Scremin Eagle Pro Tuner

[hd1084]

After some research and gathering opinions from others I pretty much have decided to go with SE255 cams and a SE Pro Tuner for my 2010,  96" Street Glide.
I just wany to keep things HD per say. Anyone else running with this set up??  Thoughts and or opinions??

[1931jamesw]

Why not Andrews 48H and TTS? The 48's make better numbers and are the "non-EPA" version of the SE255's and the TTS has more capabilities than the HD tuner. JMO, run whatever tickles your fancy.

Curious why you think you want to keep it pure HD?

I want to keep everything HD per say.  Not to say the after market stuff is not better. I just want to be able to go into a dealer along the way on a trip if I have a problem and know I have a better chance for repairs if the need would arise. JMHO.

I have a map if you need it.......

I agree there are a lot of options but we have had great results with the SE255 & SE204 cams with the 96" and Pro-Tuner.

DOPE!  Didn't see the "96"  I'll move on... LOL

[DrSpencer]

Does the SE Pro tuner allow DIY tuning with a laptop, like the TTS?
Thanks

[glens]

The "Pro" model, yes.  It has the capability of logging data without a pee-cee connected, but after that it has a bit less capability than the TTS.

Maybe I wasn't making my question clear.

Can you tune your bike yourself (while riding around with a laptop) using any of the HD tuners (SERT, SEPST, ect.) like you can using a TTS tuner?
Thanks

[Grillfish]

glens got you covered.  No laptop needed with Pro.  Just record using VCI, download the data to your PC, run Smarttune, reflash, etc....  Manual is pretty straight forward.

[Dennis The Menace]

DrSpencer, you dont need a PC connected to the bike when out doing Smart Tune (ST) runs.  Connect the VCI to the bike via 4 or 6-pin cable (depending on model year-2012 and up use a 6-pin plug), connect the PC and download the map to the bike.  Put it in data collection mode and go ride.  The VCI has an on/off button, so you can start and stop the recording as you wish.

When you get done with the ride, DO NOT SHUTDOWN THE BIKE!  Stop the VCI recording, then shutdown the bike.  Hook up the PC, download the recorded data, and you then adjust the original map with the downloaded data.  You can then just save it is a new map, or fine tune it by hand and save.

Connect the PC to the bike again, and load the modified map to the ECM.  You can at this point do another ST run, and keep tuning missed areas, or just call it good, depending on how many cells you hit on the last ST run.  IME, it takes about 3-4 runs on the bike to ensure you hit the cells that are feasible to hit.  Going over 80% throttle will not get you anything, and trying to get 1000 RPM at 45% throttle aint gonna happen either.  Some cells you cannot hit via ST run.

You blend the cells you cannot hit on a ST run.  So, its a manual effort for some of the cells, but the ST hit cells are where you ride, and they will be very close.  Keep in mind, you can do a ST run this morning, go out in an hour and some of the prevously hit cells will change.  This is normal, as you would find it near impossible to exactly duplicate the outside air temp, humidity, barometric pressure, internal engine temp, etc for each run for each cell.  So, dont worry about cells changing slightly with each run.

I have used the SEPST on 2 bikes, had a Race Tuner on another, and have also used TMax and RevPerf EMS.  The RevPerf is easiest, plug and play...no tuning required, and the bike ran great.  But they dont support the 2010 and up exhausts, and I didnt want to modify mine, so went to SESPT on my 10 RG.

The thing that many lose sight of regarding a map: its a baseline for the ECM to load/use when the motor is running, and will make constant adjustments hundreds of times a second based on the various sensors on the bike.  The value of each map cell is merely a starting or reference point for getting close to an optimal point.  It may, or may not be the optimal value, as that depends on numerous factors; air and motor temps, throttle position, stoich of the fuel, RPM, barometric pressure and on and on.  If the ECM only used one value and didnt adjust it based on sensor inputs, the motor might run fine at sea level, but run like crap at 12,000 ft, much like you might experience on a carbed bike to some degree.

Sorry, I have over simplified a complex topic, and may have butchered it.  But, my point is that you dont have spend hours and hours trying to hit every cell and find the prefect running bike.  Its actually easier than you think, and some things are simply out of your control, so do some runs and ride the bike--you will be happy.  I have only done 2 ST runs on my current bike, and it purrs perfectly.  Even on 87 octane fuel as 6,000 feet where I live.

