Yesterday I installed a Stage 1 Screaming air cleaner & 1.75 Fullsac baffles, now I'm the one who is baffled.Everywhere I read that an ECM calibration must be done. I rode about 40 miles after the install. There is a definite improvement in acceleration. The bike runs fine at all rpm's no backfire,popping or other noises. Is it really necessary to have it remapped? What are the con's of notrecalibrating? I would much rather ask a stupid question than make a stupid mistake. Thanks kb

These bikes run really lean in The stock configuration. By adding a free flowing intake and exhaust the engine will breath more efficiently and therefore be even leaner. You will damage the engine over time with this excessively lean condition. Get the TTS Mastertune and load a map from fullsac for your setup and you'll be suprised how much better the bike will run.

Pull up NIGHTRIDER.COM and read through all tabs and you will have your answer.

As your bike sits now, the EFI will keep the air/fuel ratio at or around the factory setting of 14.7:1 in the closed loop mode only.  This is still really lean for the engine and was only ever to keep EPA happy.  In the OPEN LOOP MODE(which your bike goes into upon special factors and conditions, like rapid acceleration, etc.) the AFR will be much, much too lean, leading to the ultimate destruction of your engine.

If you purchase a re-cal from your dealer(stage I download), they can only return the AFR back to EPA standards, even in open loop mode.  Pro Super Tuner, TTS, Power commander V, etc. including canned mapping thats nearly perfect or mapping done by a tuner that knows what he is doing are some of the options that can put your fueling where the engine will run right and run cooler, whether installed by a dealer or you.

The performance by way of torque and HP that you should gain by getting the fueling right will probably be fairly substantial.

Good Luck and Laters.....

Thanks for the info.Now the stealer gets more of my hard earned CA$H.

if you check I believe you will find that there is not a stage 1 download for your bike.  the cvo se bikes are already at this stage.  you need to add some sort of a tuner to change your parameters.  there are alot of opinions as to what is better so read them all and make your best decision.  good luck

I know this thread is about a week old but......



Another thing to consider is, and has been said, the stock calibration is lean but... your ECM adaptive learning has not yet learned your new free breathing adjustments. So you may be, right now, running a tick more rich than you will be in about three tanks of gas from now. It takes a few tanks for your ECM to adjust back to the factory calibration in closed loop.

Now with that being said. From what I do understand at this time... a dealership cannot flash, using their digital technician, a stage II canned calibration anymore. The new style SEStreet has pretty much taken over dealerships which will only allow canned street legal calibrations to be flashed. With a SEStreet tuner the owner cannot flash their bike themselves. The dealer must do it for them and have in their possession a USB key token and your purchased SEStreet tuner first. With the SEStreet tuner there is no adjustments allowed in the calibrations by an outside party (the owner or anyone else).

Although I have heard second hand that there are still dealers out there selling their stock of SEPro tuners... these tuners will be in short supply and soon be gone. Welcome to the new age of EPA complaint tuning.

Depending on what you have in mind for future mods or you simply want more out of what you have now... do what was suggested above.. TTS and Fullsac calibration. Guaranteed you will be very happy with the results and it will be the best money you've spent on your ride.

Thanks for the info. You are correct about a stage 1 . I rode to my local dealer yesterday to have it done and they also said no can do. Now I guess I need to buy a tuner etc.etc. It just never ends,does it?

you'r not serious, are you? SEPST discontinued?

[RedDevil]

No, the SEPST is NOT being discontinued.  It's still being offered in the SE Performance Parts Catalog (for "off-road and race use only") and still has the same functionality.  The tuner that is being discussed above is a new Street Legal interface that is sold in the regular P&A catalog.   There's about $100 (the street legal one being cheaper) and a whole lot of functionality difference between the two.

[grc]

I haven't seen any information about the demise of the "Racing Use Only" SEPST, but it wouldn't hurt my feelings at all if H-D were forced by the EPA to cease selling it.  It's a total joke that they are allowed to put out lousy running stock bikes and then sell a device to defeat the emission system so the bike will run better.  They are the only vehicle manufacturer I'm aware of that gets away with this crap.

Do yourself a favor and spend your money with the aftermarket rather than reward H-D.  And don't bother wasting your money on the Street Legal version either, it doesn't let you do anything other than download street legal maps at your friendly Harley dealer (for an additional charge).  Those downloads won't improve the way the bike runs in closed loop mode.

The names are so confusing now....  so I'm using SEPro for the SE Pro Tuner and SEStreet for the SE Street Performance Tuner.

The SEStreet the new and cheaper one that will only flash street legal calibrations and only by the dealer. The SEPro is the old 2008 design and higher dollar tuner that you can use at home to Smart tune your bike or take to a Dyno.

I've seen the SEPro catalog page marked out with a big X over the 32109-08 at different dealers parts counter and a big warning written as "DO NOT SELL" but I have heard third hand that some dealerships are trying to get rid of their old stock as quickly as possible.

That's entirely up to the dealers if they want to stop selling it.  Probably very likely the owner is getting a little nervous of the EPA coming around to visit his dealership, which if they can prove they are tampering with the exhaust systems, can levy a substantial fine on them.   

If one dealer won't sell it, go to another, they'll take your green backs I'm sure.

[kraut]

Hmmm,

does anyone know/tried if there really is any difference in the hardware between "SESPT" P/A 410 00008 and SEPST P/A 32109-08B?

I'd rather doubt ...
