Problem: Today I failed to read Audi A5 Bosch Edc17cp04 ecu with pcmtuner on bench. Try bench connection pinout from pcmtuner, failed. Using bench module 71. Any idea?
1.Try the wiring diagram from dimsport, reconnect and read again
EDC17CP14 bench pinout
EDC17CP04 bench pinout
In bench select the correct eeprom family for identification.
Some succeed in reading edc17cp14 on bench
If failed, try OBD mode.
But for older CP04/CP14 it’s is better to use OBD protocol module 50 as EDC17U01/U05/CP04/CP14 use can communication.
WITH ECU IN CAR :
1. ID ECU INFORMATION
2. SEARCH VZ-PERFORMANCE FOR VR FILE
3. MODIFY FILE
4. WRITE FILE
There is no “vr mode”
Vr simply means the file is virtual and not from the actual ECU
1. After identified you have hw and SW numbers
2 go to vz-performance and search for the file you need with the details
3 download the file and modify for tuning etc
4 write file via obd
1). Edc17cp14 via obd very good with pcm tuner
Connect charger adds extra safety 13.8v+.
If you have removed the cp04 cp14 ECUs from cars, connect pcmtuner with a breakout box tricore cable to read ECU via OBD on bench.
