[Gmecm] DIS 4 cylinder hac?

[Ryan Hess]

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...

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.
