Twin-Plug Ignition mapping?
Curious, how does a twin plug ignition map differ to a single plug map, in terms of degress of advance etc at idle/cruise/WOT?
The reason I ask is because when I install the piggy-back ECU on my Motronics & the 964 dizzy, I'd like to setup a basic base ignition map to get me going so I can get the car to a dyno tuner for more precise mapping.
Any input appreciated
