heres a quick log, why would it be running like that, as soon as i put it to 0 or any other percent but 50 it runs like shit or dies, not even 49% works.

ive already posted my cars specs like a mill times but, 94 accord, f23a1 swap, 5spd f22trans, converted to obd1, s300 chipped p06 ecu. stock with CAI, full custom exhaust, thats all. non of that should matter seing as its stock, and should run without added trim. i just want to know what couldve possible went wrong for it to need all that fuel, and im gettin crappy gas mileage.

Perhaps you have the fuel line that connects the fuel rail connected improoperly (washers missing or in wrong place) and it is severly restricting fuel flow.

not a chance, plus it deffinitely using all the extra fuel considering my gas mileage is like 10 miles to the gallon, (exaggerated.) i am gonna try and change out injectors cause i have a feeling one isnt spraying enough, they all sound like theyre working and all show correct voltage, but one screen may be clogged.

pulled injectors today and found 3 outta 4 top filters were clogged, so i switched out my injectors and filters now runs fine without any trim. thanks for the input tho.
