#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?
