I am thinking of using a Megasquirt myself.
Please let me know what you come up with.
I have the PC board and the CPU.
I am also interested in the Ford EDIS ign system.
I can have a wheel cut with a plasma cutter.

I finished putting mine together yesterday evening. I also have the
Megaview and the Stimulator. Hooked up everything, and it all works
perfectly. Woohoo!!
Looking at your pictures:
- The blue board is the Megasquirt board, and I recognize the
smallest board as the Stimulator. But what is the larger green board?
-You probably just stuck it in there out of convenience, but the MAP
sensor goes on the bottom of the board in the opposite corner. It's
U2. Bend the leads so that you can read the writting, the port faces
out toward the board past the connector.
-Having built several electronics kits, and building up a project
from components I ordered piecemeal, I would HIGHLY recommend that
you get one of the Megasquirt kits from a vendor the website refers
you to. It is not much more money than what you would pay buying the
components yourself, but the organization and completeness of the kit
is simply amazing. Once you consider items that you would have to
buy minimum quantities of to get one or two pieces, it's probably
cheaper to get the kit. It comes with a very nice, well engineered
case (I got the black anodized case...beautiful). Things that you
need small quantities of, like double-sided heatsink tape, are
included, as are things that would be tedious to make, like the
aluminum bar heatsink. Even a short piece of properly sized wire to
make jumpers with is included. The connector to make the wiring
harness is in the box. All the components of one value are packaged
in a tiny ziplock bags that are labeled with the value, component
designation (R47, C13, etc), and any special instruction (mount with
1/8" spacing, insure proper orientation, etc). I started assembling
it last Tuesday or Wednesday, and finished it last night. About 8
hours in total. I was very meticulous about double checking all
component values, which slowed me down, but I didn't have to do any
rework to the board. This would NOT have been the case if I tried to
build the part up from pieces. I'm not saying you can't build the
part piecemeal, but I've never worked on a kit that was as expertly
put together as this one. If you have a fully stocked electronics
shop to pull from that is very convenient I might consider just
getting a blank board, but otherwise not getting the full kit just
doesn't make sense.
-I will have to order an additional MAP sensor for automatic mixture
correction.
-I may have to order an additional VR sensor processor. I've built
the board to use the Hall sensor/optical input to drive the
tachometer with input from the EDIS module, but some of the
instructions I've read seem to indicate that the Megasquirt-II code
would process the dual-VR sensors directly. This will require me to
do some investigation, but modifying the board will be easy enough.
I need:
two EDIS-4 Ignition Modules
two VR sensors
one 36-1 tooth ring
one GM temperature sensor.
-I'm ordering the EDIS components from BoostEngineering. Below is
the email I got from them this morning:
Hi Ernest,
Price for parts is $139 and shipping will be $20 for a total of $159.
Parts are in stock for immediate shipment.
I accept payment at: boostengineering@earthlink.net
Thanks,
Brian
