Harness jacket sealed to sensor and secondary jacket zipped up tight.
The top of the O2 sensor is also sealed.

[porthole]

What is this piece in the center?
Now I am wondering is this is a ferrule to allow wire tying up tight without collapsing the jacket.

[porthole]

The jacket is definitely sealed to the sensor.

Yes, all O2 sensors draw air in through the wire harness area. Those are a Bosch LSU4.2 Broad Band sensor and they have been modified, which Bosch recommends against doing. While I can't say anything about the modifications what I can tell you is that when the plug was cut off the end and replaced, they cut out the trimming network that Bosch had in it. Each sensor that Bosch makes of this model gets tested and then trimmed in for proper calibration. The trimming is done and placed into the connector and this is why Bosch says DONOT cut or modify the O2 assemble but you've got what you've got.

These are the sensors supplied with the RP EMS kit.

.....and we may have just learned something.  The Bosch sensors as supplied from the manufacturer are a calibrated piece.  Revolution Performance modifies them.  This we already knew. 

The EMS kit, distinct from TTS, TMax, PC et. al; requires calibration of the sensors local to the kit they are installed with.  It also has onboard hardware to simply and quickly do this.  Now we know why this is so.

So, in the end, no drama at all.

Would be interesting to hear a reply from RP regarding this and their modification. ??

The problem Duane is correcting here is with the bung rather than the sensor itself.  So not sure what RevPerformance could add.  Not intending to speak for them.  It's just an issue with another part.  The bung's issue admittedly would keep the sensor from working optimally.  But it's not a sensor issue per se.

Really? So Bosch says do not do it and Rev buys a kit from DTT that says the trimming network is not needed. I'm sorry but I will stick with what the people who developed and designed the sensor say to do with it. It's also nice to note that Bosch also says that you need to use the trim network to properly adjust each sensor to get correct readings in all of there documents and with out it (trim network) there is no specification on what the accuracy of the sensor will be. If you really believe that these guys know more............
I would be willing to bet that Bosch could save a ton of money by not hand testing each and every one and adding the trim network to them, yet they still do! Each and every auto manufacture that uses these uses them with the trim network in place too, guess none of them know what there doing.

Steve, as has been suggested before if I want advice on your product I'll ask you.  If I want advice on someone else's product I'll ask them.  Your predilection toward narcissistic self-aggrandizement at the expense of anything mentioned in competition is too regularly illustrated.  Don't need another example. 

So, if I want information on any of the details of the EMS product I'll ask Brian at Revolution Performance.  Or will rely on my own experience with the product on a couple bikes here in concert with the support from Revolution Performance.

Guess I could save a step and ask them for insights on your product and services als...... oh, wait, that wouldn't work.  They've proved to be a gracious enough people with enough customer service insight to know it's counter productive and rude to talk about the competition in public just to jack yourself up.  Their insecurities are (apparently) about the size (or even less) of the material Duane had to shave off that exhaust bung.

You were doing so well too.  Suggestions to Duane previously in this thread that stayed on point without too much patting yourself on the back nor real ridicule of the competition.  Had seem a couple of other similar instances lately also.  Old habits really die hard....

[glens]

Judging by that response I'll have to guess that you and Steve have some antagonistic history?

Steve may have in the past done/said stuff such as you suggest, but he sure hasn't done it in this thread.  At least not that I can see.  If one didn't already know, they'd have no idea by anything he's said here that he markets a product that could considered to be competition to the kit in use as the subject of this thread.  Right?

How does the EMS kit calibrate the sensors' closed-loop controllers?

That'd be my guess.  I'd also orient the connectors so that the jacket on the sensor lead doesn't collect water into a trap, however it may be that it breathes through the leads (either along the outside or through the length of wire inside the insulation).
