The dash interface is the big issue. I don't know how they get around that.

The earlier dash is easy; the atari dash still uses conventional signals. The ABS is a purely stand-alone system, as is the climate control.

The later style, with the CCM is the problem. The CCM needs engine data (vehicle speed from the VSS is #1). Without that, you lose ABS/ASR...

That part is easy. 4k PPM signal. Most of the fbody guys use a dakota digital converter.

I still haven't figured out the way to fix this... unless the CCM can be tapped into the VSS to satisfy its need.

Otherwise, the CCM handles VATS and that's about it.

The page still populates for the LTCC stuff... donno if that means anything, tho.

4k PPM from the dakota box into the CCM/BCM.

In theory, the CCM will master the aldl comm too. If the ECM is 'missing' it might trip a sys light, in which case I'd pull the bulb.

Everything else on the cluster is a "normal input".. The odometer is the only issue with the late style dashes, and the reason I abandoned my dash swap. S10wildside - a thirdgen.org member owns EFI connection (Brian's first link).. These guys have been working on some pretty neat stuff. I'd switch to an LS1 ECM if it didn't have a 750cfm read limit.
