I was searching on why my injector duty puses under constant light load... and a couple of people said it was due to the Power-FC when it goes into the closed loop circuit for the O2 sensor.

If I just unplug the sensor will that disable the loop? Or how can I stop that from working.


Also could it be anything else??? The injector duty is pulsing about 4 percent, and it is making my AFR's on the wideband just by about 1!!!

 

Have you ever looked at the ETC-Function screen?

 

Yeah... sorry, I noticed O2 sensor on the settings screen... The Japanese charactor only changed between two so I'm guessing one was on/the other off??? Anyways. it's running 100% better! It doesn't surge, and seems to shift a little better. But I also grounded out the Power-FC box, maybe that helped to?

Do you know what would make is fall flat on it's face when you first shift, also sotimes when you push the gas from an idle...
