Future Features

Like all good gearheads, I have to have a list both of what needs doing, as well as what I want to do 'some day.' In that sense it is just like owning a house.

For my house, I collect ideas in a 'design morgue': pictures, measurements, blah blah of what might be interesting to do some day. I can pull these out later and it takes a lot less to put the whole thing back in my mind.

With cars, its a little more complex, not only because many of the ideas require very careful measurement and engineering, but also because vendors come and go, business change hands, and products are in stock, out of stock or just plain disappeared in the sands of time.

So I'm going to write down a bunch of features that I hope to use in the future, and do so here where I can get back to them.

Megasquirt Fuel Injection. To do modern, crank-fired fuel injection (where the computer controls when to fire each spark plug, not a spinning distributor, with its advance curve determined by vacuum and weights, etc) you need a trigger wheel so the ECU knows what point of rotation the engine is at, like so:


In the above example, the trigger ring replaces a washer of the same thickness, but of only the diameter of the hub. Unfortunately, replacing this washer would rule out the use of Air Conditioning. Why? Because when the AC compressor is installed, the tiny pulley that drives it replaces this same washer. One or the other, or find a 'third way.'



The potential 'third way' is to machine reliefs into the surface of the flywheel on the crank side, and then install the Hall Effect sensor in the front case flange, either in the inspection port on the left side or on the factory timing sensor on the right. Viola! Instant trigger ring.



Or as long as we're operating in the realm of fantasy, where just writing it can make it possible, perhaps on the edge of the flywheel, just behind the starter teeth and mount the Hall Sensor in a drilled and tapped hole in the Transmission Bell Housing.


Any of these solutions can be yours if 'The Price is Right.'

Not to mention a MicroSquirt computer or Megasquirt brain to read the crank position trigger, plus injector control, Manifold Absolute Pressure (MAP), (Intake Air Temperature) IAT, (Idle Air Controller) IAC.

Air Conditioning: My darling spouse wants nothing to do with a vehicle that has no AC. Then again, she wants nothing to do with a TV without a steroid laced DVR (which I built her) so I suppose I am a victim of having been a good provider.

Apparently one call does it all. You provide the Bus and $2500, and they provide the AC. Sanden compressor as well as the evaporator and condenser. They do a good job. But THEY do it.
