> can you also get oil pressure, oil temp, coolant temp from the ecu ?

Unfortunately, oil only has a couple yes/no pressure switches, and they're
on their own separate warning circuit.You can add an oil temp sensor in
place of the drain plug, and hack in a dual-function gauge driving oil
pressure sensor with an extension tube and a hole cut in the left pushrod
tube shield. I did both myself. I can't imagine driving around without
knowing what my oil pressure was.

-might close at $80-90

That particular one is, unfortunately, a 24 volt model. But yeah, a 12V one
would just wire in. The hard part would be splicing into all the ECU inputs.

Yeah, there's not much to these. They're designed such that a relatively
bright heating/air conditioning tech can program them himself rather than
having to pay a hardware geek to whip something up in assembly language,
like the Bad Old Days.
As far as building a Better DigiTool, it sure looks a lot easier than my
idea: a hand-built PIC microcontroller based device, designed to be
programmed in assembly, or (if you can afford the compiler) in C. The big
drawback to that Millennium controller is that it's pretty big and chunky,
with a small screen. No real way to dash mount it. I'll probably still
entertain the pipe-dream of my home-made design...
