Up early this morning~
I was originally planning to go to Taste of Tsukuba tomorrow, but the weather looked iffy so I changed my plans.
So today I was installing the PE Wideband O2 Controller Kit~ <\/a><\/p>\n\n\n\n

<\/p>\n\n\n\n\n\n\n\n

\"\"<\/figure>\n\n\n\n

The setup is extremely simple.
Sensor connector, 12V power, &and ground only.
Data transmission is via Bluetooth. <\/p>\n\n\n\n

If you set it to auto-connect on the app side, you can connect by launching the app and selecting the sensor.
*No need to press the unit itself every time (\u03a6\u03c9\u03a6) <\/p>\n\n\n\n

Pre-machined O2 sensor adapter M18\u00d7P1.5 <\/a><\/p>\n\n\n\n

I picked this up on Amazon the other day\u2014a gem? I wasn’t expecting much, but it’s very good.
No time to make anything else… <\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

There are surprisingly few places where you can mount the sensor…
So when I drilled a hole in the sweetest spot… it looked weird.

The tail pipe is also acting as a silencer… isn’t it?
I’m amazed at how good the stock muffler is. <\/p>\n\n\n\n

This sensor boss has excellent weldability\u2014I was impressed~
I’ll order it again (*’\u25bd’) <\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

It’s tight, really tight.

I positioned it to clear the center stand and laid it out in the middle box-like area of the swingarm. <\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Glad I was able to get it installed! <\/p>\n\n\n\n

Hmm… the cover keeps opening… seriously??
So I fixed it with Megmix. Now it’s secure? <\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

It’s now sitting in the rear area under the seat. <\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Connected to 12V power and ground from the D-UNIT. <\/a>

*By the way, I went with the standard D-UNIT this time (\/\u03c9) <\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

After that, just plug in this big connector and download the app and you’re done.
PE Wideband App for iOS <\/a><\/p>\n\n\n\n

PE Wideband App for Android <\/a><\/p>\n\n\n\n

\"\"<\/figure><\/div>\n\n\n\n

It displays with good response like this. <\/p>\n\n\n\n
