Hello and welcome to the forum, thank you for the post.

Regarding Raster formation (Stacking) you can utilize each channel for each ignition event (Up to 4 with a 4 channel scope)

They will however be displayed only when each ignition event occurs (in order of time)

For example use a rising edge trigger on channel A for the ignition event from Cylinder 1 and connect cylinder 3 to channel B, cylinder 4 to channel C and cylinder 2 to channel D. (4 cylinder engine with firing order 1342)

Select a time fame of around 20 ms/div where you will see all ignition events taking place in order on one screen at idle speed

For Parade formation you would need to purchase the Mixmaster which is of real benefit for engines exceeding 4 cylinders

The post below may help with a description of how the Mixmaster is applied to the vehicle
