PID polls are requiring 125ms +/- 5ms each poll and really making for a clunky routine when fetching one after another. ISO 9141 on 1998 Toyota. Can anything be done to fetch multiple variables in one poll? stampTime = millis(); obd.readPID(PID_THROTTLE, throttle); throttleTime = millis() - stampTim...

It's in spec, but I've read too many instances where it caused probs and a 5v buck converter fixed it. I like the sound of your option #1.... you said ...

Looks like a very cool product, thanks Spencer for offering it. i will be using it to read coolant temps and control dual fans as well as display temps. specs show that it draws 5mA which is acceptable for parasitic draw on battery when parked. I'd like to limit ...
