O2 sensor eliminator?

I bought a 2006 Dyna this summer, stock except for Screamin Eagle II mufflers and K&N air box. Original ignition and EFI systems.

I need some help. I want to do a low budget job to get rid of a hesitation just off-idle and have a cooler engine too ( I burned a hole through the right leg of good winter pants at a red light on the last ride this fall).

I was thinking of just doing a O2 sensor eliminator job, nothing else.
Will it work? Is it enough? Will my engine run too rich at idle and cruising?

Can someone give me clear answers?

Thanks

You are going to need a tuning Device .just using 02 eliminators will cause you more trouble than you have now. You need a tuner that allows you to take the sensors out of the mapping Strategy.
Just eliminating the sensors without taking the system out of closed loop within the ECM,will cause it to go leaner than it is right now.
And if you run into the XIED's in your quest for doing this?
Sooner or later someone will suggest them.....they are just a waste of money that you could apply towards a tuning device that will actually do what you want .

I do agree with strokerjik,

MY choice for the fueler IS Dobeck, EJK controler. TFI or a Gen3 will do the job giving you the tune-ability. It WILL allow you to Un hook the 02 sensors and Dobecks fueler will add the necessary COOLING Fuel needed...
Dobeck is a paid contributor on this Forum and DOES give you a member discount.. Click on the ad to the left of you page saying EJK.

I have done BETA testing on Dobeck tuners and they DO have a fine Inexpensive product for our bikes. They WORK....

I must say... I have one of the early Dobeck devices on my VRSCSE2 and it REALLY makes the bike more pleasant to live with. I can only imagine just how much better their product is today.

Many thanks for the answers.

I was about to buy a XIED part, but I wont.

I will follow your advice and buy a tuning device, according to your recommendations.
So now, I will give a look at these systems and choose the one I prefer. But Dobeck seems to be a good choice.

Thanks again

I seriously doubt the O2 sensors have anything to do with your problem, especially if the problem happens when the motor is cold. The computer ignores the O2 sensors when the motor is cold.

Also, Im not sure how the o2 sensors make your motor hotter. That would suggest that your motor is running lean if it is too hot. Removing the O2s wont fix that. A better tune would help there.

Id suggest diagnosing the problem instead of guessing. Id start by getting a spark tester and making sure you have adequate spark (not just the existence of spark, but good spark) when the problem occurs. If the problem is the plugs not firing correctly, then look at the coil pack.

I dont know if your bike has a Schrader valve or similar to check for fuel pressure, but your fuel pump could be getting weak and not providing enough fuel and/or fuel pressure. See if you can hook up a fuel pressure gauge (available for rent at most auto parts stores) and check for proper fuel pressure.

Good luck...
