Spend some time looking at ECUs other people have already figured out, often there are commonalities, regions tend to use the same chipsets, you'll see a lot of SH's and so on in Japan for instance, PowerPC/motorola is common in Europe, renesas, Mc6811's are popular in older cars too. Sometimes the BDM is disabled, or there is some internal read out protection, side channel attacks or piggyback from someone else.

Look for JTAG/BDM ports, they're usually close to the CPU which is often the largest chip, but not always, there might be an FPGA or CPLD thats larger, XTALS(crystals) are often a good way to spot a CPU they'll be close by the chip and nearly always have two capacitors close by, sometimes a series resistor. Look for external flash chips, these are usually the easier ones to get into, you pop off the chip and read it with a reader, dataman have a good one, there are lots of cheap ones too, if you're messing about at a hobby level its fine. The OEM will want a guarantee of a future supply chain.Ĭhanges often involve dedicated features like security, TPU, or adding in features that might be hard/slow to do in software. Some chips have markings on them for the OEM, there are different reasons for this, supply chains and changes internally to the chip, but often the chip pinout is the same or similar, identify with xtals and gnd/power lines. Research the chips, a lot of them, are already out there. Buy a spare ECU if you can from ebay or the scrapyard, take it apart. Realise that some people feed their kids and pay their mortgages do that, and they'll point you in the right direction but don't expect them to give away stuff that is their business, especially if you're just knocking off someone elses work.Īlso accept that there are just a lot of people who get into it for fun, and they put a lot of work into and they get burned out by help vampyres, the better ones will usually get offered a job with some tuning company. People took the time to help out, say something. If you get info, even if its not super helpful, say thanks or reply back. Google as much information as you can, find out the ecu model number, don't just say its from a 1999 ranger, there are different models of ecu's and firmwares, different countries call different cars the same models.īe honest about what you actually want to do, tune the car, learn, or just too cheap to pay for a tuner or someone to clone someone elses work.īe realistic in your goals, it takes a long time to reverse engineer a new ECU properly, you can get by with poking a bit here and a bit there. It's like a lot of things the more research you'll do the more people will help you out. I guess my post is a lot more RE than tuning.but maybe i'll add to it when i get some time to think about it.

Mod note: Most of my time is taken up building hardware, if a better person for the community comes along I would be willing to hand over the sub.
Our long term goal is to become the most technical car subreddit. We would also like to encourage the use of Open source hardware and software. The car hacking community is alive but fractured and decentralized, let's start by aggregating all of the many projects, and hackers. Discussion is not limited to the ECU, post any hacked DIY Aero, powertrain, suspension, or other car topics the community might like. New age hot rodders, ECO modders, security researchers, the curious, the paranoid, and the tinkerer are all welcome. This is a place for people interested in taking back control of the car they own or keeping others out. However, this brain is a closed, locked-down black box. While the engine is the heart of the car, the ECU has become the ever-evolving, all-knowing brain.
