Even with dual plugs per cylinder, you can't use the same coil to fire them. An EDIS coil drives 2 plugs which reach TDC at the same time. But the expectation is that one is a compression stroke needing a lot of spark energy, and the other is an exhaust stroke needing minimal energy. 2 plugs on the ...

The MJLJ-EDIS can operate engines with a 90, 120, or 180 degrees crank rotation between power strokes, or multiples of these. That doesn't usually work on a radial with an odd number of cylinders. If you don't have 2 cylinders reaching TDC at the same time, it would take twice as many coils. Bruce Roe

Engine
If its not a straight 4, what is the configuration? On my 2 cyl I used a V8 EDIS, because the 90 degree angle between cylinders was the same as a V8. Bruce Roe

POWER
Go to the OPERATION section, BATTERY CURRENT FOR EDIS April 2010. The EDIS uses electronic dwell control, so it only takes the current needed to charge the coil(s) each revolution. Current increases with rpm, of course. Much more efficient than a points system, that burns up extra power in a ballast...

Funky Diver recommends a good test, because it will find shorted turns or breaking down insulation that won't show up with an ohm meter. If a couple plugs don't spark, switch the EDIS coil driver wires. If the same plugs don't spark, its the coil. If different plugs, its the EDIS driver output. Bruc...

TPS to MAP
A MAP is better if your setup can use it. The engine torque is pretty much proportional to Manifold Absolute Pressure. But Throttle Position has a very poor relation to torque. First the restriction isn't a linear relation. Then, it only takes a little throttle for max torque at low rpm, but max thr...
