Hi, So I got the tuneboy map and I want to get a couple of windeband sensors for auto mapping, tuneboy manual says they offer the kit in their website but I don't see it in stock, anyone knows how to get that adapter from the picture and/or how do I connect the 2 widebands to the wiring loom?

Thanks!

They include an adapter to go from the device the wideband plugs into to the OE oxygen sensor plugs.

It looks like this. The bad part is there's a .... ton of wire to hide if you want to keep them installed on the bike.

Sorry, that pic didnt come out right. The Tuneboy kit isn't anything special, its just off the shelf stuff. The only special part is the software to allow you to map and write to the ECU.
 
I have the software, wifi module and key already, got the tuneboy base trim flashed already but I want to bring the bike to a dyno for fine tunning but I'm not sure which wideband kit and/or cables I need to buy.
 
That would be great thanks, or if you remember just what I need to buy, not sure if that kit from ebay has everything
 
My apologies, going through old threads here I realize it was more like 2015 and I should have given you better info. It’s nothing more than the LC-2 kit and a connector to plug into into the DDS OBD-II plug under the seat. I don’t remember what the pin out is, but I don’t think it would be hard to figure out.

There is also some good info here:

LC-1 wide band oxygen sensor install

I have just finished installing 2 LC-1 wide band O2 sensors to compliment my TuneBoy setup. Wideband sensors will be necessary for many tuning options not just the TuneBoy. There was a bit more to it than I had hoped so I'll leave some bread crumbs here for anyone that wants to follow down the...

I had a bitch if a time getting it to work but I’d hope in 7 years the software for better.

Here is a pic which show where the added connector is

Tuneboy doesn't sell them anymore. If you order on the site you'll get a refund. I discussed this with Wayne and he said he'd remove them. I got the LC-2's from another dealer and the AMP SUPERSEAL 1.5 SERIES 4 WAY connectors, then they can plug directly into the oem O2 connectors on the harness. Only get the 3ft cable on the sensors or you'll have a hell of a time stashing the cables.
 
Do they plug into the stock O2 sensor cables? I honestly can't remember. Back when I had it they sent 8' cables which was a mess to deal with.

Out of curiosity, why don't they sell them anymore?
 
They do plug into the stock O2 harness plugs.

He didn't say why, but did explain how to wire them up:

On the O2 sensor plug.

Pin 1 is the output on the LC-2 (yellow wire), can also use brown wire.

Pin 2 is ground.

Pin 3 is power, this should be used to power the LC-2.

Pin 4 is unused.
 
I ran into the same issue recently and he pointed me to the below items....

"I am not selling these any longer.

You can buy a wideband kit from ebay etc.

Zeitronix ZT-3 Zeitronix Zt-3 Wideband Air Fuel Ratio Meter plus 4.9 Oxygen Sensor AFR O2 USA | eBay

APSX-D1 WB D1-DIY Wideband Air Fuel Ratio Controller Kit - no sensor | eBay


The APSX-D1 is a kit and you need to buy the sensor

Hope this helps you!

I'm impressed with the DIY kit price, which one did you get? Do you know which bung or adapter needs to be used to fit the wideband sensors? I think they are 18mm

I have not tried this yet however when I do I will likely just go with the Innovate LC-2 kit as I know that is what many others have used so at least there will be some group support.
 
I'd get new bungs welded in so the probe is in the gas stream. I haven't seen a side by side test on the accuracy of the probe in those adaptors. After spending the money and effort getting the system in, a few bucks to make sure you're getting the right data seems a good investment.

This thread shows how I located the sensors: Wideband sensors / termi exhaust location
