My Waggy has been fuel injected (Megasquirt) for some time now and I've been happy with everything save for timing/spark control but I always knew I would go distributorless at some point - and that time has come. I *may* have also needed to do some cleaning/painting while in was in there.
As always a big thanks to my partner in crime Ryan for working through this madness with me
With a DIS setup, we need coil packs, wires, a crank pickup, and some sort of toothed wheel to read crank position. With the AMC engine, we also need a way to drive the oil pump once we pull the distributor.
The starting point
First up, pull and gut the distributor.
Cut down the shaft and housing, inserted a bushing at the new top then welded on a collar to the top of the shaft. The collar allows you to be able to turn the gear by hand for alignment to drop in.
Used 3D Printer and TPU to make a cover for the new distributor stub
We messed with a few options for a trigger wheels, but ultimately decided to make our own via drilling shallow holes in the damper in a 12-1 pattern for the pickup. Back to the 3D printer for a drill template since this has to be precise and maintain balance.
Next up is the crank pickup, used a Ford 2.5l 4cyl crank pickup, mounted to the fuel pump block-off plate.
And a mount for the coils
Wiring harness for the coils
And where it stands this morning.
Next steps are a bunch of wiring, testing, Megasquirt changes, and probably more - probably going Contour fans and using MS to control that as well.
