Jag V12 ECU Mods

If the Jag engine you have, fires two cylinders at a time, then you can use
an ecm for a six cylinder engine, by running the injectors in parallel for
the two cyls that fire simultaniously.  If your engine fires one cylinder
at a time, like most American engines, then you need to research and
identify an aftermarket ECM that will be suitable.

its my understanding that Electromotive as well as Haltach supports more
than eight cylinders.
