So this morning before I went to meet ACKCB, I pulled the right-hand side-cover and found a 4 pin connector that matched it elim. Started the bike and rode to meet ACK. The sputtering seemed to still be there. What I didn't notice right away was that the spedo wasn't working and the ABS light was on..... We stopped in Sconset and "Thank Honda" for the right allen wrench in the "Tool Kit" and I pulled the cover to remove the Elim and ACK noticed that there were two 4 pin connectors, so we swapped it out. Same result ! No spedo and didn't go far enough to see if the sputtering had stopped. Removed the elim and all was back to normal. Does anyone have a repair manual for the DLX. Is it possible that there is another 4 pin somewhere ? Or maybe this just dosn't work on a DLX ?

Since you have two O2 Sensors, I would think that you need two Eliminator Plugs. Can you borrow a plug from someone to test?

I thought of that, but why would the spedo and abs go off ?

Bike electronics can do strange things when there is an open circuit or if conflicting data is received from one of two circuits that should both be receiving similar data.

According to the parts chart, the DLX is supposed to use the identical O2 Lambda Sensor, but in two places. In theory, doubling up the Eliminators should work...but the DLX may be an exception.

It would seem to me that as long as the circuit sees what it believes to be a lambda sensor, all should be okay. Could the sensor eliminator be defective? Should be easy to check with a Triplet meter. Could you compare the ohms resistance across the leads on the Lambda sensor with the new plug? I've not looked at the Lambda connector, but some types can get the contact pins pushed back inside the connector plug. Has this been checked?

Not sure i'm qualified to do that, I have a meter. I'd like to see an electrical schematic. Or see what a service manual says. At this point i'm just happy I didn't screw anything up.

Next time your downtown I have a Fluke meter here, we can check it.

My sensor eliminator came in the mail during this discussion so I immediately installed it and took the bike out for a 20 mile test run. Everything normal and the motor does fuel better at low rpm's now. I always thought the CB had good fueling properties for a FI bike but now even better-more like my Guzzi that was smooth as a carb motor at any speed. I also noted that the speedometer sensor and the O2 sensor plugs are side by side inside the same clear plastic cover on my 2013 but slightly different looking. Is this the case on the 2014 DLX?

Chapomis, did you chase the wire from the o2 to the plug? My plug was black, right next to a blue one. I assume you need 2 eliminators anyway but I just don't understand why your gauge was messed up.

Also my bike should be on the dyno sunday so we'll see how it is fueling with the eliminator.

So had my bike on the dyno. With the o2 sensor at low speed it was lean, around 15.5:1. It surged and hesitated on the dyno and standing next to the bike when he was running it I could see it. With the o2 eliminator installed it ran smooth as I stated before, but because I had it flashed and richened twice it was running pretty rich, as much as 11.2:1. So I want send the ecu back to guhl and have it leaned to where he originally had it. But what I dont know is will the eliminator always keep it that rich? Any thoughts?

That's what I was lead to believe. It makes the ECU run like the bikes cold all the time, full rich. That was the reward I got from mine.
