You are receiving 37 PIDs/s which results in an overall update rate of 10 Hz. This is actually a good value - you can't achieve a lot more with an ELM based Bluetooth Low Energy sensors (available bandwidth). You can optimize results by switching from ALL control units to just ECM/PCM. Enter "PCM" into the respective Expert Settings field.

This are simply to common abbreviations for the main engine control unit. Both have the same effect independent from car or configuration.
