Check: pcmtuner module 53 BSL instruction

Flex and Foxflash can do it on bench but if written wrong file and do it in boot. If you cannot do in BSL then not possible to recover eeprom/flash.

Example: Audi A7 2012 2.8 fsi simos 8.6 unlock, after read/write simos8.6 with pcmtuner successfully. all resistor 1 kom How to work with blocks that require unlocking (PCR2.1, SIMOS8.6): 1) Check the current lock status in the car, if the check is disabled, you can go to read-write, otherwise follow the instructions 2) Remove the unit from the car, open it, transfer the processor to BSL mode using the connection below (PCR2.1, SIMOS8.6), the work as a whole as in the package 53 (you can use tools like powerbox, and you can do without them) SIMOS8.6 Unlock pcmtuner pinout Red — +12, Black — GND, Yellow — CAN-HIGH, Blue — CAN-LOW 3) Choose "SIMOS8.6 (EEPROM/UNLOCK/BSL) or PCR2.1 (EEPROM/UNLOCK/BSL)" depending of ECU type 4) Click Identification — save ECU data somewhere in a text file. 5) Click Read — save the EEPROM 6) Given that EC...

How to Find Bosch ECU Serial Numbers and Correct Pinouts

 Here is basic post for people asking basic questions, apparently now on high demand since we have gathered again new members in our ECU group . So you got bosch ecu in hand from car and how to figure out how to identify it and what pinout to use? On this case we can randomly take one bosch ecu that we will identify. So all bosch ecus start with serial numbers 028… 026. We just head to bosches page next https://www.bosch-repair-service.com/ Here you search by oe or bosch number, i have random bosch ecu here and it’s 0 281 014 544 and bosch page ends up with a result. We can see its edc16cp35. Now there are two ways. Either to search in foxflash bmw / edc16cp35 for pinout. Or we head to ecu pinout page and figure out pinout from there. One of the best online pinout catalogs can be found at ecu desing, So save webpage https://ecu.design/ecu-pinout/ Copy address and head out there. Type in edc16cp35, bmw uses two processors in this one mpc 562 and mpc564. Pinouts jus...
