Interesting thread relating to injector dead time variation.
 

From the Megasquirt Support Forums. Source of inaccurate dead times related to voltage variations and smoothing.

An adjustment has been made on the upcoming firmware to enable you to bypass the code responsible.

I was about to open a thread about small pulsewidth deadtimes.
I installed some brand new ID1050x and I'm running the dead time curve they supply, but if I plug in the small pulsewidth info they provide, the car won't idle for shit. I wonder if this delay has something to do with it.

I also get light sputters while idling but I thought that was a limitation of the injector size. I'll try the new firmware as soon as I can.
