ETC go WOT at light acceleration
hi guys
i have problem with my car tune
im not tuner or professional
but im trying to learning and tuning my car
so my car is 2010 mercury grand marquis which is the same as crown Victoria
the most popular police car
i installed AFE cold air intake And i calibrated my maf with maf\LTFT+STFT histogram
so my car runs fine but i notice something get me confused
at cruising or stopped at light when i try to light or mid acceleration
the car for second's feel heavy and i hear the intake too loud
after that the car back to normal
i used scanner to dataloging my car
so you can see accelerator pedal with tps
at some areas shows the ETC acting not right and spark drop to much in negative side
i don t know why
is it related to torque management tables
so can you guys help me
to find what is the wrong with my car
thanks a lot and I apologies
my English not that much
the problem at 10:00 u can see it in the file
*knock sensor not right my exhaust manifold leaks
not correct because when it knocking i can hear it
the knock sensor shows knock at stock file with sock tune and premium fuel.
so don t worry about it at all
thanks
