Total Screw Up By Powercommander

Posted this to Mr. Dynojet in another thread but wanted to give a heads up in case someone else is not aware.

Mr. Dynojet

As per your suggestion was going to get out the laptop and check everything. SO, I took out install instructions to make sure I had not screwed anything up, according to directions I had not.

BUT, just to be sure, I went to powercommander website and looked up installation instructions for my unit.

LO and BEHOLD, powercommander had changed the installation instructions to include putting on O2 eliminators. A step they totally forgot to put on the instructions shipped with my unit. THIS is total BS.

If it was not for this site and the endless reading I have been doing trying to educate myself, who knows how long I would have left things this way.

BIG QUESTION, I have run my bike with the O2 elimators for @ 5500 miles. WHAT kind of damage do you thing I may have done?

I think you meant "without" the O² Eliminators or ? Regardless you can run either scenario installed or not. Depending on your desire to be in the "closed loop mode". IMO there's no adverse issues to your ride if all other settings (maps) were correct for your build.

Granted its bitch not to have the latest instructions, always check the web. Especially if I have extra parts.

O2 eliminators only help the ECM think there are still O2 sensors attached and this prevents the ECM from giving an irritating engine code. You can run with or without O2 eliminators but the O2 sensors should not be hooked up.

I doubt any damage was done as the stock configuration is about as lean as it gets and the engine can handle that.

yep, the eliminators just keep from throwing a code.

usbpk9, take a deep breath and relax. No damage is going to be caused by leaving the O2 sensors connected. It only means that the bike will run the same AFR in cruise that it did stock. We even offer a PCIIIEX for the California market that leaves the O2 sensors in place. Several other "tuning modules" have the O2 sensors left in place, so there is nothing to worry about.

Here is what you need to do. First, take the map that you have loaded (M818-028) and zero out all of the fuel changes from 40% and lower (both front and rear tables). Now, with the O2 sensors still connected, go out and ride the bike for a day or two. This will reset the O2 offsets back to where they need to be. After that reload the original map and disconnect the O2 sensors and install the bypasses.

I apologize for the problem with the guide. I am not sure how old of a guide you have.

Once you have done the above let me know if you are still having running issues and I can try to help you further.
