Front cover for Peugeot sensors

I must have drawn this a few times already, but I hope I am getting close now, but the real candidate will surface when I do the trigger wheel tests.
The Peugeot sensors are shorter, so allow for better EFI triggers to be used (more depth), but they are taller out of the cover than the BMW sensors. They also have to be recessed into the timing cover, so that they will clear the fan, although there is a plan for this later on the big bore engine.
Here is the wasted spark single tooth variant, or a twin spark and EFI capable version, assuming you are using a toothed wheel and suitable ignition controller, which only needs a single sensor.
The second sensor slot isn’t drilled all the way through, but all the critical machining is done to enable twin spark with the planned ignition controller.
This means you can start with wasted spark, and upgrade to twin spark later, or change to a different ignition controller, use a toothed wheel, and do twin spark & EFI, just like a modern car. For example, this type of toothed wheel will run MS Extra, B&G code on the MegaSquirts & MicroSquirts, plus all the usual suspects DTA, Omex, Emerald and Lumenition, in a sequential or wasted spark mode.
