My hall effect signal has been slowly deterioriating. I am using this as an opportunity to bring the ignition timing under control of the ECU. In doing this I will be replacing the 1984 distributor, which featured centrifugal and vacuum advance with a 1986 distributor which has neither advance mechanism because these features were moved to the ECU for that model originally.
Basically, I'm following in VW's 1980's footsteps. Below is a fun video of me testing that the programmed timing is going to fire when the rotor will be pointing at a plug wire.
