The upside (depending on your perspective) of the modern automobile’s use of computers is that it offers things like traction control, blind spot assist and radar cruise control, not to mention smoother transmissions and engines that don’t knock. The downside, as many of you backyard mechanics know, is that it’s now nearly impossible to work on your own car without an advanced degree in nerdism.

Auto Alliance, an association of 12 of the largest car manufacturers and a congressional lobbying group, now wants to make it illegal for you to work on your own car. Auto Alliance is using a section of the Digital Millennium Copyright Act, saying that tinkering with your car constitutes a copyright violation.

Luckily, the Electronic Frontier Foundation has taken control of the reins for enthusiasts, looking for exemptions that would allow access to the inner workings of components.

Automakers are saying that modifying Electronic Control Units could lead to security vulnerabilities or worse, equipment failure. It would also void any warranty protection. The EFF insists the automakers are only interested in profit, and that they want to sell software upgrades for themselves, blocking many tuners out of the business.

Ford has already filed a lawsuit against a New York-based diagnostic equipment manufacturer for trade secrets, and GM says that not limiting access to the ECU and subsequent coding “would offer a serious, and potentially fatal, blow to the future of automotive telematics.”

Jake Lingeman has been with Autoweek since 2006 and career highlights include driving the Silverstone Circuit in England, taking the Corvette ZR1 around Road Atlanta and going to the 24 Hours of Le Mans. When he’s not writing about, driving, working on or thinking about cars, he’s reading liberal books and playing video games. In his opinion, the best new car in the world is the Ferrari 488 Pista. The Ford Shelby GT350, the Nissan GT-R and the Porsche 911 GT3 are favorites too. He owns a 1963 Pontiac Star Chief, a 2014 Ford Mustang GT and 1989 Mercedes-Benz 560SEL.
