roughly one or two updates per second at 9600kbps?

Each update is 504 + 261 bytes.

Overall data rate is a combination of rusEFI and frontend software. Depending on what gauges you have opened or what fields you log data rate would be different.

One day someone should start data rate investigation by looking into the logs and checking what ranges of the overall output each specific software is requesting. And yes, as Dron say - we do not support (faster?) stream protocol at the moment.

This can increase data refresh rate over slow interfaces.
I'm going to look at this someday.

I have a regular HC05 module connected to the UART port. BT module has been configured with baud rate=115200.
Current data rate logged in TS is no higher than 5 reads/sec. With MS3 and the exact same module I get close to 30 reads/sec.

Is the low data rate due to the fact that the telemetry stream include a large quantity of variables? Floats vs. int?

Is there a way to improve the data rate for consumers wanting to run a digital dash with their phones or tablets?
Would it be possible to increase refresh rate if there was a way to define which variables are being sent over UART?
