounting
