Subsequent Work For Diagnostic Scopes

Information 

• After removing, installing or replacing, perform the "Sensor wheel adaptation" function using the PIWIS Tester. 
• To actively teach the adaptation, perform an adaptation drive together with another person. 

1. Reset sensor wheel adaptation:

   Connect PIWIS Tester  to the vehicle.

   Select Engine electronics (DME) control unit. 

   Select Maintenance/repairs  tab.

   Perform Sensor wheel adaptation reset. 

   Follow the instructions on the PIWIS Tester. 

2. Perform sensor wheel adaptation with an adaptation drive  .

   Get a second person to check the PIWIS Tester  while you are driving.

   Select Engine electronics (DME) control unit. 

   Select the "Actual values/input signals"  tab.

   Select the group "General". 

   Select the actual value "Engine speed"  .

   Select the "M_Misfiring"  group.

   Select the actual value "M090_Sensor wheel adaptation"  .

   Value "1" = adapted and (value "0" = not adapted).

3. Perform sensor wheel adaptation with an adaptation drive  .

   Condition:  Engine at operating temperature

   Perform adaptation drive until M090 actual value displays "1" → Adaptation is complete. 

4. Procedure:  Adaptation drive:

   992, 982 GT4/Spyder/GTS 4.0: 

   1. 4.1.1 Drive smoothly for more than 1 minute.

      Generate a minimal load → Slight acceleration or slight ascent.

   2. 4.1.2 Speed at least 65 km/h (40 mph).
   3. 4.1.3 Engine speed → 1200 and 2000 rpm.

      991, 981, 982 (4-cylinder engines): 

      Drive with brief acceleration.

      1x Overrun phase (accelerator pedal not pressed for 7 seconds, no fuel injection).

      991 GT3 variants and Speedster 

   4. 4.5.1 Performing fast adaptation:

      1x Overrun phase (accelerator pedal not pressed for 7 seconds, no fuel injection)

      Engine speed 3, 500-1, 800 rpm

   5. 4.5.2 Detailed adaptation procedure:

      Drive with brief acceleration.

      Overrun phase (accelerator pedal not pressed for 3 seconds, no fuel injection)

      Engine speed 3, 500-1, 800 rpm

      Perform the following procedure at least 11 times until the adaptation status changes.

      992 GT3 variants, 982 GT4RS: 

   6. 4.6.1 Performing fast adaptation:

      1x Overrun phase (accelerator pedal not pressed for 7 seconds, no fuel injection)

      Engine speed 3, 000-1, 300 rpm

   7. 4.6.2 Detailed adaptation procedure: 

      Drive with brief acceleration.

      Overrun phase (accelerator pedal not pressed for 3 seconds, no fuel injection)

      Engine speed 3, 000-1, 300 rpm

      Perform the following procedure at least 11 times until the adaptation status changes.
