Zed-Full - OBD - программирование ключа BMW 5 series, 2008 год дамп можно сохранить на ПК (через ПК приложение Zed-Full). Описание к программному продукту "CAN OBD version 1.0". Инструкция и программное обеспечение дамп редактору версии " Dump Editor version. *Предистория*. Вот уже почти 2 года я пользуюсь китайским Super Mini ELM327 V1.5 Bluetooth OBD-II адаптером. Недавно в моих руках так же побывали . Нужно считать прошивку с еепрома, вставить в программу Audi VDO Crypto раскриптовать. И вот тогда можно подмену дампа сделать обратно закриптовать и записать в еепром. Либо через обд залить.. В то же время последняя разработка нашей компании чип-тюнинг бокс ProRacing OBD подключается к диагностическому разъему OBD2.
Basic Guide to ECU Map Chip Tuning. Basic Guide to Do- It- Yourself ECU Map Chip Tuning (Using HEX Editor)This is a brief introduction on how to tune a sample car map file using a good ECU HEX editor like TOAD. NOTE: This is only a very brief introduction to tuning. There are many forums online on how to edit map files. STEP 1: Download the stock ECU load from the vehicle. This image is the raw data from the ECU memory and is the application and Operating System code for the ECU. It controls how the car runs. Above the code area you will find the Constants and Maps, among other things. Take a look at the figure below..
In the hex dump window you see a series of highlighted bytes, 4. A 0. 0 0. 0, and in the Inspector window you see "Float 2. This is showing a map or constant value, in 3.
The next series of 4 bytes, 4. FA 0. 0 0. 0, is a value of 5.
A value of 0. 0 0. Notice there are lots of 3. This is part of a table. The 2. 0 values shown are: 2.
The values 2. 00 and 5. RPM based on the magnitudes (RPM would not normally be lower than 6. RPM values used in a lookup table or map. What is a Map? Look at the array below.. The numbers in red represent RPM values, the green numbers represent Mass Air Flow and the numbers in the yellow matrix represent fuel injector pulse width. The longer the injector pulse the more fuel gets injected into the rotor. To find this table you would look for ascending RPM values, ascending MAP values and many fuel injector pulse values, RPM X MAP numbers, in this case 1.
X9. This is a purely hypothetical MAP for illustration only. RPM MAF 8. Going back to the ECU hex dump, the ascending RPM numbers could be the start of a fuel map, or it could be a timing map, or possibly a map to control oil injection, at this time we don't know the definition of that map. To find a Constant, you need to know what to look for. An RPM limit would be a 3. You would do a search for "4. C A0 0. 0" to find all values of 9. Pick one and change to 8. RPM limit. Not all values are stored as floats, there are also single byte values of 0- 2.
Once you take a look at the MAP area in memory, you will see it's nearly all floats or byte values. On the last note.. Even though chip tuning is possible with any ordinary HEX editor (as described above) — the fact is it can be very time consuming, tedious and error- prone.
*Предистория*. Вот уже почти 2 года я пользуюсь китайским Super Mini ELM327 V1.5 Bluetooth OBD -II адаптером. Недавно в моих руках так же побывали. Есть много способов чтения дампа — можно через OBD, у кого есть дорогостоящее оборудование, можно выпаивать процессор, но самый доступный это внутрисхемное программирование..
That's why if you're serious about car ECU chip tuning — you want to look into dedicated ECU chip tuning software like TOAD. Software that not only provides HEX editing capabilities, but can also visually map out cars ECU map into sections.. This means you can tune a map in minutes vs. ECU chip useless.
