Today John Lee sent me a nice link to a scooter hacking forum. The short of it is I got a nice hint to how the data structure is built. The last  byte of the data packet is CRC-8 Maxim. So to alter any packet to test other configs on the scooter you have to calculate the CRC byte for the end.

Here are some test examples I made from the know packets that I have.

So I can now build a CRC calculation function and create new packets to test there different Hex numbers and there functions.
