RE: Installing an 02 sensor eliminator
I guess I don't need one since it would be inconceivable to ride my CB1100 around with the engine at 1500 RPM, lol. But I would strongly suggest doing a dyno run and get an A/F ratio chart to make sure the engine isn't running LEANER at higher RPMs, which is of course not very good for it. Not very good at all.

The ECU goes to a default map when you install this thing, it has no idea what to do, and cannot make changes in real time based on the exhaust.

RE: Installing an 02 sensor eliminator
Just installed full exhaust and installed the O2 sensor eliminator and bike runs better than it did with stock exhaust and O2 sensor installed.

Reflash the ECU? Or plug-n-pray?

The ECU goes to a default map when you install this thing, it has no idea what to do, and cannot make changes in real time based on the exhaust.

The following would suggest that the O2 Sensor does not provide real-time data to the ECU at higher RPM and that it is primarily to assure EPA compliance at idle and low RPM:
..........................................................................
How Does An o2 Eliminator Work?


The O2 sensor which is installed in the stock exhaust systems of motorcycles are used by the Manufacturer to adjust the fuelling in order to pass the emission tests for street homologation.

This is done only in a very limited RPM range under certain load situations. The intention behind it is not to improve the performance of the machine. It's aimed to reduce the emissions of the engine in the specific RPM/Load situations which are tested during the homologation process.

This can result in delayed throttle response or unsteady power delivery. If you replace your silencer or exhaust system or fuelling, it's suggested to remove the installed sensor and replace it with this eliminator.

The eliminator simulates the signal given from the O2 sensor under optimal A/F ratio conditions. This allows the bike to run under best performance conditions.

If you install an aftermarket exhaust, remove the catalyst, install a power commander or perform similar modifications we strongly suggest installation of an O2 sensor eliminator for the best performance of your machine.
........................................................................

Ulvetanna,

Do you have evidence to support your view and that the use of the O2 Sensor Eliminator WITHOUT the use of a Power Commander or ECU Reflash might be dangerous?...Because, there are a lot of CB1100 owners running these Eliminator plugs, and ALL have noticed a marked improvement in drivability. Are the typical PCV charts for the CB really adding much fuel in the upper RPM ranges?

No re-flash, and I am currently happy with the performance. Much better than stock and for some unknown reason, I feel less buzz in my handlebars; maybe the reduced weight of the exhaust?

Lol, I don't ride at that RPM very often but being in Seattle, there is usually traffic to deal with. It's easier to roll along at just above idle in stop and go traffic rather than work the clutch the whole time.

Gumby, this is my understanding as well after discussing this topic with my mechanic friend who previously worked for Honda in a fairly technical capacity. I brought it up as I was wondering how my CB would respond to variations in altitude when riding around mountains without the O2 sensor.

Exactly. If I wasn't using my bike for commuting, then this might not be as much of an issue, but here in Portland I deal with similar conditions on a regular basis. The difference the 02 sensor eliminator has made when commuting is not insignificant by any means.

RE: Installing an 02 sensor eliminator
Where I live elevation is roughly 4,800 ft. I ride in the mountains of E. Idaho and W. Wyoming (5K-8K) and in the Arco/Snake River desert and bike runs much better with the O2 sensor eliminator installed.

RE: Installing an 02 sensor eliminator
OK..so did everyone buy this from the UK EBay seller or is there a more local source?

Also, did anyone buy and install the blanking plug?

http://www.ebay.com/itm/o2-Oxygen-Lambda...GJ&vxp=mtr

This is where I got mine and it came with the blanking plug. However, I have not taken the time to drop my exhaust in order to install the blanking plug. There does not seem to be any way to remove the O2 Sensor from the stock exhaust without doing so, and it helps to have the removal tool or a modified socket or box wrench.

As for other sources for the Eliminator Plug, I haven't found one this side of the pond. However, if you contact Power Commander Customer Service, you may be able to order a replacement for what they call an Optimizer Plug, but you would probably pay more than the UK ebay version.
