Hello all, I'm in need of some help. Is a 3.8-4.2ms injector pulse width normal at idle and correct?
I have a 2000 4.8/4l60 po1 that ran great, I then put a 228/230 585 112 cam in it with PAC 1218's, racetronix/lucas 42lb injectors, long tube headers. I can not get this thing to run right, idle pulse width's seem high to me from what I have read. Still has factory converter, 3200 enroute. I can get it to idle decent in park at 800 rpm's wide band 13.5-14.2 but when I put it in gear it idles way down, wide band goes lean, injector pulse width's go up and it runs like shit or stall's. I have played with the injector flow from 36-55, I have added up to 50% to the offset in both directions, can not get the pulse width's to go down. What am I doing wrong? here are a couple tunes and logs.
