Jamie,
Here are the 95 993 ignition and fuel maps. The theory that twin plug needs less advance is sort of out the window if you look at the 993 Ign maps. In the PT Ign Map it does seem to back off on ignition for part load as compared to the 86 Euro. But the 993 WOT Ign map pushes into the 30BTDC and one wild spot is at 2480RPMs it pushes 67BTDC! I keep looking at it saying it must be wrong, but it appears to be by design. Any idea why push so much advance at WOT 2500RPMs?
EDIT - EDIT - EDIT - do not trust these maps! they are likely not correct!
