It's well known (visit the site at "Binder planet" guys over there have been using the GM computers with removable chips to create scratch built DIY EFI systems. But the guys, say, doing Magnum and hemi swaps always seem to end up sending the box "to somebody" and pay to reflash the thing.
Plus, "Ma" Chrysler won't release any data on the things. I guess I can understand why
With my backyard nonsense, I ended up first with a Holley Commander 950, and now, a Holley HP. they ain't cheap
