Syvex is a Motec style ECU without the tech support but with sadly a few gremlins. One UK rider went from going 7.30's with Motec to nearly flipping his bike with the Syvex boost control breaking his wrists in the process. That's with the Syvex tech guys directly tuning his bike. That was after a year of hunting down ghost shift kill signals on his launch.
Stick to the proven path on bespoke ECU's.
Jack's, very similar a motorcycle, it seems to me it is.
