Sometimes you don't have 4 outputs! Not everyone uses DTA or their like! I have a Motec M8 (ancient - yes I know) it has 4 Ign outputs but to run wasted it requires 2 outputs split to run 4 coils via an ign. amp! The Internal amp's cannot drive external coils directly so to run at all, whether wasted or sequential, a Bosch or similar ignition amp is required. It doesn't have the software sophistication to be told to internally pair 1&4 / 2&3 !

I don't think any Motec's had internal amps to run conventional coils ? And If they dont have enough outputs, it's a different scenario entirely.
