PLX install completed in preparation for Flashscan!

[AllCammedUp]

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.

Here's a summary of what was done:

• Drop exhaust and weld in bung in off-road pipe for WB mounting
• 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
• Run all new wires for switched (and relay-protected/fused) power inside cabin and wire up the wide-band (and my shift light! )
• Mount PLX AFR gauge and shift-light in Autometer dual-pod on A-pillar
• Mount PLX controller in glove box
• run wide-band and narrow-band outputs to center console for attachment to Flashscan controller

Everything 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. I had the car up on jackstands for a few weeks, as I did the whole job by myself on my back. I've posted some highlight pictures here, as well, just in case anyone else wants to use this for ideas.

Special thanks goes to Ross (GMPX) and Steve Bryant for answering the many questions on the 'wide-band' thread! Cheers guys!

Mount PLX AFR gauge and shift-light in Autometer dual-pod on A-pillar. I installed toggle switches on each one so I can turn off the shift light or the AFR gauge when I don't want to be bothered by them. The shift light isn't such a big deal, but the AFR gague has no backlight and no contrast adjustment, so it's constantly osciallating while the car is running, and at night, it'd be nice to not to have to look at it.

PLX controller in the glove box - all nice and snug and out of plain sight.

Additional wide-band (blue) and narrow-band (red) outputs run to center console to be hooked up to the Flashscan interface once it ships!

I think that at this point, I'm ready to do some serious logging and tuning!!

did you use the LSU4 sensor? if not what sensor is that?

i'm looking at buying one of the DIY kits with the LSU4 sensor

Whitney,

Your installation looks really nice. Excellent job!

Thanks for the responses, guys! I just wanted to get something out there for others to see, as this isn't your 'typical' mod, and I thought the pictures might help others if they attempt the same thing.

Dissonance - Yes, the sensor is a Bosch LSU4.2 wide-band sensor. Here's the actual unit I bought:
