I have the Gen 1 box.

Do they have a trade-in deal on the Gen 2?
Are you sure that AEMTuner won't work with the Gen1 ems? There isn't anything that really states that anywhere on the forums or in the documentation. I saw some disclosure about the Gen2 and how it won't work with the AEMPro, but no information about the Gen1 and the AEMTuner.
They may want a more prominent disclosure if the AEMTuner isn't backwards compatible... but seeing that it can actually read the 1.19 cal, and supports Serial Port connectivity: I assumed that it would work fine.
