Thread: FS: DHP Tuning Setup (Laptop, DHP, PLX WB O2)

Done

Noob question, I assume you have to add another O2 bung for the wideband? Or can you remove pre-cat O2 and insert wideband just for tuning?

and do you have a gauge for the wb or is it for direct hook up to the laptop? curious about the cable off the plx box there. how does that work? im still trying to get mine to read right on a scan.

if it is like my wideband, on my wideband there is a serial output/input cable so if plx has software, you can see what the gauge is reading on your computer. on mine, you can also program the gauge itself, like speed up or slow down the data rate, or change the colors that the gauge shows. the serial output is really only useful for programming because you can't incorporate any other data to display with it.

I do not have a the gauge, I just had the serial cable connected to the laptop via usb. Steven Chesser had made a version that allowed the direct serial connection with UVScanII back in the day. It worked much like the direct connection he did with the Innovate WBs. That's what's installed on the laptop.

I believe the guage you are talking about hooks into the headphone-style port on the PLX box. This is also a serial style communications. It just sends the AFR data bits to the guage for display.

Its in this thread somewhere...lol..start on Page 9: https://forum.efilive.com/showthread...Serial-upgrade
You're just tapping power, ground and signal. I can open the box and take a pic on where I hooked it up.

This looks like it might work (its a later post in that thread): http://www.ebay.com/itm/200983912175...%3AMEBIDX%3AIT

Here's pics of the modification. Feel free to move all of this to a new thread.





The zip tie is for strain relief on the cable inside the enclosure.

I can add it soon. It's got a bug with the grid to guages feature but doesn't impact scanning and logging.

So the community DB is full. I shared a folder/file with the Community DB from my DB. You can find the PLX version (UVSCAN2.0-61209A-DirectPLXSMAFR.zip) under the Share section. (https://www.dropbox.com/share)

You'll need to go to the Setup menu tab in UV to tell it what com port the PLX is hooked up too. The PLX Direct PID is under the Fake PID -> PLX AFR WIDEBAND DIRECT. It's hard-coded to 14.7 AFR scale.

In DB, navigate to Sharing then to the Files tab. The file link is there.

Still for sale? I work in Grayslake interested in the set up.

Yes. Shoot me a PM with your info.
