couldn't give a definitive answer tbh, the only way you will know is when you remove the current one and line up the nismo style one.
lights are easily changeable, thankfully
If key is remotely unlocking the car, it shouldn't need synching. Worth a try though.
Again, there is a How To in the Guides section. Try that.
two separate processes, it may open doors but the sync with the immobilizer is totally spearate
maf sensor or cam sensor could be causing the issue. A code reader may chuck some error codes that may help.
Also possible plugs need changing
thats my suggestions
I think with F1 the reason why some cases are reviewed after the race is that the stewards have far more information/sources available to them to investigate thoroughly than they do on MotoGP.
The think I found daft about the pit stops was they changed bikes. If you had an issue with the first bike, that would be cleared come pit stop. Why not make it more exciting and make the teams change the wheels.
