hello there.

i have installed an apexi turbo timer on my impreza because i had one in my evo and it worked great.

everything was fine apart the afr simulator function.

the display shows a constant 14.6 and the red and green leds flash intermitently which according the the users manual states that the sensor has not yet warmed to working temperature. i drove the car for around 20 minutes (slow mode) and i still couldnt get any values. my evo would get values around 5/7 minutes driving.

in the case of my evo, the ecu wiring was different from LHD to RHD. the instructions were RHD wiring and my car was a europe spec LHD wiring. after i performed the swap of the wires, everything worked great.

my possibilities right now are:

faulty O2 sensor (i doubt this, because it would lit my CEL)

different LHD and RHD ecu wirings as my car is a europe spec gc8 with EJ207 218ps spec (i installed the black TT ground wire in the blue plug (RH side one) on the second wire from above/first wire from left and the white voltage wire from the TT in the same plug on the third wire from above and third wire from right (just as stated in the TT instructions manual).

if anyone could shed some light, i would be thankful.

can anyone help?

i have used this wiring, that i for sure for uk and japan spec.




is the euro spec LHD, the same?

please help

well, i took a multimeter and started checking if there was something wrong.

i came to the conclusion that the voltage in the o2 sensor wires is not steady

even at normal temperature, the sensor was providing, 0.7v, 0.1v, 0.3v, 0.6v.

it doesnt go steady.

any help?

 

cant anyone give me a hint?

could it be a faulty o2 sensor? shouldnt it have lit the CEL?

 

i have tried to replace the o2 sensor and i get the same readings. can anyone shed a light?

please?
