Updates! Anything not in quotations are replies from Trey. Thanks Trey. Things seem to be looking better and better. Especially the TCM stuff
Basically we offer the ability to fully reflash the ECU with any changes in data required, much in the same was the Technosquare flash is done. In addition however we add in new functionality to the ECU not normally there to allow the ability to tune/change certain engine tuning parameters such as the fuel, timing, rev limits, etc in Realtime or "on-the-fly". This is useful for the tuner to get an accurate tune without constant reloading on the flash data to the ECU. It's also useful for the end user in the event you want to quickly switch between high/low octane mapping, fuel economy mode, valet, anti-theft, etc without having to actually reprogram your ECU each time to do so. We're offering the same thing a traditional "flash" can do, put it in a handheld portable device so you can do it yourself, and add in the Realtime capability on top of that.
It definitely possible to eliminate any stumbles or bogs that caused by the factory tuning. The limitation of any reflash will be if a mechanical condition exists (ie: torque converter mechanical lockup, etc). We are also working on reverse engineering the factory TCM, though honestly work has just recently begun on this front.
Yes, we can. It is not a normal OBD2 or Consult-II logging parameter which is why it likely cannot be logged using other tools. As part of our reflash we add in special program code to the ECU that allows us the ability to read out this data to the AccessPORT or our tuning software.
Yes, we have a Consult-II we use in-house and we're able to duplicate its functionality with the AccessPORT.
As for TCU (TCM) mods, we are working on that as well. I believe we will be able to do this, though likely we'll initially release with ECU reflash capability only to suit all transmission types. We can then issue an upgrade for those that want TCU reprogramming capability.
Yes, there are multiple maps for different operating conditions/parameters. Many maps are used in conjunction with one another so its not always so simple as switching explicitly from one to another. Depends on the parameter in question. If necessary, we can program the ECU to lock the ECU into a single map with the AccessPORT.
Yes, you can change maps on the fly with only the AccessPORT. With the StreetTUNER software, you can fine tune your own fuel/timing maps as well as load them on the fly through your in-car PC or laptop.
Yes, absolutely.
You can but I'll be honest with ANY newer vehicle, the ECUs are designed to run a very dynamic ignition advance. They still have your standard ignition advance maps but there is a large amount of additional programming logic that runs behind the scenes and "fine tunes" the final timing advance used. Unfortunately the days of locking down your distributor to always run one ign advance are gone. You can program the ECU to stick within a "window" but I'll be honest in the fact that it'll be unlikely to force the ECU to always run the exact same ignition advance at redline. Instead, you'll likely see 1-2 degree variances based on what the ECU has determined optimal based on logic and sensor inputs.
Cheers,

Also, torque seems sevely limited below about 3300 rpm at which point, the torque suddenly increases markedly. This, in combination with the low stall speed of the TC causes the car to be a real dog off the line.

Like lets say that I go to the drag strip one night, and I load a nitrous map with the correctly tuned fuel delivery and retarded ignition timing, will I be able to load up an "economy map" for the drive home?

I've still not seen any conclusive evidence that the throttle body doesn't open all the way at WOT. Sharif states that the maximum voltage to the throttle body is only like 4.7 or 4.8 volts. It may indeed be open 100%, but no one would ever know unless they were datalogging and watching the butterfly valve with the intake tube off.
Even then, the results may not be reliable. If the tube were off, no air would be drawn the the MAF housing; and how knows how the ECU would react to a full throttle input with no MAF voltage.

Yes for the rev. It's listed above
Yes for the 100% TB. Just like TS does. Again, they say they can do everything TS can do and more
