I had the PC V (and PC III before) with great success.  My issue with the SSERT and TTS is the requirement to have the AFR at 14.7 (ok maybe 14.4) and have the bike run hot.  In south Texas where the average low in the summer is 75 to 80 and the high in the mid to upper 90's with 75% humidity, the cooler the bike runs the better.

I know you can run them at 13.8 AFR but in open loop mode.  So why have the sensors???

that said the TTS appears to be a very good solution as you can set the AFR at 13.5 at idle which is you normally feel it the most.  ANd at the higher rate of you want.

Not sure where you got your misinformation but the purpose of the SSERT and TTS is to reprogram the ECM to the proper (13. A/F ratio and adjust the proper ignition timing.

A far superior methodology for accomplishing this than the PCV and III without interjecting another possible point of failure. Have used them all and am certified on the Power Commanders. The biggest drawback is the extra space they require that is in short supply on many models ( Softail Convertible and all softails particularly)

While they are sound products for the most part they do not perform any function not provided by the other tuners.

The autotune units do add functionality  desirable to a novice but you can use the thumb drive on the SSERT to perform the same adjustments to individual bike and riding style.

Also to just adjust the AFR to 13.8 in closed loop the XIED solution can provide this functionality for under $200 is easily installed by the novice technically tunes itself with the existing ECM and O2 sensors and can be easily removed for warranty.

All ways to solve the same problem but none the end all for everyone?

How do you use a thumb drive on the SESPT? Are you talking about the ability of the unit to record the 8 or 15 minute log that is built in or a thumb drive that attaches to it?

Yes the onboard ability to capture data and apply changes to the map. In its internal memory making it a portable recording device. By comparison the TTS which is very similar require you to take a laptop along in the bike to capture live data almost requiring a Dyno to perform live tuning.

And how do you make changes to the map without a laptop?

[Wheelsnkeels]

You don't, you do however collect the data without it. Prefer not to subject my laptop's to rides in the bags? Not the best environment for a laptop. This was enough advantage for me to choose it over the TTS

Worth mentioning also are the aftermarket ECM units like TwinTec w/ autotune easy for the novice and self tuning. Replacing the factory ECM means it takes no additional space and is plug compatible. Also easily reversed reinstalling the factory unit for warranty purposes if needed.

Also worthy noting is the SSERT and software can typically be purchased for the same cost as a PCV

So let me get this straight, there is a WB sensor that will work with the Delphi to properly adjust the AFR to what level you desire.  I was not aware of this. I was aware the TTS would work with the existing NB sensors and could overridden.

So where do you buy the WB sensors that work with the Delphi module?

Hogmike, repsonding to the post above.  Here it is:

What do you think?  Is the SSERT running in open loop or what am I missing?

I guess I'm missing something when some want to change their a/f ratios beyond what the VE's would dictate.
The TTS will keep closed loop operation at about 14.3 a/f. or so.
Of course, under loads and at the ends of rpm ranges, etc, etc. the ratio will change accordingly.
WOT  will require 13.0, 12.0 or whatever the dyno dictates.
In the real world, I ride at about 2400-3000 rpm under light loads to moderate loads. This is where I want my closed loop to operate for fuel mileage and good road manners.
When I peg the throttle, it responds as it should and the tune will go to that 12.0 or whatever, depending on load (MAP) and RPM.
I really don't want a device to richen up the tune at a "set 12.8", or something that overrides the O2 sensors across the board.
I know what I have works good for me, and other devices work good for others, but, this is JMHO
I'm not an expert with the TTS, but, I know enough to get my bikes to run well all around, and I like this product.
I did a lot of research before the purchase, and am pleased with my decision.
No disrespect to all you tuners out there, and whatever device you are comfortable with and get good results.

I'm not really sure this is the purpose of these devices, I think you can achieve those numbers with either of them, but, each bike is different and would benefit a good individual tune, preferably on a dyno.

I don't think your missing anything other than the ve's don't dicate your afr's. When calibrated they allow you to ask and recieve that afr. The rest makes sense to me. Your research paid off. IMO you have the best tuning device.

Poor word selection "purpose" perhaps capability would've been a better choice.

[Steve Cole]

While the SESPT does record data for 8 - 15 minutes depending on which unit you have that's not near enough memory to properly get much of a tune done. It takes about 20 minute on a Dyno to run through the VE tables once if you know what your doing. Street/closed coarse type riding is going to take more. I've also been told that if you unplug the SESPT from the bike you loose all the recorded data, if true, be careful and do not remove it until you hook up the laptop and get the data from it.

How does the SESPT show you what corrections are being made and if you've got enough data for a proper correction? There is a bit more to it than just a unit that records a small amount of data that may or maynot be useful. Also when using the SESPT it presets the AFR to a true 14.6:1 regardless of what you set it to in the program. It overrides what you place in the program and forces the CLB and AFR tables when you check mark the smart tune function. This is not close to what can be done with the TTS unit.

[Occam]

By the TTS, tune it yourself, be done with it, and RIDE

Additionally, I don't believe there is anything to add to the machine - you just plug in and tune.
It started as the SERT, but evolved down a superior path once they split from MoCo.
