Fiat - Subaru trigger signals

 

Fiat Coupè 1.8 16V, 130 HP (in origin)
1747 cc. 16V DOHC, variable intake cam timing, naturally aspirated
I have mounted an Eaton supercharger, so it is charged now
Original ECU is an Hitachi MFI-018 sequential injection and ignition, 4 coil on plug

The trigger signals of this Fiat engine is very similar to that of Subaru 6-7 engine.
Crank signal is identical! So, I must trouble only to modify Fiat cam signal, to make it as the Subaru one, because Subaru is a well known engine and many stand-alone ECUs can manage it.

Now some pics, compared with those of the Subaru 6-7 engine
