Not doing ANY computers or electronics at all. Solenoid will be the highest tech electric on this machine.
Would actually be happy if I could hand start . I do not consider electronic ignition electric fuel pumps and electronic fuel injection to be upgrades. Rather all are things to be avoided at any cost.
I am aware that diesels do not produce a usable vacuum signal ( they don't have throttle plates so the I take is basically always at ambient unless they are turbo'd)
Many many diesel autos are automatics ...there fore there must be rpm or other controls employed.
