Read evidence and context

Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

0 original-poster resolution reports. Counts can overlap; they are not unique people or a success rate.

0 discussions have direct query context; 0 report a fix in that context. Other evidence may inherit the discussion’s subject.

Suggestion

Probably not of much use ongoing, but interesting from a learning/understanding perspective.

Leading evidence: 'Use ongoing' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, The most frequently discussed action is 'Use ongoing' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.

Source reports, not a diagnosis or a success probability. Counts refer to discussions and can overlap.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

I just installed a Bluetooth OBDLink MX+ adapter (Porschetech3 said its best, good enough for me) and am asking for some basic advice. Besides using it to overlay basic driving parameters onto front facing videos, the included app allows for more sophisticated graphing of a multitude of engine sensor/performance parameters, including MAF rate, O2 sensor readings, long and short term fuel trim, etc, all labeled as either SAE PIDS or calculated PIDS. I am not a mechanic nor do i play one on TV, so what parameters would be of interest to graph. My car isn�t having any issues that I�m trying to diagnose but I�m trying to educate myself about engines and hope to use this tool to that end. Thanks.

POST 2Original post

I'm not sure if your OBD shows it, but I found it interesting to graph the throttle input vs. actual values. I tried this once with my durametric and it was neat to see how different they were in various scenarios. Probably not of much use ongoing, but interesting from a learning/understanding perspective.

POST 3 / ORIGINAL POSTEROriginal post

Still playing with available parameters. Went for a little 25 mile tri-oval jaunt this morning, watched MAF, O2 sensor readings and coolant temp, but this overlay is just speed:

POST 4Original post

I see some bursts in blue. Hope there were no men in blue to witness this.

POST 5 / ORIGINAL POSTEROriginal post

100+ a day keeps the mechanic away....i like blue!

POST 6 / ORIGINAL POSTEROriginal post

Dialed it down a little but more blue.....winning!
