PCMtuner usage report: Successfully read BOSCH MEV17.2.1 on Bench

 This is a tutorial on how to read 2012 BMW 3 series ECU with PCMTUNER Tool on bench. Due to data loss, we should get ISN from EEPROM to repair CAS data. For other cases of ECU reading may follow the same way.

Procedure

Step1. Connect ECU to PCMTUNER

Start PCMTUNER software to search ECU model. (Users can send customer service ECU outside label to get corresponding specific model if in need).

In this case, it's BOSCH MEV17.2.1.

Check ECU Model & Connection Diagram

BENCH >> INSTRUCTION

Here we can check if the selected ECU model is correct.

And connect PCMTUNER to ECU according diagram.

*It should be noted that wire connection is based on instructions rather than colors.

Eg. 1a/1b represents ECU position; A1/A4 represents wire tag.

Record MCT No.

It's TC1796, in the connection instruction.

Step2. Read ECU

Go into "READ and WRITE" to select options;

ECU: MEDE17(TC1762/1766/1792/1796)EEPROM

Click "Read".

Would you like to use automatic power control (L-Line)? Yes.

Reading data successfully.

Save EEPROM data.

Now we can find out ISN in EEPROM to repair BMW data.

This is how to use PCMTUNER ECU Programmer to read BOSCH MEV17.2.1 on bench.

What's wrong with PCMtuner VZ-Performance unable to log in?

 I can use PCM Tuner, but I can't access vz-performance and get the error prompt 'Wrong username or password'.

The solution offered by obdexpress.co.uk engineer:

Install pcmtuner software and finish registration first.

Then contact our customer service to activate your register email.

After activation, you will get one account to access https://support.vz-performance.com and https://www.tuner-box.com.

User Name= registered Email, Password= Software Serial Number

The serial number (password) can be found at the bottom left corner of PCMTuner 1.23 software.

Note: These two website account were different before. But from April 19th, 2022, activation only generates one user account.

• tuner-box account is for create ticket support tool user.
• Vzperofromance is for tuner support. It has VR file and many damaos there.

The factory will synchronize the serial number in the next update.
It will fix this bug. So users don't need to activate vz-performance separately.
Please do activation until the next software update is released.

For any problems, please feel free to contact our customer service(obdexpress.co.uk).

PCMTUNER or CGDI FC200 ECU Programmer, Which to Buy?

 2022 best ECU programmer: PCMTUNER or CGDI FC200, which one to buy? Both tools were well received since released. Which one is more recommended?

Obdexpress.co.uk engineer suggested:PCMTUNER is used to program gearbox & ECU more while CGDI FC200 works for BOSCH ECU more. It’s mainly depended on the supported ECU coverage. Both are professional ECU tools. Any questions welcome to contact online service for a check.

However, if you want to know more differences, move forward. Below is a comparison table to let you be clear at a glance.

PCMTUNER vs. CGFC200

Differences

PCMTuner supports to work on Bosch, Magneti Marelli, Continetial or Siemens while CG FC200 only supports Bosch and certain old Siemens.

PCMTuner supports paid virtual reading online while CG FC200 does not.

PCMTuner has its own tuner account for paid dpf, egr, adblue off and remap while CG FC200 does not.

PCMTuner supports to do checksum while CG FC200 is only workable online during subscription period.

CG FC200 has more protocols than PCMTuner.

CG FC200 support multi-languages while PCMTuner only supports English & Russian.

CG FC200 supports to read & modify BMW ISN, VIN while PCMTuner cannot.

PCMTuner is cheaper but cannot do BMW ECUs(EDC17xx, etc.)

Conclusion

For mainly doing ECU chip tuning or programming more ECUs, PCMTuner is recommended & good-value.

For reading & modifying BMW ISN or programming mostly Bosch ecus, CG FC200 is recommended.

