When to ignore OBD Data

I have an OBD reader connected to my car. The reader lost its mind and stopped communicating with ABRP or Car Scanner. (That part isn’t the issue).

This caused a very difficult situation with ABRP because it kept using the last reading it got from the reader to do its calculations. Since that data was wrong and not changing the routes ABRP were doing were basically useless.

Eventually I realized it was using OBD data, so I tried unlinking the OBD, but that didn’t help. It still used the old data.

I fixed the problem by updating the firmware on the OBD device and then relinking it back into ABRP.

I have two suggestions:

1) Don’t use OBD data that is “too old”. I don’t know how frequently ABRP pulls from the OBD, but I’d think if it has been more than 3x that time it is probably time to ignore the previous OBD data.

2) If the user unlinks the OBD device, clear the OBD data.

Thanks
