Power Commander V on DLX

[Chapomis_imp]

Has anyone here added a Power Commander V to a DLX ? I'm pretty clueless in this area, so be gentle. I was talking to my local metric mechanic and he asked me if I "re-mapped" when I added the slip-on mufflers. No was my answer. He thinks I should. My concern is that most CB1100s are standards, so does the available PC work on DLXs ? I tried to add an o2 eliminator and it killed my speedometer and various other functions. The o2 sellers had no clue why it didn't work on a DLX. There be my concern. I searched " power commander, DLX" but came up with zip. Popgun ?

Everything I have read leads me to believe re-mapping is not required for slip-ons. However, I don't remember anyone replacing both on a dlx. I have no idea why the eliminator didn't work. I don't know why you would need it anyway?

I don't know anything about Power Commanders so can't help there.

As far as the O2 sensor you need 2 eliminators for the DLX.

Also, looking at the schmatic, the both front and rear speed sensors go into the ABS modulator.

The O2 sensor has a 4 pin connector. IIRC one member wanted to install an eliminator, but leave the sensor in, with the connector plugged on it for weather protection. So he tried following the cable back to another connector and plugged the eliminator in the wrong circuit. And his speedometer stopped too. Did that happen to you by any chance?

One wire of each O2 sensor goes directly to the ECM. I didn't follow the other 3.

Acording to the fault list, an 02 malfunction shoule result in a check engine light and MIL code . It says Engine operates normally for all the 02 malfunctions.

Unless you did something not right, I'd put everything back to spec and see if all works correctly. They add the eliminators to the O2 sensor plugs and see what happens.

The power commander should work with the deluxe. The connectors should all be the same.

If you installed a slip on (without the power commander) and left the o2 sensor connected the ecu should be able to compensate for the change. If you added a mod to your air intake on top of that probably not. However, the bike runs lean from the factory so you will get a much improved throttle response making it more even especially at lower rpm's with the power commander. It sounds like the o2 eliminator may have been plugged into the wrong connector. Both the o2 sensor wire and the speedo wire go down the frame towards the rear wheel but they diverge and the o2 wire goes along the under side of the engine. You should be able to tug on it and see which connector it's going to.

But you will need to get it on a dyno and you will love the results.

What Chync said about the cables is what I was trying to say but did it badly. Thanks Chync for making it clear.
