That way you (and anyone interested in fixing cars) must either spend money on special software that decodes OBD2 codes, including ones that are manufacturer-specific, or spend money in authorized car service center. Personally I’d like to see all the data (emissions, engine performance, atmospheric conditions, seat heater use, tire pressure, etc. The pair made a great joint presentation; both were charismatic, using wit to navigate through the hardware, software, techniques, and goals you want to have in mind to jump into car hacking. In the event that is true would your home brewed EFI be accepted if it somehow would meet emission standards for that year? I’m at least partially competent when it comes to tech and embedded systems, but even for me, resetting the oil life sensor in my car is a bit obtuse.

The Car Hacker’s Handbook is not a book telling the reader how to control everything in three thousand pounds of rolling steel. This is how you begin to break down every bit of electronics, from cheap WiFi routers to broken Internet of Things devices.This is a guide on how to reverse engineer, exploit, and modify any kind of embedded system; cars are just the example. In the event replacement costs more than the truck is worth slap the carb on it and bring it to Kansas to sell the truck to someone here. The skills required to modify an ECU, snoop the CAN bus, or update your sat nav maps without shelling out hundreds are the same skills required to install OpenWRT on a weird router and install Linux on a hard drive the hard way. While you’ll never find a single volume filled with how to exploit the computers in every make and model of automobile, there is space for a reference guide on how to go about this sort of car hacking.

Where it can’t last forever I may go ahead and get the book anyway, as it may be useful for a vehicle I’ll own in the future or the vehicles of someone I know. Both were discussed by Craig Smith and Erik Evenchick during their talk on Car Hacking tools at Hope XI. The garage I take my car to is generally okay, they’re more honest than a stealership, but they don’t cross all their t’s and dot all their lowercase j’s. I’m expecting that in the future people won’t be able to fix or even sell their cars o their own because everything will be DRMed “for our safety”. Charlie and Chris had the opportunity to use a closed track for this demo for a tech journo, but didn’t.The classic car hack – removing the 27-series ROM from an engine control unit tuning a car with a pattern of bits and bytes is still covered. I own a 1969 Chevelle convertible, the car shown on the cover of the book, and can attest that there is not one computer, ECM or OBD port in the vehicle.

The clearest example of this focus on reverse engineering, instead of modifying cars, is Chapter 8, Attacking ECUs and Other Embedded Systems.Start the engine and idle the engine in drive for two and half minutes, with the A/C and rear defroster on if equipped.

You need to then wait “some period of time” (I’ve been told 24-48 hours), before going to inspection.If I had a desire to modify my car so I could read the value of the tire pressure monitors, instead of only being notified when one of them is too low, there’s nowhere for me to turn. Craig Smith is founder of OpenGarages and author of the Car Hacker’s Handbook which we highly recommend. The chapter on Attacking Embedded Systems goes through the usual tools – the JTAGulator, using an STM32 Discovery board for its SWD functionality, to side channel analysis with the ChipWhisperer.
