What would it take to control a 6 cylinder 2 plugs per cylinder direct injected or port injected if had to be. Would prefer 12 cop coils but could use 6 duel output coils

Not a Speeduino.

[PSIG]

Speeduino (standard code, without modification) could run a 6-cylinder with paired port injectors and waste-spark coil packs or wasted-COP pairs (4 COPs firing on 2 cylinders each event). Board type could also be standard, e.g., v0.4 series or UA4C, etc.

Depending on the coil drivers used, a simple booster circuit may be necessary on the IGN outputs, but common IGBT types should work fine as-is. A small resistor (10 to 15-ohm 1/4W) should be added to each coil signal line when firing multiple coils directly from a single IGN output.
