AFR & Tuning Zone / Re: Thundewrmax O2 Sensor Problem
« Last post by q1svt on Today at 03:58:12 PM »

q1svt, Checked wiring with a DVM, also checked for 12V on the data plug. My unit came as one assembled module, 340 and 350 already joined, that was how I sent them back to Tmax.

Thanks for the ideas.

Joined yes but they are not wired together... the autotune talks via the HD data connector, to the 32-36 ECU pin connector, then into the TMax ECU...

It's a four wire connector positive, negative, front o2 data, rear o2 data.

ThunderMax checked the units result good
You have switched out the o2's result should be good

But you get an error messages:
If not found = bad positive or ground w/HD wiring [data connector to the 32-36 pin connector]
If you get the fault o2 code it's either/both the front/ rear HD wiring [data connector to the 32-36 pin connector]

You have indicated that the problem is intermittent ... so look for corrosion/fraying @ both connectors you'll need to open them and check wire to pin attachment
OR just purchase a new data pig tail and install it into the 32-36 ECU pin connector.

I just noticed this thread...

What a coincidence, I tried to order an Exotx filter about a week or so ago.... Been on the fence for a couple years... finally decided to get one but I obviously waited too long.....

I got a PayPal refund and this notification from the Exotx performance team:


"Hi Bernie;

First, please accept my apologies in my delayed response Ė there were many unfortunate factors at play.

The details are long, but unfortunately, Mark, the owner of Exotx, has decided to close the business.   This was a decision process that started right around the first of the year, and the final decision was made late last week to discontinue production.   In the midst of all this, my father in law passed away after a short illness.   In essence, I was lax in responding to folks, and although that is no excuse, I hope that you can at least understand that certain family matters trump business obligations.

Regardless, Iíve issued a complete refund for your purchase through PayPal, you should have already received an automated notice.

Sincerely,
The Exotx Performance team"

Ajayrk,  brand new plugs, I keep an eye on them, change them at least once a year needed or not.

q1svt, Checked wiring with a DVM, also checked for 12V on the data plug. My unit came as one assembled module, 340 aqnd 350 already joined, that was how I sent them back to Tmax.

doubletrouble, I have cleaned and used D-grease on grounds and plugs. I can monitor the afr's as the bike warms up. There was one time when I got the message O2 sensors not found then the error went away. Hope you're wrong on getting bad new O2 sensors, those sensors aren't cheap!

Now exhaust leaks have me thinking about the time line when this happened. I had to remove my exhaust to replace the oil pump last year, and I am fairly certain I have them installed properly. Hummm... I'll have to check that.

Thanks for the ideas.

16715-83 - 5/16" x 18 x 24 x 1-11/16"

Check what part number they sold you if it is not 16715-83 then it is the wrong stud.

Did that, the nut side is 5/16-24 fine thread, on the stud that came out, the coarse thread size id 5/16-18, don't know what the thread pitch on the new HD stud coarse side that goes into the head, but it's not the same (5/16-18 that came out of my head). Aftermarket studs don't have the thread sizes listed.

Sounds like they gave you the wrong stud. Double nut the old stud to remove the stuck nut to ID those threads as well.