Anyhow, it’s never wrong to choose according to needs. For more Car ECU Programmers, please visit www.obdexpress.co.uk

ktm bench 1.20 tune 320d BMW with Bosch edc17cp02 ecu

Car model and ECU type: 320d bmw with bosch edc17cp02 ecu

 

Purpose: Read and write ECU and start the car

 

ECU tuning tool: ktm bench 1.20

 

Problem:

I connected power can and gpt pins on the corresponding numbers made a read but selected flash from the

(71) Bosch med17 tc1766 flash. It crashed during erasing and writing around 7 percent. No longer able to detect through gpt pins i opened ecu soldered boot wire onto pad inside and if i select (53) tc1766 micro 1504kb i can read and write successful but car will not start has lots of faults on the dash.

How to solve?

When you failwrite file you erase 18000-1BFFF area. It's BOSCH service loader area.

You must select 53 module, use write function and select off optimization write, select write all, include, service areas and [Other] option in ECU selection and not correct checksums.

 

You must select raw write. Not MEDC17. And your reading is enought to recover your ecu.

Read your file after crash and check 18000-1BFFF area.

 

53 module of your ktm bench 1.20 clone tool to use to check your file after the crash.

You must read your bad file in BOOT mode. And compare it with your original read.

Good luck!

Solved: MB SD C4 Plus prompt "the data is incorrect"

 Mercedes MB SD C4 Plus Connect Compact 4. I have several problems.

Although I already bought a Windows 10 key to run the system.

 

I start the Config Assist and try to read out the hardware ID as prescribed.

 

It doesn't find anything and runs for hours with no result.

How to fix?

Uninstall all hidden virtual drivers. I Had the same problem.

 

We connected a newer car to diag and xentry always shows Data is incorrect. Older cars works well, because it opens in DAS.

 

Hope it helps!

Ktag clones the old edc17c41 BMW F10 to the new ECU

 Have edc17c41 bmw f10 with old ecu is dead, d.. and I buy a ecu with the same part number. i can read with ktag in gpt , try multiple times.. no luck. The next plan is to clone from the old to the new.

 

What to do:

If the old ECU is okay, with KTAG, do a full backup of the old ecu in GPT.

Then restore to the new one.

 

If the old ECU is dead, must read from CAS ISN and written in ecu ISN.

CAS 4 READ WIT HEXTAG.

or read eeprom from CAS, read flash and eeprom from ecu. and send to someone who can send it to you and will give you what you need to write in ecu.

 

If the car won't start, and have error 276F00 electronic immobiliser pretection against tampering, no authentic response received. my car is manual, the donnor car is automatic.

 

--- You need to decrypt cas for get proper isn - need read a key at least ( proper soft existing) or if U get some locksmith bmw equipment - make a decryption by key

 

It is coding (manual OR AUTOMATIC) issue.

Cas4 is crypted - password ISN from ECU(not available) or key - without This - no do anything - no sense.

 

If you have the key, that's good, please use cgdi BMW or vvdi prog. You need to read ISN from CAS by CGDI by OBD ( look like it has to be supported) ( you got FUll BACKUP UR CAS, if no make it, Plus do it with ,at least, battery charger):

 

Put cas back to vehicle, connect power supply(charger) and press read ISN from cas(key inside of vehicle or inside of cgdi), ignition turned ON.

 

I did it for cas3+ and never did it for CAS4 but by CGDI, it is supported.

 

==================================================

Disregard previous info - as I said - i never met CAS4 and Ur case - it is good -CAS not crypted.
Previous to get ISN from crypted Cas.
new Scenario:

as Change ISN in DME need physical connection for my equipment an i do not know checksum algo i made Vin Correction and ISN correction - BUT NEED TO CHECKSUM eeprom before writing.(Ktag - if support(automatic correction))

I have change ISN in Ur CAS - as U got full backup - U can write CAS4 eeprom to cas and try with ORI ECU eeprom file

If car start U need to programm ECU by ista - as U got manual tranny it is more easy about EGS ISN (not needed to reset)
and U need injector coding too.(numbers from top of it)

 

Pictures - isn from ori eeprom engine ecu. And ori and modified cas4

 

This post shows a guide on how to do, whether it can help you solve the problem depends on the specific conditions.
