Coil Negative triggering for rusEFI
Posted: Wed Aug 31, 2022 5:09 pm
Been asked to deal with a couple of tricky classic car installs that need to keep the stock ignition systems and use the rusEFI unit in a fuel only mode triggered off the negative side of the ignition coil the way the old megasquirt units used to do it.
Current plan is to make a small module up replicating the optoisolator circuit that MS used to use.
Will probably find a small box to put them into and pot them in resin as they will have to live in the engine bay but will post up here with whatever design I work out for this as I am sure there are going to be some others with a similar need.
