Wireless racing telemetry and lap times

Hello all!

I recently got involved in lawn mower racing and now we have a team building a race machine for a 12-hour endurance event in february.

I thought it would be awesome to have some live telemetry data from the mower sent to pits during the race. The usual throttle, brakes, steering, rpm, oil temp, acceleration, GPS and whatnot. From reading these forums and googling I got pretty good picture for what I need. Just would like to know if the Uno I have is good enough or are there better suited boards for this. The receiving end is a Nano connected to a laptop and the other wireless module.
The wireless part would be handled with NRF24L01+PA+LNA wireless modules, which should have range of 1100 meters. Plenty for me.

That was the easy part with plenty of instructions available. But…
I would like to be able to also send data to the vehicle. Mainly lap times to be displayed for the driver. Could I tap into the MyLaps system and read data straight from there or get it from Race Monitor and have a script to process it and send onboard? Even manually typing it and sending the data would do. Can just two boards handle this or should I have one more for the onboard display?

The nRF24 is a transceiver - a pair of them can send data in both directions.

I have no idea whether you can " tap into the MyLaps system" mainly because I have no idea what it is.

That's probably assuming good antennas and clear line of sight. Do test at the actual location to see if it really does the job for you.
