Enlighten me please. When you talk about the PV "auto tuning", are you talking about the device actually altering the base map all by itself, or are you perhaps talking about the device collecting data that you can use to alter the map yourself using their software? The TTS and SEPST have the latter system as well, but that is not "auto" tuning, that is data collection and manual tuning by the owner. True auto tuning, if such a thing really existed, wouldn't require any input from the customer at all. BTW, real tuning involves a lot more than just fuel mixtures.
As to the capabilities of the various brands, I'll leave that up to someone who has personally used them all to hash out. But I stand by my previous statement that there is no such thing as a true "Auto Tune". Perhaps if folks would stop using that BS marketing description of the products it would help reduce the misunderstandings and vitriol involved in these threads. The only thing truly automatic is death and taxes.

Autotuning with the PV is very different in practice than with TTS or SEPST. I've completed dozens perhaps a hundred tunes as I've experimented with various setups. The fields that are modified would be very familiar to anyone that has done dyno-tuning however the user doesn't have to view any fields at all to autotune unless they want to.
From a process POV its extremely easy and can be done on the road and without a laptop. I have the PV mounted on my handlebar just like a GPS. When it's not tuning the rider can view engine temp and many other parameters of the bike's performance in "realtime".
1) Autotuning on a PV is accomplished by pressing a single button to autotune an existing map (6 maps can be retained on the PV at any one time). The PV then automatically flashes a new map to the bike. This new map is identical to the original map except that 4 degrees of timing has been removed from across the Spark tables and the AFR has been moved to closed loop across the entire map.
2) Just go and ride. Enjoy time in the saddle instead of letting your bike crank up hundreds of miles on a dyno. The PV collects data and that's all it does at this point. You can stop and restart and collect data as you wish.
3) When you've completed your data collection (20 mins of variable load and riding conditions is generally a good data collection to start), you simply press another button on the screen to "export learned data". This will create a new map file to be stored in one of the 6 slots on the PV. This exporting function will restore the map to its original AFR and spark settings and update the file with new VEs that will cover all cells where enough data was collected in VE cells from 20-100KPa and from 1000-7000rpm
4) Flash the new autotuned map to the bike and ride. In almost every case the change will be noticeable unless you already had an efficient map to start with. That's all there is to it.
With the PV you can autotune and never even leave the saddle however you do need to stop and flash the new map to bike.
If you're more knowledgeablea about tuning, you can dismount the PV, bring it inside, connect it to a laptop and do more extensive analysis of the map and the bikes performance using WINPV which comes with the device and is also used to update the map library and the firmware on the PV using the internet. Its very slick. If you want to "know nothing" and just tune, you really never need to connect to a laptop other than updating files as new services are released. Or if you want to know more about what's going in in the tuning process, you just bring it inside and analyze to your heart's content using your laptop in the comfort of your easy chair.
