Terry, I just came from my dealer, (MC, not dope) and he says that the Race tuner can be installed initially in two hours, and then re set every time I do a change in 1/2 hour. Is this true in your experiance.
You know I don't trust them, since they are the same idiots that insisted i needed a HD download.

The initial install should take 1-2 hours. The actual tuning depends on how good your mechanic is. To really tweak it right you need a dyno. It also depends on what kinda upgrades you have. My Rineharts take longer because of the way they are designed. Once they are tuned correctly they run great. I would not want a new mechanic trying to do it though. A simple air cleaner upgrade with some SE Slipons should not take as long. The race tuner has maps installed on a CD Rom and on the Harley website that can be matched to your upgrades. Once that is downloaded it can be tweaked to adjust any little problems you are having. The simpler your upgrades, the simpler the tune.
Still dazed and confused here. All these upgrades for SERTs and downloads? For what end result?? More power?, Speed? Increased MPG? So I can grunt louder than the other guy? Just a need to spend more $$$$$$$???? Honestly I really don't get it.

Increased speed, better mileage and more power are just by-products of a well tuned engine. It's really more for the health of your engine. If you modify the intake or the exhaust, you are changing the amount of air that the engine pumps. In order to have a good running engine, you have to compensate for this by altering the fuel/air mixture and possibly the timing. Sometimes you need to adjust the idle speed or the way the cold engine enrichment is set. On a computer controlled EFI engine, the only way to do this is to alter the electronic signals that are sent to the engine from the ECM. If you don't have a properly tuned bike, you may experience overheating, poor fuel mileage, or at best, a engine that just doesn't perform well. The SERT is a tool that allows you to change settings inside the ECM. The PCIII is a bolt-on device that intercepts the stock ECM signals and alters them before passing them along to the engine.
It's all about tuning. Just like the mechanic used to have to put new points, plugs, adjust timing and adjust the carb in your old car... Now it's all computer controlled and EFI systems are no different, they just require different tools - tools like the SERT.

I bet you can count the members on this forum who are running stone stock bikes on one hand and have a couple fingers left over. Everybody changes their pipes and air cleaner. That's just the way us harley guys are. The SERT is the best tuning method to make the bike run the way it should. We aren't talking about ported heads and high compression pistons here. Just the standard minor mods. I started this thread because I probably get 2-3 PMs a day or I read another 2 or 3 threads asking for this info. The end result is a harley you can have some real fun on. That's what it is all about.
the 05 harleys and earlier have an open loop fuel management system while the new 06's have a closed loop design, this is a huge differeance. and it is also the reason why the 06 bikes are having so much trouble with the download. get a power commander or a sert. do not waste your money on a hd download.

It's only the 06 dynas that have the closed loop fuel injection .

This is true. Everybody freaked when they thought all the 06's had this. Hell, they didn't even give the dealers the info they needed to fix all the EFI problems on the 06's. Even still, for some reason the download quit working properly (or marginal at best) in 05.

I don't undertand why people freaked about the closed loop EFI anyway. 02 sensors just help the ECM make corrections to keep the bike in tune. Even if they are narrow band and the corrections are small, I see this as a good thing. You get the right map in the ECM and the sensors just help it run better. Am I missing something?
