My setup: Holley HP on 4 cylinder motorcycle 12-1 crank wheel and no cam sync (35 year old engine design). Firing order is 1-2-4-3. Reading “Fuel Injector Information - Strategy” in the Help guide. Can I assume the descriptions given are specific to 8 cylinder engines? And for a 4 cylinder engine I would double the crankshaft degrees listed? For a 4 cylinder:
Bank to Bank - Would fire half the injectors and then the other half every 360° (1 & 4 inject at 0° and 540°, 2 & 3 inject at 360° & 720°.)
Untimed Sequential - Would fire each injector every 180° (1 injects at 0°, 2 injects at 180°, 4 at 540°, and 3 at 720° **OR** 4 at 0°, 3 at 180, 1 at 540° and 2 at 720° — just depends on where the cam is the first time the crankshaft comes around?)
Paired - Would fire a pair of cylinders every 180° (1 & 4 inject at 0° & 360° and 2 & 3 inject at 180° & 540°)
To run paired, I have to wire the injectors in pairs? Injector 1 output to both cylinders 1 & 4 and injector 2 output to cylinders 2 & 3? (And leave injector outputs 3 & 4 unconnected.)
Thanks! All the other questions I’ve had, have been covered in the forum, just a little confused on this one (mostly caused by my experience with other ECUs we’ve used on the bike prior).
