There's at least 2 piggyback or replacement ECU systems using the factory harness for the 3.2 with Motronic. If you'd bought an EFI car, that would've made it easier...
Plenty have added injector blocks/fuel rails, sensors and a toothed crank pulley to convert CIS to EFI. But no piggyback, as there's nothing to piggyback onto.
I do seem to remember conventional wisdom being that SC/3.2 cams are about as far as you can go with CIS - too much reversion for good manners with anything wilder, you'd need carbs or EFI.
For a street car, I'd trade low/mid range pickup from the lower torque of SC cams against a few extra ponies at red-line. You'll get the advantage of one a lot more than the other.
