[Gmecm] DIS 4 cylinder hac?

[davesnothereman at netscape.net]

Any value lower than stock would "work."  Why not negate the V8 
distributor values?

   I'm trying to figure out what values would work with a DIS V8... If 
there's practically no difference between the I4 and V6, I wonder if I 
should just use the stock V6 values of -10 and -70. That's pretty close 
to the values I'm using now anyways..

Maybe no surprise that the limits are similar to V6 DIS? The numbers
are based on the type of ignition system. Distributor type 6 cyl is
lower, and 8 is lower still.

 Thanks for the info, that's VERY intriguing. The quad 4 uses 0 and
-70 for min and max, and the 2.2 uses -65.8 and -6 as the min and max
respectively? I wonder if in the 2.2 code the min/max are switched
and/or handled backwards?

 What's most intriguing is both these values are almost identical to
the DIS V6 min and max values...

found.

1989 quad 4 engine, 7749 ecm
Ref angle = $AB
Min angle = $0000
Max angle = $FF39

1992 S10 2.2, 16168505 PCM
This one uses min spark a little differently:
Ref angle = $BC
Max angle = $FFEF
Min angle = $FF68
Min angle in DFCO = $FF44
Min angle during torque management fuel cut = $FF44

 Would you be so kind as to post the "Min/max spark retard" values (or
whatever they chose to call them)? Then again, I somehow doubt they
even included them in the definition........ their files are largely
incomplete like that.
