Message	..with all this in mind. To grasp the concept i mean. Got to this calculator and play around with it. https://www.stealth316.com/2-calc-idc.htm As an example. At 800 rpm and a pulsewith of 2ms dutycycle is 1.33 % Now if you change rpm to 5000 rpm and KEEP PW at 2ms dutycycle is now 8.33% Just so one doesnt get fooled to think that an increase in dutycycle means an increase in the time the injector is opened. :)
