I'm working on building an ECU with a fellow from the Speedtalk forum. It's a project he's been working on for awhile and then it stalled. He sent me a board and I'm trying to fix up the code while also drawing schematics for the board I would like to build and sell. The project is starting with an evaluation board from Freescale for an MPC 5634 processor. These boards are $99 and seem to be capable of doing the required work with a little help from another board with jumper cables.
We have Tuner Studio running with this board now and I hope to get it to run an engine very soon. I was originally going carb on my motor so it's going to take a little while to convert it to injection. I have some ideas on how and where to proceed but I would very much like to hear the opinions here.
So opinions on what parts and how to setup my Ford 302 for injection and what would you find useful in an ECU for your own builds. This is still a clean slate. It's not realistic to support everything, so rather I would like to find a subset that will make a quality ECU installation. I see aftermarket stuff going for $2000 and up and it seems very steep. The electronics are not expensive anymore but it seems the prices have not come down to match.
Here's a picture of the current board.. It is mostly covered with jumpers, switches and lights, the actual unit could maybe be smaller.
Interesting stuff, I have used the Emerald cams ECU on a 302
http://www.emeraldm3d.com/ . The guys there are really helpful and will tailor make one for you for around £500. The last one I bought was to make a 302 sequential injection and wasted spark ( junked the dizzy) . Hardware is about like this
