On this first shot, notice that this is an excellent shot of the main dash along with some of the fun configuration screen stuff. We indicate a "CAL ID", which when the car is started, the CEL blinks by that amount of times to let the user know what map is loaded onto the unit.
This screen is also where we adjust the top speed limit from 124 to 135.
VsADJ accommodates for different sized wheels or tires that effect the speedo reading. This helps correct it.
Guardian Mode is something we can enable to help the end user from blowing their car up. It can be set to alter AFRs in the event of an excessive lean or rich condition, coolant temp engagement point, a max RPM and a max TPS
2step is also controlled in this screen. Self explanatory.

On this screen is where some of the magic happens! 
This is the AFRBase table, where the end user would enter their desired AFR based upon RPM (top axis) and cylinder pressure (side axis). No pulse width calculations. No BS! No duty cycles! Just enter the AFR and be done with it. It does the rest from there. I will demonstrate on a WOT run I clipped how accurate it is.
Notice the 3D table at the bottom of the fuel map.

This screen is where one controls the ignition timing. In this breath the unit works like say an FIC. It lets the stock ECU calculate the final value of timing based upon multiple sensor feedback, and you can either not touch the value, retard or advance from there. Simple!!!

Now for some mind blowing datalogging!
There are several preset tabs that one can view select parameters like a FUEL tab of only fuel stuff or an ignition tab....You can even add other fields to the predefined fields on here. Say you want ignition timing as well to the fuel tab, you can add it. Say you want to make your own tab, you can even do that!
On this particular pull, note we where at 5084 RPMS, 205.6 g/s of MAF air flow (about 10.5-11 PSI), at WOT for 4.4 secs, 92 MPH, Pedal position of 91.8% and TPS of 100%.
This is the interesting note....After speaking to a few Toyota engineers whom wrote the code for the stock ECU, they had indicated that Toyota only opens the throttle plate about 82-85%, and not 100%. He has stated this is VERY standard on almost all newer models. So the 100% you are seeing in TPS is actually only 82-85%, but if that is the allowable max by the stock ECU, then that is 100%. We all knew this was the case, but now we have EXACT answers.
Notice, we where pulling about 5 degrees of timing in this pull too at this exact moment. With Spark.SparkAngleY at 18.1* of advance, we told it to pull 5* after that calculated value, hence the output on channel Spark.SparkAngleY being 13.4!

This is yet another awesome datalogging screen shot, but this time we are flexing the golden fuel injector control.
Note the commanded AFR (Fuel.AFR.CMD.Y) of 11.5:1. Note Sensors.WRAF1.Y being 11.48-11.55:1 AFR. How is that for control?!!?! This was also verified by an external AEM UEGO as well, which was pegged at the time of 11:4 or 11.5:1.

lol this must look like the swahili alphabet to you moises...but to me this unit screems buy me....at the low suggested price of 1500 
yes paul i said it hahahahaha
but wow that afr table makes tuning a breeze no more fuel trim inputs

and I'll wait til someone blows their motor, crashes, etc and you buy it martin.... then you crash or blow your motor, and when your car burst into flames I will swipe the unit for free and leave you inside!!!(Im just playing martin 
) and the legacy can continue from there.
So many great products everywhere now for the TC. YIPPEEEEEE
