Some people are reporting an OBD data error when using the PLX cable and Harry’s laptimer. Mostly it seems to be with 996/997 Porsches but it could affect other cars as well.

If you’re getting the following error: “The OBD sensor does not receive data at an expected rate. Please check compatibility between car, OBD dongle, and LapTimer.” Harry offered the following workaround:

Please add the following string to LapTimer ‣ Administration ‣ Settings ‣ Expert Settings ‣ OBD Tweaks / Exclude PIDs:

Code:
0900092009400902

With 0902 disabled (because it is not available anyway), LapTimer will not be able to receive the vehicle identification number and consequently will not switch to this car automatically. This is usually not an issue, just make sure you select your 911 manually once (e.g. in Timer ‣ Status).

You can test it on the street.  Let us know if you had the problem and if this fixed it, thanks.
