Year ago I bought Civic 6gen with B16A engine and Hondata S300. Car was tuned up and for the first time I was really happy. But one day I compare my car and another B16A, we go almost quarter mile and I lose about 2 or 3 seconds.
I try to find out "Why I lose so much!?". I replace many parts(spark-plugs, pressure regulator, DISTRIBUTOR, injectors, intake filter) without any results.
Now I searching for problems in my calibration and I found something.
On this picture from my datalog you can see strange Injector pulse width after I shifting gear and smashing gas, in first second AFR is good(12.94) but in next second AFR become 10.5 and slowly go to 12.5 when it happens car start jerking.
So the question about Injector pulse width. Why after I smash the gas Injector pulse width grow up, I don't have any Throttle tip in trim in my calibration and as you can see Injector pulse width grows more if I shifting to the high gear.
