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.
Are you Paul Lamar? The email doesn't have much in the way of identification.
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'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
