Throttle Body Calibration Porsche 997.2 987.2 957 Siemens SDI3 SDI4 ECU

After you flash your vehicle, you need to do a throttlebody adaptation and clear the codes.  There are several ways to do this.  The first is by utilizing the iFlash Diagnostics tools function.

1. Once the flash is completed and the ignition is off, turn the car back on with all lights on the dashboard and relaunch the iFlash application
2. Click through the next buttons and get to the screen that has Read ECU Memory and Program ECU Memory.
3. On the right side of that screen you will see a button that says Diagnostics, Click This.
4. On the bottom of that Diagnostics window, click on Throttle Adaptation.  It will run through the process.
5. Once it has finished, click on Read Trouble Codes.
6. Then click on Clear Trouble Codes.
7. If no codes are present, you are done.
8. You can now turn the car off and start it which it should operate normal.
9. If the idle is still a issue, try to do it manually as below with step 9 to 13.
10. Remove the key from the ignition
11. Reinsert the key and turn the ignition on to position 2 for 60 seconds (do not touch the throttle).
12. Turn the key off for 10 sec (do not touch the throttle)
13. The throttle is now readapted and vehicle can be started and operated as normal
14. You can also do this with a Durametric tool.  Read Here.
