How to: Evo 8 ECU into 1G DSM

[danl]

A couple people have shown interest so I have decided to put this out there for general consumption. This is something that I had worked on over the winter and had done by early spring. I finally got around to plugging it in a couple weeks ago. The car starts up and runs beautifully. Dare I say that it runs better than an eprom 1g ECU. Those of you familiar with the Evo ECU development know full well why I decided to jump to this platform. I haven't worked out the ROM specifics yet but it looks like the EDM rom is the one you want to be running as it has less OBD2 checks and has less emissions devices to cause you trouble. It also won't throw the two CAS codes that the USDM rom will. Also a word of caution, and you will see the note in the schematic, buy a new Evo 8 knock sensor and use that in place of the 1g knock sensor. Other than that you can apply all the Evo ECU tricks, wire in a GM BCS, run any MAP sensor you like etc. You will have to run a 2g VSS (or maybe an evo) to take advantage of using the VSS for gear based boost control.

Please excuse my lack of internet skills. I have a link to a larger picture for the schematic below the small image.

EDIT:
You also need the proverbial first (actually second) start-up video.
