i went blow thru. my fuel trims and O2 trims have been at 100% since i have had the car (my ecu is stuck in open loop).
so i bought a second O2 sensor (for the rear manifold, connects up by the fuel rail) because i initially only had the front one hooked up.
i have a blow thru setup, everything is set correctly. my question is, how long will it take for my ecu to "learn" the correct fuel trims? O2 trims are changing while its running now.
i have heard that the fuel trims can change very quickly, but i have also heard stories of the ecu taking a long time to "learn" after being reset. what say you?
thanks
