When asking ecm questions

[Frederic Breitwieser]

> 1.) is the DIS remotely compatable, or use the Buick?

If you want to use the FWD Buick computer, I'd use the FWD Buick DIS box
just to ensure compatibility.  It does spark nicely, up to about 5200
RPM then the spark power drops off quite sadly.  Big improvement over
bone-stock HEI.  I removed the rev limiter in mine via editing the
eeprom.

> 2.) Can the code be modified for the ignition pickup (in degrees) as the
> 2.8L pickup is in the block (not on the balancer like the GN)

I have no idea quite honestly... I used the FWD timing cover with the
sensors, on the FWD block, then eventually the RWD block.  ALmost a
straight bolt-on.

> 3.) Would the 2.8L flow enough air through the MAF for idle.

I don't see why not... you might have to turn the RPMs up slightly...
but of course, I haven't tested this myself.

> 4.) Would one use the 2.8L knock sensor with say an '86 knock module, as
> the knock circuit is integrated in the newer (style) ecm.

I would use the knock circuit in the ECM.  Everyone, feel free to
correct my advice.

> Any thoughts?  (I know use a Buick, but I was thinking Z24, here)

That's okay, nothing wrong with mixing and matching.  I'm building
another 400+cid V8 mopar with GM EFI.  Hey, whatever works, right?
