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.

Nice job Paul,

I made one for mine out of rhino plastic, my keyboard is one of the flexible roll up types
and a 8in touch screen.

I since I have also purchased the micromite and the LCD screen for it to make a EFIS
and another maximite for my EFI and EI controller.

They are pretty neat and work great.

Mike do you care to share some of that source?

I am glad to see there is at least one other person with vision out there :-)

I thought a lot about this and there were very few people out there
with vision. The Wright brothers had it and so did Kenichi Yamato
with the Mazda rotary.

Dave Garber, Abel Ibarra and Russ MacFarland on the TTC project.
Lou Ross on the Ford based gearbox. Reginald Joseph Mitchell for
a life devoted to fast airplanes like the  Schneider Cup racers and
the Spitfire. Charles Lindberg for seeing the possibility of flying
long distances.

It takes vision to see the possibilities and perseverance to see it through..

These are the achievers.

Not something one can learn in school.
