Can anyone define IDC by crankshaft/camshaft positioning? i.e. is 100% duty cycle only in relation to the intake stroke, or does it include the exhaust stroke also?

General question-no Mopar cars involved. Just would like to know what my scanner is telling me. If car is at 100% duty cycle, does it spray thru just the intake, or during both strokes?

Be thankful you guys have Mopars- probably better fuel mgmt. On some Gov't Motors cars, opening up the intake and exhaust will lead to 100% duty cycle 'cause they're fuel mgmt. is already on the hairy edge.

Apparently duty cycle is a percentage of 1 complete power cycle (2 crank rotations). I know what my cam duration is and I don't want to create a CIS system. Matching injectors and fuel pump to get duty cycle I can live with.
