i think i have found another way to "guess and test" the injector constant. this requires you to be able to get the car to run with the injector swap. calculate or monitor your afr error rate at a reference point (idling fully warmed up, locked in open loop for example), then make a change to the idle ve table and re-monitor to see what happened. if the injector constant is wrong, ve percentages and afr error percentages are not proportional to each other and may over or undercompensate. you may change the box by 5% (not table value +5) and might get 1% more error or 10% more error. when the two are proportional you've found pretty close to an ideal injector constant.



"...and then God said let the 2.2's have potential. Thats when hell broke loose..."

that may work, but you can calculate the "pretty close to an ideal" injector constant on the first try witout collecting data using the FAQ on the HPTuners forum
