Max ECU controlled duty cycle on stock computer
 

What is the Maximum ECU controlled duty cycle on the stock ECU?

there is no max persay...
the ECU can run your injectors all the way to 100% duty with enough boost or fuel correction with a fuel computer..

My car is a n/a with a lot of mods. I was wondering if there is a point on the srock ECU that no matter what kind imputs the comp gets telling it that it needs more, it won't increase the duty cycle past that.

Thanx for this post i have been waiting for the same question and answer for so long..:)

rotary performance says the stock n/a ecu only runs between 59%-63% duty cycle on the injectors, kinda low, but the injectors last long :) i think they say 85% is where they get unreliable
