According to Dynojet, without installing the O2 eliminators, "the PC will not be able to make the proper fuel changes anywhere below 50% throttle". I am experiencing surging below 50% throttle which is expected without installing the eliminators.

I then tried to figure out how they could have adjusted the A/F below 50% on the dyno runs. I called Eastern Performance and found out that they DID NOT monitor A/F and make adjustments accordingly (I suspected that). Basically The dyno run was useless. Matt (the tech at Eastern) was not aware that you needed to replace the O2 sensors with sniffers to get the a/f on this setup.

Eastern does not have the correct equipment to do the job so they asked me to return the bike and they will remove the power commander and reinstall the original air cleaner. I went to them because there are an approved center, but now I can see that that does not mean anything.

Can someone recommend a good PC tuning shop here in Maryland?

 

Time for a SERT.

 

The more I read the more I'm leaning toward the
SERT. I just wish the price would come down, like
a bunch. LOL

I'll be trying Frederick H-D for my PCIII map soon. That would be a ride for you but I've had good experience with them in other service. Good luck!

Thanks, I will call them to see if they can tune the bike with a Arlen Ness AC and stock pipes. I called several places, but no one has the setup to tune this configuration. There is an '07 stock map so I will start there.

 

Try calling Jamie at fuelmotousa.com, he knows what's up with PCIII's. He might even send you a map for your setup.

 

I ordered a PC from Jamie on Monday. Shoud be here by Thursday. Dynojet posted the stock map for the '07 last Friday. At least this is a start.

 

FYI.....The Power Commander will alter the programmed map of the computer in specific increments. It does not adjust on the fly and neither does the SERT. The biggest difference between the SERT and the Power Commander is the fact that the Sert makes changes to the computers programming while the PC alters it between the computer and the engine (and the price). One other thing, it seems that maybe a Terry Industries tuning device might be the way to go with these new o2 sensor equipped bikes since they have a device that is designed with o2 sensors in mind. Just a thought. I'll be looking into it pretty soon since I'll be buying my new Nightrain here pretty soon. Good Luck

I emailed Terry Components about their product on the 07 (Nightrain in my case). I will let you know what they have to say.
