As opposed to the hundreds of thousands of others that do offer such services?
They couldve gone after business with the whole "off road use only" clause and dont, so they wont now.
Sure, I thought about doing just that.
I would love to create a laptop program that can utilize the OBDII port and the only physical thing you would buy is a OBDII to USB cable (from Amazon), the rest is done strictly on the program itself. Id model it directly after ECMlink, which is pretty much stand-alone that utilizes the stock ECU as its bitch. Its fully fledged logging and tuning software, not these pick and choose PID's like SCT/Diablow/Etc through some junk handheld (or now your cell phone), and you can tune every parameter the ECU can change, from timing to using your CEL as a knock indicator to how long it takes your cabin lights to timeoff once your door closes.
The only thing stopping me (and others), is the fact Hyundai has made these ECU's extremely finnicky to communicate with and get any useable information through the OBDII port or be able to flash tunes through it. The two tune makers require the ECU to be in their possession to flash direct to the ECU using a special port that is proprietary (for obvious reasons). That, and im no programmer, so I have that going against me lol.
So if I was successful, im simply selling a program that lets you communicate with the ECU. What you do with it, is on you. I'm not selling hardware, its simply software. The onus is on you to use it in accordance with the laws and regulations. Id go as far as to recommend its not for use on vehicles driven in the CONUS, because who knows, I could sell a tuning program to someone in TX who is using it on his car that is in Mexico.
It's tough to make money just selling software.
