Just installed ecmlink v3 and front o2 was not cycling. Staying constant at .80 volts at idle cruising and wot. So i replaced the o2 being that it was probably original with a brand new bosch and im still getting the same readings. Stft is 5% until i pass 4k rpm and the ltft low is -12.5. Afr at idle locked in open loop is 13.5 and if i unlock and let it go into closed loop the stft goes even further and the afr at idle shoots right to 20. No matter what i do the car doesnt react. I know this has been asked so many times already and im new to the dsm community so any help is much appreciated, i just want to get the car running correctly, thank you.
