Thoughts on injector pairing?

Post by 24c »

I have a four cylinder motorcycle now blessed with a MicroSquirt and today it fired up for a short time.

Idle was slow, and throttle response non existent, but I put that down to noob configuration...2 squirts alternating per cycle.. :oops:

Anyway back OT, I have two ignition tachs, that relate to the 1&4, and 2&3 cylinders, and their wasted spark is set up accordingly. My question is I have paired up the injectors to squirt on 1&4 and 2&3 together. Is that what most of you guys would have done?

I looked in the manual covering 2.88, and one of the injection firing diagrams doesn't make sense to me, (noob :? ). I would have thought that if the injections are timed to the tach events, on my dual spark set up, I would have a tach event that relates to 1&4 on bank 1 and a tach event for 2&3 on bank 2 .

Can anybody explain it better please, because I am confused.

PS Can anybody point me in the right direction for learning more about Alpha-N.
