Just a little update. The Carrera protocol doesn’t like the bridge rectifier used for SSD compatibility. We can still proceed with Carrera based firmware work luckily by removing 3 of the 4 diodes. 
So it needs a hardware upgrade.
Not an issue as we held off on the current proposed hardware changes as we guessed Carrera might bring some issues to light as we progress into the nitty gritty.
Hardware changes:
We intend to add TX/RX (data out/in) for the proposed Scorpius/Carrera throttle receiver, these 4 additional solder pads will also serve our brushless motor, LCD gantry, and surround sound projects).
 The 3rd change is to change the power in wires to suit Carrera rather than the Scalextic wiring config, simply on the basis Carrera is much more popular.
The 4th change is a snap of board around 10mm by the width of the board 13.3mm that is soldered to any motor can that contains 3 simple capacitors to address back EMF spiking back into the car chip which can cause the chip to malfunction. 
The fifth Carrera related hardware change is to make the onboard Carrera track comms LED and the other one on a fly lead seperate logic and drivers so the spare LED can be used for any LED based purpose ie lights eg exhaust flame simulator or flashing roof lights.
We won’t start the hardware upgrades until we are more advanced with Carrera testing to maximise the window of opportunity in terms of recognising issues, like cars stuttering or taking off full speed or other issues. 
We have done some debugging and implemented the speed controller to car ID pairing which works well. 
The last stage of the car decoder project is to implement the safety car protocols which the team reversed engineered. Not an easy task as the old Carrera Manchester code is convoluted and extremely hard to work with compared to modern day coding. 
Once the safety car code is implemented the majority of the coding will be complete if not all complete. Of course a rigorous testing program will need to undertaken and chips sent to beta testers.
Hopefully we can start the chip hardware changes within a few weeks, which is a couple of days work, then add 6 weeks for manufacture and a week in transit.
Fingers crossed.
