M29 re - power questions in Headquarters Posted July 27, 2020 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.
