When left the gas over 4000rpm, CEL turns on and get O2 ..
Hi, i have a problem when i go over 100km/h and 4000rpm and left the gas, the Cel turns on and get this: How could i solve this problem? This happens some times, not always. I have to turn off ignition and on again to clear cel or Ctrl+u to clear code errors. It happens in the b18c4 and with the turbo, in both cars.

disable the stock o2 sensor and problem should be solved, you dont want closed loop corrections while you are tuning anyways. disable closed loop also

I only have installed the Uego wideband sensor to D10 Port and configured in settings with offset correction and Aem selected. Dont have narrowband sensor, only the uego. Where can i disable the narrow stock sensor if is activated? I want the closeloop activated below 750mbar to get a lower consumption in city. Thanks for answer.

I have checked this options. I cant see any option to disable o2 stock sensor I only see the closeloop + ve corrections (stock)... but i want that the ecu make corrections to get lower consumptions.

Yes, i know that when you are tunning must do in openloop to get nice and real values, but the problem exists when i ridding without laptop and no tunning, and must have activated the closeloop to get lower consumption of fuel.

If you can get on a dyno with speed holding you can tune the car so it's actually alot better on fuel left in openloop than putting back in closedloop. It's very hard to hit the low load cells and hold it there road tuning which is why I suggest a Dyno for this.sIrK wrote:Yes, i know that when you are tunning must do in openloop to get nice and real values, but the problem exists when i ridding without laptop and no tunning, and must have activated the closeloop to get lower consumption of fuel.
In this case, i dont want to tune the low cells below 300mbar... only wants to avoid the CEL light on and o2 sensor error. I told that when im running over 100km/h ie, and going over 10% of gas maintaining this speed and left the gas, the engine is retaining and in some cases the CEL turns on and protection is activated... I want to avoid this situations... and i dont know how disable o2 stock sensor (i think that is this), because i only have installed a wideband sensor in D10 port and configurated in settings as AEM with offset correction.

FYI after tuning I was able to get 42mpg @90mph for a whole tank of gas.... Running open loop. I personally don't like the fact that the ecu has to go rich and go lean every few milliseconds, that's wasted fuel IMHO.... But it took a few months of light throttle street tuning to get to that point.

I have marked the \"Disable O2 Heater\" and \"Wideband as closeloop input\" because i have only the uego installed as o2 sensor. I show you my settings (Wideband input is in D12 because in red civic have installed in D12 and in grey(Turbo)civic have installed in D10):

Why do you set the correction trim at 0%? and how could be the best options to get the lowest comsumption? Could i solve the problem installing the stock o2 sensor and maintaining the wideband too? Today i went in the car over 50kms and 2 times had to turn off ignition and on to clear CEL.
