Just posted in Tech section and thought I would share with the group I spend most of my time with in Touring.

I am sooooo embarrassed.

I wouldn't be too hard on yourself, you didn't hurt anything but your bank balance.
I would buy your Auto tune but my 2011 uses the new size sensors,I just ordered a PCV or I would buy that too.

Yeah ..... don't feel bad about that at all.

The advertisements and even web sites for the aftermarket tuners, and the accessories you can get for them, can be really confusing (to say the least).

It's too easy to end up with redundant or incompatible equipment, especially when there are web sites for shops saying things that 'won't' play together, 'will' play together (like a site the says DJs LCD-200 will work with any Power Commander with USB).

It's one reason I posted my thread on 'clearing up the PC confusion', to help others avoid this type of confusion and expense.
And it certainly can be an expensive learning curve.

I was lucky to catch that a WBC2 can't work with a PCIII before the UPS guy made the delivery.
I contacted the shop I bought it through and they told me to just refuse delivery, which I did.

So ... don't feel alone in this at all.
Sometimes I get suspicious that the mfg's are just a bit more than nebulous in their descriptions ....... on purpose.
 
I saw your thread.........of course you and iclick are light years ahead of me in understanding the details of using these.

I need to find resident expert on here for the SEPST to counter what (little) I know about PCV's. Jamie at FM, iclick and now you have some great threads out there regarding the PCV. Have not found that vast and deep knowledge on the SE...........yet.
 
You're a dummy! (Of course I'm just kidding)

I agree the only thing hurt is your wallet and pride. I too am in the same boat trying to figure out which tuner to go with. Wading through all the pissing contests between PCV, TTS and Thundermax (or whatever its called) is a real chore.
 
That's OK, I feel the same way! Since we have 07 and 08 Road Kings one with two tuners and one with none.

Pretty sure I am going to split them up but which bike gets which is anyones guess at this point. I am finding in my research that the SEPST (maybe the TTS?) is geared for the dyno and/or professional tuner whereas I know first hand a good map on the PCV makes a great "plug n play."
 
I feel that most of us are all pretty much in a learning curve with this stuff, as 'certainly' are many of the retailers (evidenced by their missunderstandings of what does what).
I just recently went through the process of buying my tuner and accessories, so my "stumblings" are a fresh wound.

I now sorta agree with iclick that it is probably best to buy from a dealer like Fuel Moto, who has intimate knowledge of the products and can both keep you from getting things that are redundant .......'and' provides more maps for different configurations than anyone else, along with all I read about the outstanding help Jamie provides to their customers.
I'm just not 'yet' convinced that a map for a bike that is developed on a dyno for a different bike, at a different time, and in a different environment, is 'in practice' any better than doing AFR tuning.
But I will concede that may very well be wrong ........ and time will tell as more people start to use the AT feature for the PCV, and others (like me) use the WBC to modify maps based on AFRs for bikes that can't run the PCV.
In a perfect world, the best situation would be to go out and buy our own dynos (you know ..... if we all had Bill Gates' bucks) and use that to develop our own maps.
But after seeing the results of the auto-tune in the recent Fuel Moto - Woods Cams thread ..... I'm pretty convinced that if you have a bike that can use a PCV and AT, and with the extended warranty and support that Fuel Moto provides ...... you are spending the smart money to buy that equipment, and even smarter if buying it from Fuel Moto.
 
since you have the Sepst i would use it and get a tune. If you have the software it will do an update and download all current maps usable for that tuner. All kinds of tunes for all kinds of setups. Or you can have it tuned with the tuner. I have the sepst and download my own maps. It is only good for one bike, once you use it on your bike it can only be used on your bike. The PCV can be moved from bike to bike. Also the sepst does not stay on it is just an interface used to load the map into the ecm.
 
Since I have pretty basic upgrades; true duals, SE A/C, V&H slip-ons and will do this after I throw in the SE255 cams there is probably a map in the list similar already. Heck, could download and look now to scope it out. Then take it once loaded on ECM to the tuner for "tweak?"

Does the SEPST use the exhaust sensors (like the PCV/AT combo) to feed information back to the ECM so it stays within the parameters of the map loaded or are the sensors dead weight and not in use?

I like my PCV map but liked the technology of the exhaust sensors feeding usable information back to keep the ECM in the right zone. If in fact....that's what they do after loading SEPST.
