#26899, "Fuel setting afc tuning etc help wierd noise"




          

well recently i have been doing some tuning again with my fuel setup since i got some 315cc injectors in for some time.. well i have been leaning it out a bit last couple days datalogging my fuel system.. weird thing happen today.. i drove the car to and from the gym 11-3pm and it was ok, then i just let the car sit for a hour at home, then i decide to go tune a bit more, when i started it up it sounded a bit odd ( like when u put bigger injectors in and dont lower your idle fp or lean on your afc yet)so i look at my pocketlogger and when i look at my dash, my cel is on.. i check it out 'system too lean'. so i thought 'ok' time to richen it up a bit... i do that nothing, so i look at my fuel trim short and long , long fuel trim is max out 24-25% and short trim is working itself up there 10% and going up to 24-25%... so im like wtf? so i check all my fuel lines, nice and tight etc vacuum ok, and i decide to check my super afc wiring at the ecu, seems cool even see if the injectors are leaking seem ok... i try it like 5 times within this time period same thing. then after the afc wire check i start to do it like 2-3 more times, samething.. then finally i start her up one more time, and its normal again?.. each time my fuel trim went 24-25%, & my idle fuel pressure went up to like 38-40psi instead of 28-30psi at idle? but when i rev it up it drops down... anyone have this happen to them? or what would cause this?

Just curious, but how much were you leaning out the settings on the Hi and Lo throttle points with the 315cc injectors?
