PLX Screwing Us Again
 

This has to do with their "style of Bosch LSU 4.2 sensor".
Many years ago they used the one with the round connector listed as Older.
My first M300 had a cable that fit the old style sensor. Bought it around 2000.

Then in 2010 I purchased the newer /faster "M300 Tuner" WB which used the Newer version of the sensor.

My sensor went bad recently so I just ordered a replacement. It arrived and it is the older style which does not normally fit the newer style cable. I called and they informed me that they changed back because it is cheaper. Cheaper for a connector style? Then they tell me to buy the older cable so it would fit. Frig that , and from buying from them again.

If you take off the little locking piece of plastic from the newer male connector on the cable, it will fit into the older style female connector on the sensor. Just be sure to get the orientation correct else you will be 180 degrees off. Then tape it together for when you test.

This way you do not have to buy another cable or the costlier newer sensor.

Chuck, have they screwed people in the past?

I'm not a fan of their gauges after installing a bunch of them in a customer's FD.

there's only a few widebands i trust, and PLX isn't one of them.

in fact i trust my techedge over anything else, regardless of a certain someone who was banned from this board's hate of them. this thing has been through hell and back and still keeps kicking, still tunes to the ragged edge even being 10 years old and having touched countless cars. NEVER have replaced the NTK sensor it came with, the threads are starting to round off... leaded race gas, ethanol, water/methanol injection, pump gas, daily driven 30k+ miles, oil spit from fresh engines, it's been through it all.

i also need to resolder the display, getting tired from being banged around so much but trust is something earned and i won't replace it until it dies. i have never seen any other wideband take the abuse this has and still function on a usable level.

one day i wired it up reverse to the battery, blew the fuse and i was a little skeptical that it survived. popped in a new fuse and it of course went back to work as usual.

my version has long since been retired and i do not know if their current ones are as reliable.

They are still kickin..

WBo2.com WIDEBAND AFR/LAMBDA (Tech Edge)

i know they still build units, mine is old school though and a basic box with just a serial dongle for logging. hacked into it to log directly to the datalogit for the FD/FCs.

i do wish it had a narrowband emulator though, for those POS microtechs.

This doesn't suprise me, years back PLX screwed people with the r500 widebands including me. They made the unit firmware upgradeable, and after many bugs were identified they made many promises but they never delivered any firmware updates. All the complaining went to deaf ears, and found out they dropped all support of the r500 because of a "newer" wideband coming. Although some of their marketing hype is cool, their support isnt there. I never bought another plx product after that, and never will.
