my car has narrowband simulated through link and I have a AEM wideband hooked up to ecu. If my wideband sensor is taking a crap will this cause the car to run like crap as well??

How so? Please explain I’m too curious. I’ve had wideband sensor crap on me before but the car ran fine l
Crap “loss of power randomly”. I don’t have 02 sensor it’s being simulated through LINK. Only have the 02 for wideband hooked upYou kinda need to define that though. Bad o2. Ecu doesn't know what to do so it will default rich. WOT ecu doesn't look at o2.
So what does " run like crap" mean
So the ECU uses the wideband 02 for feedback?I just explained. Without o2 feedback ecu can't shoot for stoic at part throttle
Umm....well you stated you simulate o2 narrow band. So yes in that case it does.So the ECU uses the wideband 02 for feedback?
Ok thanks man! Just looking for knowledge!!!Umm....well you stated you simulate o2 narrow band. So yes in that case it does.
I don't think you understand how this works. Ecu can't use a wideband input. Ecmlink allows you to take the wideband input and "simulate" narrowband.Crap “loss of power randomly”. I don’t have 02 sensor it’s being simulated through LINK. Only have the 02 for wideband hooked up
The wideband reads completely lean under any load, OR it’ll read 13.3 constantly under any load or it’ll be erratic jumping around rapidly.I don't think you understand how this works. Ecu can't use a wideband input. Ecmlink allows you to take the wideband input and "simulate" narrowband.
Random loss of power? Probably not.
How do you know wideband is going out? Logged it?
Check what exactly? That the wideband is culprit for partial throttle issue?You could always slip the old sensor back in just to check
Yes. Likely it is.Check what exactly? That the wideband is culprit for partial throttle issue?
It should be! Started happening as soon as sensor went haywire. Thanks will report back sometime this week. You were very helpfulYes. Likely it is.
It jumps around with car offTo test the wideband sensor, with the car off and key on. The gauge should max out or read---. Next take the sensor out and soak a paper towel in rubbing alcohol and gauge should read 10
Hmm, after a few seconds it's still jumping around? Is your o2 in the front or rear? I would try the rubbing alcohol test. Let me know what happens then.It jumps around with car off
Wiring harness?Update: swapped wideband sensor, same results, must add that it stays at 14.8 with car off
The gauge being bad only justifies your false readings. It doesn't justify the engine running like shit.Tuner says gauge is bad??
