Grassroots Motorsports Magazine had an article about open source Mega Squirt
in the Oct 2005 issue Page 89.

It is far more highly developed than I thought.
It is low cost and has some real nice features like data logging.
It is not for everybody. You should at least have some electronic
tech expierence. PL

Ahhhh ... I see someone else here *actually looked at* the MegaSquirt
links I posted over the last year.  Good.

I think this is a GREAT fuel injection system.  Open source is the way
to go (not unlike our rotary engine work here - the sharing of ideas).

HOWEVER ...

As I stated before, I wouldn't necessarily *FLY* with the board yet -
I'd have to get *REAL* comfortable with it first.  I'd want a version
that has two boards for redundancy, at a minimum.

ESD damage would be a big concern for me - one static spark = dead
electronics.  Dead electronics = no fuel injection = unplanned landing.
ESD needs to be carefully planned for and protected against - in any
aircraft electronics.  ESPECIALLY powerplant controls.

Tracy has a redundant, proven EFI system for a *very* reasonable price.
I'll probably use his system - certainly when starting out.

That being said ... MegaSquirt is really cool!  Go check it out!

No I have looked at it Vince on and off for the past three years.
In fact I uploaded the schematic a couple of years ago.
Just to prove it here it is again. The file date is 05/05/03 :)
It is cheap enough you could put two in there and a relay
like Tracy does.
