Wideband closed loop
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.
Re: Wideband closed loop
Are you trying to run closed loop form the aftermarket wideband?

Re: Wideband closed loop
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?
Re: Wideband closed loop
Is the factory wideband still installed and functioning?

Re: Wideband closed loop
Primary o2 is still there and enabled. Secondary removed disabled and replaced with the wideband.
Re: Wideband closed loop
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.

Re: Wideband closed loop
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.

Re: Wideband closed loop
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.
