I installed a wideband in the car. wideband output into a egr pin. the ecus sees the wideband. not much offset between the gauge and software. I have tuned the car with the new camshaft. Wideband closed loop doesnt seem to work at WOT. There are a few spots that seem to run a little leaner then i have tuned it for between 5500-6000. Ecu is not targeting or adding fuel in open loop. I have overlay lambda input open loop analog wideband selected and all other parameters selected correctly for it work.

Are you trying to run closed loop form the aftermarket wideband?

Under settings - lambda overlay - overlay input - open loop analog wideband. That’s what I have selected. Under the closed loop setting there is no option for that. Just wideband lambda input. Which imhabe it on egrl - EGR Lift. Am I missing something?

Is the factory wideband still installed and functioning?

Primary o2 is still there and enabled. Secondary removed disabled and replaced with the wideband.

You can only run closed loop from the factory wideband and not from an aftermarket wideband. The aftermarket wideband can only be used for datalogging purposes. I do not believe that the Fit will run in closed loop at wide open throttle.

I m referring to the engine running in open loop for wideband closed loop control. It doesn’t work. Ecu is not adding or trimming fuel after I tuned it @WOT.
I was assuming that the ecu would add +\- 1% with wideband input into ecu. So basically you are telling me wideband closed loop doesn’t work at WOT.

i dont understand why that option would even be available in the software. kinda sucks i bought a wideband and installed it just for that feature.
