Actually the latest version (orange with big red button) allows a little better than an hour of record time.
I have taken 4 logged files and let "smart tune" do its job, and it works beautifully.

You have to look at your scenario, you got bags, could put it in there, you got a sissy bar, throw it in a computer bag and bungee it to the sissy bar. Or my latest vtunes were, wedged in between headlight and sissy bar up front with laptop open so I could monitor progress and keep hitting areas that were not getting sufficient data with laptop closed and out of my sight.
As to your laptop question, most will shut down when you close em, that's all part of the powersave feature, you have to go into power options in your system software, ie xp, vista, 7. Tell the computer to NEVER shut down when lid closed, never shutdown harddrive after x amount of time, and optional but never shut monitor off after x amount of time. It's all spelled out in the instructions in the tts software, you can handle it.

I read here that even though you can record forever, it keeps overwriting and you only get the last 10-15 minutes... but there may be new updates and then you can't always believe what you hear here...

I have yet to be bored enough to figure out the sample-capture rate which would aid in knowing how to fine tune above and beyond "smart tune".
Not trying to hyjack a thread, and I think we are on the same page, I am just trying to clarify so people don't go out misguided and make a purchase they later regret.

I was reading that there were some who thought they were capturing 45-60 minutes, but when they played back or looked at the data they found they were mistaken and only had 10-15 minutes worth. The data would not look redundant, you just would not have all you thought. Just wanted to make sure you weren't being caught in that trap. That was one of the big advantages of using laptop, you could get enough plenty of data to catch an anomaly in analysis and had much more data to tune with.

Looks like HD has improved the product to the point that the difference between its competitor is now more about how easy it is to use the data analysis tools and how many there are, that SEST won't do anything but 14.6 closed loop regardless of what you tell it, the amount of competent support you get on forums and from the manufacture, and a hundred bucks cash or so. There maybe a few adjustments still missing, but I don't think the backyard mechanic would miss them.

You can adjust it from 14.6 in the SEPST. Watch the DVD, it'll show you where to change it up.

You can adjust it to your hearts content, but the dyno guys that double check their work with quality sniffers found that the SEPST ignores your adjustments and just sets closed loop to 14.6 regardless. Us backyard so-called mechanics would never know as we have no way to double check that the bike is doing what we thought it was set to. Since your VEs are now more calibrated, the motor is going to run better anyway, just not exactly how you wanted it.

This is one of several reasons the astute tuner doesn't like SEPST, it just does its thing for closed loop AFR, and who know what else, you just can't trust it. Not that some of these tuners are cynical, its just that some like to double check, I think, because there are so many variables that interrelate. The smart tune and Vtune have the potential to save them some time, but not if you can't in fact adjust all the parameters.

You have to ask the SESPT manufacture why they chose to mislead the user about recording time and closed loop adjustments.. You may want to double check what the very latest SESPT version does.
