overfueling, please help
which is the sensors that call to ecu for overfueling.
I abjust fuel pressure at 3.5bar without pipe, chip is from msd , i abjust CO screw 1 turn anti clock side, but the engine is overfuel and the spark plugs is fluided. At 1000 rpm it vibrate. i abjust rpm at iddle at 1300 rpm but the vibration stays. i am with champion qc59c spark plug and once i fluided them with gasoline.How can i understand from where came my problem ?

Check the MAP hose is actually connected and secondly the hose is in good condition I.E no splits, that connects to the plenum, sensor is under a fender under the header tank.
Phase sensor can also cause over fueling but car will run without it although not good as injectors run batch rather than seq injection.
I assume the engine runs as you have checked FP?

what is the base co content?
what ECU is it? anti clock may not be weaken!
is the phase sensor gapped and aligned correctly?
is the crank sensor gapped correctly?
does tha act sensor function correctly?
does the ect function correctly?
do you have the correct map sensor and does it work correctly?
are you sure you have the correct injectors?
do you have any air leaks on the vaccum side of the t/b
is the tps calibrated correctly?
was the chip ordered to match your exact engine spec?
did he chip come with instructions? and have you followed them acuratly?
if the answer to all of rhese is yes, email your invoice number and chip id over to sales@remapping.co.uk and we can help
