Default Yes, O2 sensor question.

Is it really worth disconnecting the o2 sensors on my ‘16 Magnum?

I was planning on clipping 2 wires and leaving the heater circuit intact. Will this do anything? How bad will it affect Fuel mileage? I currently only get at minimum if about 215 miles(depending on wind and other environmental factors) .

Model year '16 introduced the new 02 sensor wiring = If you unplug them, the "check engine" light comes on. I am unaware of a way around that, outside of a piggyback fuel controller or other tuning device. It's a bummer for sure.

I have not touched the O2 sensors on my 2011 cross bike since I bought it new. I get around 40 mpg riding the twisty roads around here and I have more than enough power. 215 miles on a tank would be around 40 mpg if it is near empty and better if it is not.

to prevent having a check engine light you need this. One per 02

I pulled the O2 connections on my 13 and added a timing wheel. Bike runs wayyyyy better.....

I have a new 16. The worse thing I could do is pull or plug those. When I get into the performance I will get a new 2018 Tuner and the 02 sensors will stay. Removing cats is also a dumb move to make on a Magnum or XC.

The bypass mentioned by VJ plus a Lloydz timing wheel and a higher flow air-filter is the poor man's (or cheap bastard's) tune up. The BEST choice is a maximus or a scab-over tuner and a dyno tune. Of course that's about a $1000....... Oh, and you NEED a 1/4 turn throttle ring....there are other "upgrades like cams and exhaust but.......$$$$.....LMYR

Long may you ride!

I'm the 'cheap bastard' that's trying to run without O2 sensors until I can get it in for a tune. I just installed the Dobeck bypasses and I'm still getting a check engine light. What gives?

A 1/4 turn throttle ring isn't needed. It's a personal preference.

It doesn't increase performance, it just reduces the motion needed to operate the throttle. I had one, and ended up removing it. I like a little finer control of the throttle. The 1/4 ring made it a bit jumpier for me.

If you spend all day going WFO, it might be for you.
