PCMTuner VAG Simos PCR2.1 Unlock Instruction

 Question:

Can pcmtuner read and write vw pcr2.1 obd or bench? Can PCMtuner read and write Simos PCR 2.1 without unlocking, or it can bypass the lock? Or if can unlock it automatically. Thanks.

Answer:
Must unlock first in bsl before read/write.

BSL unlock it, then OBD read it.

 

Instruction PCMFlash Module 57
SIMOS 8/10/11/PCR2.1
Information and PCR2.1 example

Information

PCR 2.1 were installed on various vehicles group VAG diesel engine 1.6TDI requires BSL unlocking.
Please note: where available real reading, only the calibration area is subtracted (not the full dump), in this case, pay attention to the version of the calibrations coincided with the current version of SW, otherwise. Work very carefully, only SIMOS 8.1/8.2 ECU can be restored via module 53 (Tricore BSL). The rest will have to change to new ones.
The current lock status is displayed when the unit is identified (works for SIMOS 8.4, 8.6 and PCR2.1):

Module: VAG: 2.8L V6 FSI (SIMOS8.6)
Identification
Catalog number: 4G0907552F
Software version: 0005
Hardware number: 2.8l V6 FSI CHVA
VIN number: WAUZZZ4G3BN******
Encoding: 1A250034042601020000
Programming: 2
ECU type: SIMOS8.6
The digital signature verification check: Disabled

If the check is disabled, you do not need to unlock it.
The essence of the unlock-modification of the external EEPROM installed in the unit. So before unlocking it is suggested to read EEPROM and save.
For ECUs PCR2.1 loader displays the current lock status when identifying in BSL mode (if set).

Serial number: 41048482-19E0A315-82060010-240EFE00
Hardware number: EV_ECM16TDI
Part number: 03L906023KN
Software version: 9056
VIN number: WAUZZZ8X4BB******
The digital signature verification check: Disabled

Serial number: 41848480-13C09713-82160010-270A0700
Hardware number: EV_ECM28FSI
Catalog number: 4G0907552F
Software version: 0005
VIN number: WAUZZZ4G3BN******

Each press of the “Initialization”button in BSL mode changes the lock status to the opposite. So be careful what you do.

How to work with ECU that require unlocking (PCR2.1)

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 pictured (PCR2.1,) the work as a whole as in the package 53
3) Choose “PCR2.1 (EEPROM/UNLOCK/BSL)”
4) Click Identification – save ECU data somewhere in a text file.
5) Click Read – save the EEPROM
6) Given that ECU is blocked, we perform Initialization once for PCR2.1 get something like this displayed):
Module initialization
Entering programming mode
Transfer bootloader
Examination
The digital signature verification check: Disabled
Done
On this ECU BSL complete. remove resistors, and ECU can be sealed closed and put in the car. Then read write as normal.




FYI:pcmtuner new update PCR2.1 unlock instructions, click OBD will see that.

PCMTuner Unlock Audi SIMOS 8.6 in BSL Mode

 SIMOS 8.6 requires unlocking in BSL mode by the appropriate module. BSL is usually boot mode for unlock. Same as PCR2.1 . 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

Image
 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...

FoxFlash Read and Write Volvo Denso MB279700-9xxx

Image
 Foxflash Volvo Denso MB279700–9xxx works perfectly, just follow the steps of foxflash , reading, unlocking, and writing all done on the bench. PROCEDURE: 1 — Read the Ecu AND unlock the Ecu 2 — Write the ECU READING AND UNLOCKING: Connect the following pinout using the multifunction cable. Start the driver: CAR > VOLVO > TOOLS VOLVO >UNLOCK DENSO MB279700 9641 SH72546R CAN Click on the READ FILE button to read the file. After reading, click on the UNLOCK button to unlock and enable the writing of the control unit. WRITING: Now it will be possible to reconnect the control unit to the car and write the modified file via OBD. Use the following driver: CAR > VOLVO > Model >2.0 DENSO MB279700 9641 SH72546R CAN Alternatively, you can WRITE also the ECU on the table using the pinout on the next page. Note: Compared to the read pinout, the CAN line is moved. FOXFLASH PINOUT FOR WRITING: Just follow the foxflash instructions: read file 15 min, unl...
