If you are looking for a sensor for an aftermarket ECU the turbo dizzy can run a dual track optical disk in it (does anyhow) but you can run a modified disc like diyautotune, etc makes to give you TDC and RPM info if you wanted to run a distributorless ignition, sequential fuel, etc...
I’m running one in my engine but only using it to run wasted spark and batch firing of injectors
