Step 3: analog track testing. 
We used an analog throttle in the club plug point and held it open on full throttle.
We then powered the SCP by a 9v battery to drive the car.
Note: Depending on the club/track controller plug system a good tip is to modify your own plug and hard wire the connection between power supply + and track +
If the track voltage does not exceed 12v you could even use the plug to power up your SCP

Step 4. : How To ? 
We have not worked out how we can test:
- the emitter LEDs for lane changing (incorrectly polarity stops it working) 
During assembly: Almost all LED's have a polarity mark, when in doubt for the IR LED, do a quick test on the lead wires with a normal LED with visible light.
LC Failure check: Place car on XLC track, move the car over the LC sensor with one of the LC change buttons pressed, repeat process with other LC button pressed.
Repeat procedure on other lane.

- the hall effect sensor for lap counting. (Installed upside down stops it working)
O2 system has a fail safe feature that prevents cars stopping on top of a finish/pitlane magnet. 
If the hall sensor detects a magnet and brake is applied it will send a short power pulse to the motor to move the hall sensor past the magnet.

This feature can also be used as a simple stand alone test of the (mounted) hall sensor with an external magnet:
Power the car and SCP, take an external magnet and hold in under the hal sensor, if mounted correctly wheels should be given a short spin.
If it doesn't work the first time, flip the magnet and repeat. 
If it doesn't work the second time, flip the hall sensor and repeat test.

- set up an oxigen dongle to update firmware on the chip and SCP. 
To do so you would need the download the Slot.it boot loader program and install on your PC. 
As O2 RMS and Bootloader software is windows only and I don't run Windows...no experience  
Check Slot.it info on its new app based Chip update firmware.

Hope this helps

with kind regards
