Calvin's a bright guy with other irons in the fire.
So what, an obd2 app finally? Or...just custom jets & floats for a boost-capible Holley 650 double pumper?? I'd guess it will just be shit for k-series or s2k stuff.
Although I think Calvin is a little paranoid, I can understand. The problem is that no matter how much effort you go though, someone will defeat your security. I recall the big shit about the first PS2 chips. The first "real" chips used Actel copy-proof chips in which internal traces get shorted after production. Yet...they still copied them.
And IMO until he stops using a basic chip emulator, it will never be fully secure.
