This is a 2" by 6" aluminium extrusion about 4 inches long. This is
very similar to what I am doing with the ignition stuff so I am all
set up to machine the covers.

There is an aux board the same size as the MM board mounted below the
MM.

So far there are two VR sensor circuits and eight high current
drivers for four coils and four injectors on the aux board. The next
thing on the aux board will be two manifold pressure sensors. One for
the front rotor and one for the rear.

The back panel has the connectors for the VGA, the PC keyboard, the
USB connector and the 12 VOLT power connector.

The front panel will have two DB15's one for output and one for
input. Also a slot for the 65 gig SD card.

So far all through hole.
-----------------------------------------------------

Here is my latest iteration of the PC board. I added an RS232 9 pin
D-sub-min. Matt Boiteau is using that.

The surface mount manifold pressure sensors are on the right, 29 psi
so this board will work with turbo's. I am thinking of adding  EGT
sensor circuits.

EGT sensors respond slowly so It mind be possible adjust the mixture
in cruise.

Of course they could be displayed on the EFIS part.

Anybody have any other things they would like added?

I should have this running on the RV4 in a few weeks.

What about using a USB port possibly to use a flash drive instead of a SD
chip?

The Maximite comes with both.
