⚠ WarningFor the CR61_470 V1 and V2 variants (EDC17CP57) the manual recommends using the CB403 cable. Careful: the pins change between variants that look identical (CR40 and CR41, for example), so identify the exact ECU designation first.

Procedure

  1. CR61 (EDC17CP57, Bosch TC1793): T96 PIN 39 - PWM; T96 PIN 35 - PWM; T58 PIN 3 - 12V+; T58 PIN 2 - GND-; T58 PIN 15 - IGN; T58 PIN 41 - CAN H; T58 PIN 54 - CAN L.
  2. CR42 (EDC17CP46, Bosch TC1797): T96 PIN 35 - PWM; T96 PIN 39 - PWM; T58 PIN 3 - 12V+; T58 PIN 2 - GND-; T58 PIN 15 - IGN; T58 PIN 41 - CAN H; T58 PIN 54 - CAN L.
  3. CR6 (EDC17CP10, Bosch TC1796): T96 PIN 39 - PWM; T96 PIN 35 - PWM; T58 PIN 3 - 12V+; T58 PIN 2 - GND-; T58 PIN 15 - IGN; T58 PIN 41 - CAN H; T58 PIN 54 - CAN L.
  4. CR41 and CR41R (EDC17C66): T58 PIN 3 - 12V+; T58 PIN 6 - GND-; T58 PIN 15 - IGN; T58 PIN 40 - CAN H; T58 PIN 53 - CAN L; T96 PIN 41 - PWM; T96 PIN 44 - PWM.
  5. CR40 (EDC17C43): T58 PIN 3 - 12V; T58 PIN 4 - GND; T58 PIN 15 - IGN; T58 PIN 41 - CAN H; T58 PIN 54 - CAN L; T96 PIN 35 - PWM; T96 PIN 39 - PWM.
  6. CR43 (EDC17CP60): T58 PIN 5 - 12V+; T58 PIN 4 - GND-; T58 PIN 15 - IGN; T58 PIN 16 - 12V; T58 PIN 41 - CAN H; T58 PIN 54 - CAN L; T96 PIN 38 - PWM; T96 PIN 89 - PWM.
  7. CR61_470 V1 (EDC17CP57, CB403 recommended): T96 PIN 35 - PWM; T96 PIN 39 - PWM; T58 PIN 2 - GND; T58 PIN 3 - B+ 12V; T58 PIN 15 - B+ 12V; T58 PIN 41 - CAN H.
  8. CR61_470 V2 (EDC17CP57, CB403 recommended): T96 PIN 38 - PWM; T96 PIN 87 - PWM; T58 PIN 2 - GND; T58 PIN 3 - B+ 12V; T58 PIN 15 - B+ 12V; T58 PIN 16 - B+ 12V; T58 PIN 41 - CAN H; T58 PIN 54 - CAN L.
  9. With the wiring made up, power the bench (ZN074 recommended for the ZN051 DS Box), open the FBS4 Manager, select ECU and press "Info" to confirm communication before running "Save" or "Virgin".
