TunerCode can be found at
TunerCode, which is what the OP has purchased.
NismoTronic, which I am getting ready for the public release very soon, only supports the TunerCode firmware (bin file). And that information will be available shortly at
NismoTronic
The price of the software will be right in line with the registration fee of Tuner Pro, so probably right around ~$50.
So when it is all said and done, TunerCode firmware ($104) + NismoTronic Software (~$50) = ~$155 USD. And you get all of the features of the firmware, and a fully functional software.
You will be able to load a NON tunercode bin file, but you will not have all of the features available to you that are in the TunerCode firmware.
Also, if you are worried about using a normal tune file that you already have with TunerCode, Dave offers a conversion application which takes your current tune file and converts it to a TunerCode File so you don't lose your current tune.
