[Efi332] list changes and appeal

[Green, Yakir]

How much cheaper will an EFI332 4 layer project be to buying a MegaSquirt system?

 

I have seen MS2 system for 400$ on e-bay ? anyone know where I can buy a cheaper one?

The efi332 page will not be closed of my accord. We'll just leave it open for reference.

No doubt. There are all the normal diy hurdles of implementing your own system plus
all the ones associated with programming, loading code, etc for the 332.

 

I have just sent Steve

Your contribution is generous, but that is not what the issue is in the referenced email. I was 
just stating that whatever is done with the list format, it is not likely to offend many
because the membership is small and generally inactive with this design.

Fire away with questions, I'd be glad to help. It sounds like your first obstacle is with
downloading software to the board(s). That solution depends on what PC environment you will
use. I know the windows solution well, but there are Linux solutions as well.
Once you get software loaded, communication is eased.

There are only 2 folks actively running efi332 units that I'm aware of. There may be more
but they aren't talking. So there's not much history to draw on for your particular combination.
The Sourceforge site for efi332 (http://sourceforge.net/projects/efi332) has working 
embedded source for the 4 layer board which can be made to work with the 2-layer. This suite
is set up for a V8 but is easily adaptable to any engine. There is also a console
program there to interact with the embedded code but since it is based on Labview,
you may want to do something different. I think Paul Helmuth has a windows based
console application that he developed that could probably be made to work.

And there is a second set of code on the efi332 site itself by Al Grippo , also set up for a V8.

 

The 2-layer design does have some inherent weaknesses so you may be better off investing your
effort with the 4-layer board. 

 

Seriously though, you have to weigh the merits of getting all this to work in light of
the hurdles. There are at least a couple of options that are easier to deal with, one of
which is Megasquirt which is close to turnkey by comparison. Not quite as capable as efi332
(yet) and perhaps less rewarding from an intellectual perspective, but a quicker and easier
path to getting up and running.
