Default 883 - 1200 conversion

Hi guys,

My local dealer has a deal on an 883 -1200 conversion (SE kit) but they are insisting that they use the Screamin Eagle tuner on it. Which is fine but at the moment I have a 3rd party tuner fitted and it works fine.

So my question is, if they use the SE tuner they will flash the ECU with new settings for my stage one and 1200 conversion, if my bike runs like cr*p because of it, will I be able to just add my 3rd party tuner and adjust as necessary? I don't have a PC and don't want to take it back to the dealer if it runs poorly, would rather sort it myself. At the moment I have the standard SE filter and was thinking about changing to a K&N which I think might have an effect on the running of the bike, hence the tunning might need fiddling with. My tuner is a permanent fitting and really easy to use but it would also be nice not have the extra cables hanging on the bike.

FYI I have an '09 sportster Iron with V&H slip ons and a SE stage one air filter (29782-07).

Thanks guys, can't wait to have that extra power! What is the BHP figure for a 1200 conversion?

I believe in Race Tuners and Dyno tunes, I don't understand why anyone would do something 1/2 way on the newer fuel injected bikes.
The RT isn't a bandage like a lot of the aftermarket tuners, you can make the bike do what ever it takes to run at it's best.
If you are short on scratch then wait until you have enough saved up, you will feel the difference.

It really isn't about the money, more about what I can do at home without taking it to the dealer every time I need to adjust something. I know my dealer isn't going to run the bike enough to know how it runs after the conversion so was more inquiring abuot how easy it is to adjust things myself.

But I really am looking forward to having it done!!!!!!

Thanks for your help Jag.

For my conversion, I was offered either a download or to buy the race tuner. I chose the download simply for economic reasons, but will need to do something if i want to upgrade my exhaust in the future.

I understand why the dealer requires the change being done by them, mostly likely for workmanship and warranty issues. With nothing being done, the bike will run like ****.

That was exactly the reason (warranty) they gave me but my present fueler/tuner will do 1200 bikes too, just need to change the settings.

I'm more concerend about how easy it is to change the settings etc with the HD tuner if I change my pipes and exhaust...I already have a stage one fitted but if I was to add a more free flowing filter etc the bike might not run so well...

You may wish to consider a Power Commander V. Quite a bit cheaper way to go and there are many maps available from FuelMoto USA.

The SEPST is the way to go. It has way more user adjustability than the other "piggy back" units. All you need is a PC/laptop, the software, and the cable kit along with the tuner(VCI). Yes it's expensive, but you can tune it yourself with the smart tune function. It doesn't stay on the bike, unless you are making recordings for the smart tune, or informational purposes. After that, you unplug it. It makes the changes in the ECM, not trying to fool it. I love mine. Yeah, the VCI locks itself to the bike, big deal. It also saves the current tune you have loaded in the bike. Have problems on the road, have to reload your tune, whip out the little box at a dealer and they can load it up. If you want it dyno tuned, go ahead, make sure they use your VCI, and you've got the tune. Only drawback is you lose the stock tune, never to retrieve it. After that, any tune on the VCI can be recovered from it. I still haven't received the tune from the "other buys" that I bought the PCV from (when I used it) and requested a tune for my particular combo I was running at the time. I have the Fuelpak, PCV and the SEPST. Hands down, the SEPST gets my vote. The others were alternatives to the real deal. It's your choice. All of them have the "Off Road" only designation, and are subject to void warranties, even HD's own product, although I think I saw a street legal fuelpak or PC being offered at one time. Considering you want to convert it, it's the logical choice. The 1200 tune comes with it. I still haven't gotten the info on whether or not the tune affects the speedo or not. That would be the only downside, IF it changed the speedo cal from 883 to 1200 because the gearing is different. No where in the software does it let you designate gearing. None of the others did either...

I'm not changing the gearing, the SE kit only changes the size of the engine, it doesnt include anything to do that.

I think he's saying that the 1200 download will make an 883 speedometer read like it has 1200 gearing/calibration, so the speedo will be out of whack. That can be fixed with another electric doo-dad from Dakota Digital. So I've heard.

Ahhh right got ya, yeah that will be a problem if it does that, I'll ask my dealer about it. I'm kinda hoping that there will be an 883 - 1200 conversion setting on the SE race tuner so I wont have to worry about it.
