ilanr1 Posted April 12, 2020 Share Posted April 12, 2020 Hi , i have tracer 900 with full system Arrow no cat , 2015 model. Can i remove the lambda sensor and place a blank cup instead ?. Your advice please. Thanks Link to comment Share on other sites More sharing options...
BBB Posted April 12, 2020 Share Posted April 12, 2020 If you simply remove the O2 sensor you’ll get an error code. You have two choices: - get a blanking plug that clips into the wiring loom, instead of the O2 sensor. These have a set of resistors built in that fool the ECU into thinking the sensor is still there. Example Yamaha FJ-09 Tracer 900 O2 Oxygen Lambda Sensor Eliminator Complete Kit Kit contains O2 sensor eliminator with rubber end cap and a M18x1.5mm... - or get your ECU flashed (which then ignores the O2 sensor). Then you can remove the sensor and fit a blanking plate in the exhaust. I presume there is a third route of pulling the O2 sensor out of the exhaust and tucking the whole sensor/wiring somewhere under the seat, but I don’t recall anyone doing this and I have no idea if it would work.

ilanr1 Posted April 12, 2020 Author Share Posted April 12, 2020 Hi , my thinking was at first just to pull the lambda sesor out of the exhaust and cover the hole with a blank cup. Later to make my own plug from the old lambda's plug , to measure the resistance on the wires and to solder the right resistor instead.

It comes with everything you need in one package for a couple of bucks. ***2015 Candy Red FJ-09*** Link to comment Share on other sites More sharing options...
BBB Posted April 12, 2020 Share Posted April 12, 2020 Resistor values here. Funnily enough, from your last thread on the same subject 🤪 . Red 2015 Tracer, UK spec (well, it was until I started messing with it...) Link to comment Share on other sites More sharing options...

Timely post... like the cleaned up look of the O2 port on your bike, so I ordered the plug. Sensor input is "disabled" in the flash, so hopefully ECU wont throw an error code when I unplug the thing, but if it does... I will rig up a dongle.

My tuner supplied a blanking plug for the connector where the O2 sensor wiring entered the main loom. I removed all the wiring and cable guides from the right hand side of the bike and then just put the blanking plug on. I’m sure it’s just a dust/safety cover though, no intrinsic functionality. 1 Red 2015 Tracer, UK spec (well, it was until I started messing with it...)

I have a 2017 Tracer with a full Akrapovic carbon system, I installed the lambda sensor into the pipe and the bike runs great. Link to comment Share on other sites More sharing options...
ilanr1 Posted April 13, 2020 Author Share Posted April 13, 2020 (edited) Hi , if you don't have a catalitic converter why do you need this lambda sensor ?. It's useless... Edited April 13, 2020 by ilanr1 Link to comment Share on other sites More sharing options...

My tuner (and several others) disabled the sensor input to be able to better control AFR and smooth out the throttle response... so the O2 sensor on my bike has since become a glorified anchor point for the slip-on.
