I recently purchased an OBDII scanner that allows me to read and log data using my tablet.
How do I get the most out of this device?
I am already familiar with simply reading the trouble codes to learn about problems. I know that having a trouble code plus additional data points can help me quickly triage a problem.
For example a vague emissions code could be something as simple as a vacuum leak or as rough as a bad catalytic converter. Can an advanced device that logs values help triage broad trouble codes through records of other data and details?
What data points should I just log by default to capture the most problems? Should I be capturing everything?
