To me it seems like there is some differences between the Speeduino wiki and Tuner studio.
Speeduino Wiki:
Wasted COP - This is a convenience mode that uses the same timing as the 'Wasted Spark' option, however each pulse is sent to 2 ignition outputs rather than one. These are paired IGN1/IGN3 and IGN2/IGN4 (ie When IGN1 is high, IGN3 will also be high). As this is still a wasted spark timing mode, only crank position is required and there will be 1 pulse per pair, per crank revolution. This mode can be useful in cases where there are 4 individual coils, but running full sequential is either not desired or not possible (Eg when no cam reference is available).
Tuner Studio:
Wasted COP: Ignition pulses are output on all ignition channels up to the number of cylinders. Eg 4 cylinder outputs on all ignition channels. Note that your board needs to have same number of igntion outputs as cylinders to be able to run this
As I understand it, Tuner Studio uses 4 ignition outputs and each output fires once every 360 crank rotation.
Speeduino uses only 2 ignition outputs.
Both on a 4 cilinder engine.
On a 4 cilinder it doesn't matter that much.
But then on a 3 cilinder (3x120) you need to go sequential ?
