darn - someone tell me how to load photos on here, please. At any rate I finished the installation of my Megajolt set-up. Parts consisted of a UK-sourced trigger wheel with hub and crank bolt, sensor and sensor mount (about $250 - more on these later). From a local junkyard I got the EDIS spark unit and coil pack from a '95 Ford Escort, plus wiring harness connectors. And From Autosport Labs I bought the Megajolt V4 control unit. Plug wires came from Advance Auto, also Escort type (Bosch premium).
As it turns out, the sensor mount kit was for an A+ Mini, so I had to do some modifications to it, fabricating bits of aluminum to get the sensor out where it needs to be, modifying the hub, and sectioning the steering rack mount about 1/3" to get clearance. That was the major part of the work. I installed the EDIS unit and the coil pack in the engine bay, and the Megajolt controller in the cockpit; it uses manifold vaccum to sense engine load, so I tapped my Titan manifold appropriately. Wiring was straight-forward, except you have to use shielded cable for the wires from the sensor to the EDIS and the PIP and SAW lines from the Megajolt to the EDIS, with the shielding then grounded. Hooked it all up and used an advance curve from a 123 distributor found on the net as a baseline - and fired it up. It was a strong runner before (1312 cc, 266 cam, 1.5:1 rockers, HIF 44, LCB header, Pierce head) but now has even more grunt. Next stop: chassis dyno.
