Power Commander Questions
I am contemplating buying a PC III for my 06 Fatboy. I have Porker Hatchet pipes and the SE A/C kit. I also had the download put on my bike. However I am still getting backfires from time to time and the bike seems to be running a bit lean. I just want to know if the PC III will fix the backfires or not. I already spent $200.00 on the ECM download and received so so results. I don't want to drop the additional cash on the PC III if it won't make much difference. Any help will be appreciated.
Also, where is the best place to purchase a PC III?
Does the PC III module actuall mount on the bike? If so where?

RE: Power Commander Questions
Have one on my 05 Fatboy. It's mounted under the seat by the battery. Had it dynoed when it was installed and have had no issues at all.
Best price I could find was through Eastern Performance on Ebay.
Hope this helps.

RE: Power Commander Questions
Man I am so confused. I don't want to spend the money on the PCIII if the SERT is better. I have already spent the money on the download which is rendering undesirable results.
Several dealers have told me that the pops on the decel and an occasional backfire is "normal". I am not worried about the pops for performance reasons, I am just worried about doing damage to the engine.
Also, If I buy a sert or PCIII, I will need to have the bike the dynoed to have it tuned correctly? What will that cost me? I am not opposed to spending the money, I just want to get it right this time.

RE: Power Commander Questions
What do I do if I cannot find a map on the Power Commander site that matches my set up? I cannot find one for my pipes (Porker Performance Hatchets).

RE: Power Commander Questions
Hey Warg,
Check here for good price on the PCIII http://www.fuelmotousa.com/. As for the download, it's a canned map the dealer downloads onto the ECM. It may or may not be close to your set up. Have you checked for leaks after the exhaust was installed? That could cause some popping. As for the SERT/PCIII, both are good fuel management devices that have the most flexibility for future mods, i.e. big bore, cams, etc. If you don't plan on any of that, a TFI/DFO my be what you need. Check here http://www.dobeckperformance.com/. Hope this helps. Good luck and Ride Safe.

RE: Power Commander Questions
I plan on installing a big bore kit next year. So I think the PCIII will be the way I go. It seems to be flexible with mods and more cost effective than the SERT.
Getting the bike Dynoed is not required on the PCIII right? I know dyno tuning will get me the best possible performance, but as long as the map I install is tailored to my system or is at least close, then the popping and backfiring should cease right? I will get the bike dynoed eventually, I just don't have the cash to do it and buy the PCIII right now.

RE: Power Commander Questions
Well, on an '06 it mounts underneath the ECM between the mud guard and oil tank where softails are concerned. It won't fit under the seat any longer because the rear fender doesn't have a depression in it.
If you're going to add serious performance enhancements then you need to be able to dyno your bike. The only way to do that is with an aftermarket ECM/ECM add on. SERTs, SERFs. PCIII's, V&H etc. are add ons. They replace the fuel curve data with one that can be tuned in various ways. Some also allow you to modify the timing blocks. (Blocks being cells of data that the ECM refers to when certain conditions apply). In either event, if you don't like the lean EPA condition that your bike is operating under, then you need to ask your Harley dealer to take back the download and credit it toward a SERT. (You can use a download and a SERF if you have no other plans for your performance enhancements). If your dealer is also a PCIII dealer, then you might try the same tactic for that choice, which is cheaper than the SERT.