Very well said Dennis. 

[DrSpencer]

This process sounds very similar to what I do with my TTS tuner, only I ride around with my laptop in a backpack while tuning.
I'm almost afraid to ask, but if the SEPST doesn't require a laptop while riding, and there is no issue of compatibility with the HD dealers Digital Tech, then what is the advantage, if any, of using a TTS tuner?
Thanks

The patriots almost beat the Giants in the Superbowl it was pretty close....who would you have wanted to bet on if you were betting?  From what I have gathered (no personal experience with the sepst) that is basically the difference

[glens]

From what I've gathered, if you learn the foibles of both systems you can end up pretty close to the same results with either of them.  Carrying a laptop with the TTS certainly has the possibility of being an inconvenience as compared to the self-contained logging of the SEPST.  But on the other hand, you're extremely limited with the SEPST in terms of how much data you can gather in one session, so more sessions may be required.  In any event, I've got a Tour Pak so for my own bike/use this is a complete non-issue.

What I know I like about the TTS is that I can get the VE tables much smoother than I could with the SEPST.  I know, you can manually massage the VE tables directly with either, but if you want to stay closed-loop you'll not have gained anything for your effort and may even cause detriment.  The extra factor of "EGR" in the TTS really is valuable and anyone who's actually put it to use knows what I'm talking about.

While the average user can only really benefit directly from half of the cam selection stuff in the TTS, anything at all in this regard is better than the nothing you get in the SEPST, especially if you're using non-H-D cams.

I know from experience with the TTS that when I'm performing v-tune operations, things go exactly as expected for me.  I understand that with the SEPST, its equivalent setup makes changes to the calibration for that purpose and does not inform you of them, that you can only discover them by doing a little detective work, so to speak.

I've got mixed emotions about having no choice or control over having my ECM flagged "read only" by the current TTS software.  I can see both sides of the argument quite clearly and agree with aspects of both.

I like how the TTS has the capability to save/restore the ECM, which the SEPST will/can not do.

To my perspective, the TTS gets the nod over the SEPST.  It may become more than just a nod in the future if we ever find out what TTS has done with the newer design.

[FLTRI]

For a stage 1 bike a Power Commander can be used to improve driveability and overall power.
Any more than that, IMO, a reflash system to the OEM ECM is best.

That said, IMO if you have or intend to build a bit more power into your engine the additional features with the TTS system (ie: cam estimator, complete t/p control, monitored v-tuning, a real biggie...temperature adjusted timing control, closed throttle spark control (used to help decel backfiring), adjustable adaptive knock retard, AND a feature very few have realized the benefit of...EGR adjustment. And a few tables in the background SC found to improve tuning.

Other than the above differences the SESPT is sorta the same?

[DrSpencer]

Does the SE tuner have the ability to recalibrate the speedo? That's the reason I bought the TTS.

I have no complaints with my TTS. My only concern is what do I need to carry with me to get service at a HD dealer when I'm out of State and break down?

[mgmmgm]

I went with the SE super tuner pro on my 2011. I just wanted my dealer to be able to tune it, which they did a great job with that, and it runs very well.

Cheers,

I admit I only owned a RaceTuner back in the pre-SEPST days, and much has changed with the unit (and software) since then (the Race Tuner became the TTS, as the RT was made by Mastertune for HD back in the day).

But, from info posted by the experts here on HTT, like Steve Cole and Bob (FLTRI) and others, the TTS is the Cadillac of tuners.  The SEPST is the GMC of tuners.  A few less capabilities, but still a very capable tuning device.  TTS gives the pro tuner more control over the finer points of the tune, that the SEPST does not.  For a pro tune, TTS.  For a DIY tuner, they are both good, with the SEPST more convenient since a computer doesnt need to be lugged on the bike.

Money well spent on either product, IMO.

Can the SEPST recalibrate a speedo?

[1931jamesw]

Im pretty sure the HD tuner cant calibrate the speedo. I think there are also several other features the TTS has that the HD tuner doesn't. Maybe Steve Cole will chime in.

Not that I see in the software, nor the user manual for Super Tuner, no.  So, my uneducated response would be no, you cannot recal a speedo with the SEPST.

You are correct! No speedo calibration available w/SESPT. I didn't include that feature in my previous post as it really doesn't affect tune quality...just a very handy (save on add-on recalibratoras)tool when ratios (tire size, primary/secondary ratio changes.
