Greetings to all active and energetic. I want to share with you my experience and earnings on chip tuning cars.
I will start with the fact that there is not much information on where to start for a newly minted chip tuner in the network. In this area, due to lack of experience, you can make mistakes, spend hundreds of thousands of rubles on equipment, while getting a small coverage of brands and models of cars, and pay off investments for years, biting your elbows.
In general, there are 2 ways to pour modified firmware into the car electronic control units of the internal combustion engine (“brains”, ECU, or just blocks):
- Recording through the diagnostic connector (aka diagnostic method, aka “by socket” method);
- Recording with opening the block (method “with modification”, “boot-mode”, BSL-mode, recovery mode).
I recommend to start with the 1st point, its charm is that it does not require a separate room, flashing can be carried out right on the street, and all the equipment will fit in a bag of medium size. In the future, if this type of activity is liked, you can proceed to the second point, here already without a room can not do without.
So, to flash cars through the diagnostic connector, we need the following equipment:
1) Laptop (netbook) with Intel processor, number of cores not less than 2, with installed OS Windows 7 Professional X86 (exactly this version) and a battery that provides autonomous work not less than 3 hours. Also desirable SSD not less than 240 Gb.
2) Elm327, the simplest device for diagnostics. The best option – Elm327, the description of which has the following: PIC18F25K80, single board 4MHz.
3) Kess device (aka Kess, aka Kes). Provides coverage of vehicles that were sold in Europe before 2016, not only cars, but also trucks, motorcycles, tractors and boats.
4) Piasini device (Piasini). Provides coverage, mainly Japanese equipment up to 2012.
5) Scanmastercan device, produced in Tula, provides coverage of all domestic cars and some foreign cars. Also this device can perform diagnostics of most cars, which also helps in our hard work!
6) Chipsoft j2534 mid adapter. Can work as a K-Line and Can-adapter. Necessary to work in tandem with firmware loaders, which I will list below.
7) PCMFlash. Represents a computer program-loader firmware, with a wide coverage and stable operation. Flash card with a license key. I bought it at ecutools.ru. PCMFlash comes in handy when you need to flash a car that is not covered by Kess, Piasini and Scanmastercan.
