Just a quick update with my neutral width issues.
Re-calibrated the speedo and updated the software to 212, but it still has a very wide neutral area compared to my RS Pro. (Turned to min)
Also tried the min throttle by adding a bit more, but still there.
The car has also started to stop randomly during a race, normally within the first minute of racing, then will run fine again.
Have checked battery terminals, motor and speedo heat and all fine... weird..
