I set out this morning to build a lap top Maximite.
There are lots of jobs a Maximite can do. Literally hundreds.
Not just EFI and EFIS. Auto pilot any one?

Another job is measure the compression of a rotary engine
10 times a second so one gets a nice pressure curve.
If you buy this tool from Mazda it is $300 or more.
This is used to detect leaking rotor seals both apex
and side seals.

Interfacing it  to  two automobile racing weight scales gives a
low cost aircraft engine dyno as the Maximite can read
the wheel weights  at high speed and average the readings.
The torque  and RPM give the net HP out of the prop.

Another job is get pressure wave shapes out of the intake
manifold to make sure your engine is tunned properly.

The idea here is change the runner lengths until the torque
peak matches the prop torque requirements.
Best done with a ground adjustable prop pitch.

So I decided to put the Maximite  in a steel box and mount it
under the Gear Head keyboard. The box is made from
air conditioner 24 gage sheet galvanized steel. Cheap, easy to cut
and bend with no bend allowances because it is so thin.
It is also readily available everywhere.

Here are some pictures. Pretty much all self explanatory.

Ask away.

I may build these Maximite boxes for sale.
Let me know if you are interested.
