Hello,
I have a 2007 Heritage Softail. This fall/winter I am going to upgrade to Vance's & Hines Long Shots & stage 1. The only problem I have is this. My dealer is telling me I don't need a Power Commander for fuel management. They aresaying the O2 senors with the on-board computer will do all adjusting. I have contacted several other Harley dealers in the area. Allare telling me they use some type of fuel management. Just wondering what my best optionswould be.

Is your dealerjust tellingyou that you don't need a Power Commander or a Fuel Management System period? If someone in charge of a service departmentis telling you that you don't need a Fuel Management Sytem for a EFI bike with Aftermarket Full Pipes & Air Kit, I would not let them near my bike.

The so called "On Board Computer" or ECM I believe it's called, can not adjust to the new set upby itself, it has to be adjusted by some means with a Fuel Management System. Different brands and makes do this in different ways. You could do a search on the subject of Fuel Management Systems and find out more about which ones do what and how.

Later,

Nope, the 02 sensors are not going to get you where you want to be. FuelPak, SERT, PC III...you will need something to take care of the lean fuel condition.

Hey guys thanks for the replies.

Here is another twist to my questions. My original plans were to install the 07 Vance & Hines Big Shot Long with (2) O2ports, Stage 1 upgrade (K&N or SE) & also a Power Commander. I now see they offer a Power Commander with O2 eliminators. Will this mean I could use a 06 V & H pipe with no O2 ports using the eliminators?

 

Hi just got done taking out the new Power Com out
I had my ride back they installed a new pcm when I got it back it ran ok still back fired a bit so after a while a installed the power com it seem to be better then slowly over the next few weeks got worse A friend had a race tuner installed and tuned by a local dearler so I took a shoot and did the same thing If you ask me thats the way to go now the power com sits on the shelf want to buy it LOL

Many similar issues as you. The short answer here is I don't think it is a good idea to eliminate O2 sensors.
