Re: it does sound like a fueling issue.. Posted by kenS [Email] ![]() ![]() In Reply to: Re: Isn't this the year there is a two stage or booster.., JamieP, Tue, 7 Apr 2015 18:32:31 Members do not see ads below this line. - Help Keep This Site Online - Signup |
I checked my setup this morning, on a long freeway commute, it's closed loop almost all of the time, AFR cycling between 14.3-14.8. Release throttle and it will briefly go rich, to 10-11 or so. At WOT (very briefly, on a ramp) it will go to 12 or so (but this happens so quickly it is hard to follow reading the gauge, before it goes back to close loop). And I have much smaller injectors (the Ford 21#, almost stock) than you do. I have a Bell FPR which will boost fuel pressure a bit under load. With your larger injectors & RRFPR you should have no problem driving the AFR to way-rich...
Are you reading AFR directly off the gauge while driving, or are you logging the output so you can look at it in greater detail afterwards?
