i am interested in efi332
i have been interested in injectin a bike for a long time
my electronics is only as much as what i picked up while doing
electro-mag and semiconductor physics
so i am interested in ready made efi
so if anyone could point me at any ecu's suitable i would  be gratful

has

need.

>Another suggestion would be to start from the ground up.  There is an

>control the fuel injection (and ignition for that matter) for your bike.
>Here on this list in the past few weeks someone posted that they had
created
>a hardware-based EFI system that might be a good starting point as well.

>I don't mean to dissuade you from your quest ... I've actually got an

provide.
