Title: distributor question
Post by: jcassity on October 05, 2014, 11:44:53 AM
the piece of the dizzy that is under the rotor button, the round finned thing that passes through the stator............

when the stator magnetic field is not obstructed , does that determine the "ON" state or is the open window considered to the computer "Off"

if the answer is the open window determines "ON" , then lets assume someone had .001 or less aggressive but .0005 metal removed so the opening is this much wider?

what would happen,, injectors stay on a tad longer ??

It would just signal the computer to fire a bit earlier. Not any different then slightly increasing timing. The computer dictates fuel. The pip just dictates when the #1 is fired, following the rest sequentially.

I thought the opening "width" was engineered and equal for a reason (excluding cyl 1) so the time the pulse is modulated is proportional to the opening....??

Either way, the computer would still dictate the actual fuel flow. Even if you did increase when the injector opened, the computer would compensate.

It's different so the pip can signal the computer when cylinder #1 is coming up for the sequential injection. Changing it will not make a difference or increase performance. If it did people would have done it already. The only way to increase the injector pulse rate is to change it in the computer.
