Hi Paul!

I believe you are scheduled to speak at Whiteman Airport this month. I will
try to bring my firewall backward setup from my cozy4 as a display. I should
easily have the tube frame built and set up on an engine stand. I need one
of your Rhino drawings to start the tube frame. I can also bring a
dismantled rx7 engine to put on the table, and should have some soldered
aluminum tube p ports ready to show. I will be purchasing a reduction unit,
and bell housing soon, and may have it there as well.

I plan on using megasquirt to start with, for the ignition/injection stuff,
and am going to purchase one or more of the atmel boards to see what I can
do with that. I also plan on using a motorcycle stator/alternator setup for
ignition backup.

Can you recommend a pc based oscilloscope? usb style maybe?

Maybe we can talk Dave Leonard into flying his RV6 up.
Or Steve Thomas Glasair from Santa Barbara.
Randy's one rotor Dragon Fly and Mike's RV4 are not quite ready to fly.

I don't have any direct experience with PC based oscilloscope.
However for our purposes this device will do everything
we need done for way less money. Less than $100.
It will give you valuable feed back data on your EFI in the
bargain. It will tell you what happens when and how much.

You will need to add some $10 pressure sensors if you
are looking at manifold pressure or air speed. It is also
a good idea to use $1 opto isolators if you are looking for digital
events such as ignition coil and injector triggers.

I have successfully used this one but there are several others on the market
for about the same amount of money. Search Data Acquisition.
