Ah, the Runtime error issue. I like the sine wave out puts. Ford in 1981 used simple digital to analouge outputs to control air fuel and detect piezo electric knock and perform multiple Do if True commands. So did Chrysler Corp with Electronic Lean Burn. And GM with its AC Delco feedback carb. Michael Angelo from Richard Holdeners Cadillac 500 QuadraJet performance dyno tune discussed how the Chevrolet Qjet used administrative responces from the Delco P4 to control PWD to trim the air fuel ratio. He felt your kind of Arduino system might work better. See ruclips.net/video/9sAscBa1-qo/видео.html I think your Z80 might be able to duplicate a Throttle Position Sensor O2 sensor Manifold Air sensor closed loop ir fuel ratio trim.Knock sensor ignition advance control from a square wave form and a total advance strain gauge transducer. Its a nice system you have. 1979 to 1985 was a fun time for control systems and there is still a place for it today to replace or augunent proprietry systems in old cars.
I'll bet if you added a simple RC low pass filter, you'd get a nearly perfect sine wave.
You're right of course. I did that a while ago but haven't made a video about it.
