New H.D. tuner, Anyone see this yet???????????


Screamin' EagleŽ Street Performance Tuner Kit

The Screamin' EagleŽ Street Performance Tuner is designed to simplify management of street-legal performance calibrations as EPA-compliant performance modifications are made. Once installed, the kit will allow the dealer to upload the latest ECM calibrations for your bike's legal state-of-tune for only a minor labor fee. Start with a high-flow air cleaner and Street Performance mufflers, and the dealer can upload the calibration that provides the best performance mix. Add a Big Bore Stage I or Stage II kit later, and the dealer simply downloads the proper ECM calibration to match the model and hardware. Plus, the dealer will have on-line access to the latest factory calibrations, so they can load the most up-to-date parameters whenever you have your bike serviced. Available September 2010.

Fits '07-later EFI XL, XR, DynaŽ, SoftailŽ and Touring models (except Trike).

No I haven't seen it. Looks like a waste of $$ though. It costs more than a power commander, only works for "street legal" mods, has to be uploaded by the dealer for a cost each time..... and uses canned maps so it presumably doesn't allow for custom maps/dyno tuning....... basically a hybrid of the PC and a much crappier version of the SERT

 

I agree who wants to go to the dealer and pay them every time you change something.

 

Thats what you have to do when you have a SERT?

 

Old SERT perhaps but the SESPT use to have Smart tune in lieu of a download. I thought the dealer always had the capability to download stock MAPs corresponding to HD hardware mods. Is HD now charging and extra $329 on top of the labor charge? Or have they reduced the price of SESPT?

Minor labor fee may still be $125?

 

You don't have to go to a dealer to tune a SERT.... I had mine installed by a tech that has his own shop. Did a excellant job compared to what a dealer did originally with a canned map.

 

What exactly is the difference between something like a PCV and a SERT? Does the SERT auto tune? Newb question, but I have always been curious. OR is a SERT just HD version of PC?

 

The PC is a piggyback unit that u install and it stays on the bike. It basically takes the signals (air/fuel, ignition, timing etc) from the stock ECU and changes them. The SERT is basically a "key" that allows you to directly reprogramme your ECU. Both have their pros and cons. The PC is nice cause you can just unplug it and go immediately back to your stock settings and/or put it on a different bike.... the SERT changes your ECU program (which can be an issue for warranties etc) and is married to your bike and yours alone. It cant be installed on a different bike.

 

The phrase "The Screamin' EagleŽ Street Performance Tuner is designed to simplify management of street-legal performance calibrations as EPA-compliant performance modifications are made." screams NOOOOO WAY JOSE!

 

The PCV is a add on module that modifies ECU outputs based on sensor inputs to enrichen the mix, make more power. You have to disable the O2 sensors for it to work, and also find a place for the module (can be a PITA on a dyna). Its a cheap and dirty way to make good power while still giving you decent drivability. You can use canned maps or have relatively inexpensive dyno tune. You have to be careful about sealing them from water.

The SESPT/SERT/TTS kit are software packages and an interface box you temporarily connect to the bike that programs the ECU MAP to do what you want, typically more power, better drivability, good mpg. The ECU retains its full function to adjust/tune to fuel from tank to tank and some minor modifications (the O2 and ping sensors remain functional). TTS and SEST includes a self tune function where you can calibrate the bikes ECU to the VEs of the engine yourself, making for an excellent street tune. You can either use canned maps, your sweat equity to tune these yourself, or hire a dyno operator. On the late model bikes, this is a better system than a PCV but costs maybe $100 more cash. Consider the TTS kit if you go this way, its a better tool.

The full autotune systems (TMax, PCV +autotune) cost more money and are a more significant modification. They replace the stock O2 sensors with one with a wider AFR range and are self adaptable, although you can adjust them if needed. There is a difference of opinion just how effective they are in the end, but once they are installed they pretty much tune themselves under all driving parameters where the TTS/SESPT programed ECUs auto tune just when in the closed loop range (i.e. not WOT). The autotuners can handle a much broader spectrum of modifications than the ECU programers without manual adjustments (retune).

There is much discussion over in the EFI forums on the benefits of each. Enough to make your head spin.

PS there are also fuel packs which is an add on module that adds fuel to the open loop areas, the ECU closed loop functions remain intact.
