I woke up with an idea.
No mass air flow sensor. No maximite required.
Use a potentiometer that is geared to the throttle with a small cog belts. Put 5 volts on top of the pot.

Or you can use a leaner pot with a slide throttle.

5 volts wide open zero volts closed.

Then use my one chip $1 555  EFI.

Super low cost super simple TLC 555 based electronic fuel injection.

You can use a low cost Harbor Freight Voltmeter to monitor the pot voltage.

There is no system EFI or carb that is lower cost.

Paul,

That is a throttle position sensor TPS

Why not put a pot in the cockpit at the rotation pivot of the throttle lever?

Paul,

Jst  a thought about eliminating the MAF.

Do we lose altitude compensation?

Joe Berki

Yes. But when you take off at a high altitude airport with a carb
equipped engine you must adjust the mixture anyway.

The mixture pot can increase or decrease the voltage applied
to the pot connected to the throttle and then the  555 at any throttle setting.

This is a quick, dirty and low cost  EFI way of getting your engine running.
You fine tune it with the mixture control just like you do any carb equipped
aircraft engine.
