Interesting topic. Obviously greed is alive and well in the tuner community. While young computer hackers are schooling the OEM's on their own hardware systems. Suggest completely skip begging from tuners and software manufactures, and going straight to the Defcon hackers community who've recently found the auto market a new playground. The ones who handed Chrysler Fiat [along with Tesla] engineers their nuts in a bag last month. They eat this stuff up, and post how too's and source code for bragging rights.
Offer up a small bounty or prize in the car hacking forums, some 14yr old will get it done. Especially if you say someone else has it and won't share... lol
