I just uploaded a new calibration from my tuner and now I have a cel for secondary o2. I checked the parameters and under the closed loop tab, closed loop is unchecked and secondary o2 is enabled. Shouldn't closed loop be checked and secondary o2 disabled?

Also I know I had lean protection on my previous calibration, but that isn't setup now. I have a call/email into my tuner, but I thought I'd post this to try an figure it out asap.

I'm using an AEM wideband. Any thoughts?

 

You can have closed loop checked or unchecked it doesn't matter. Mine is set up the same way as yours and I don't get a CEL. Interesting. Using the secondary 02 is because of how the KPro is wired but it still uses the first one as the primary.

 

Yea I don't know why the he would've changed the parameters because he just made adjustments to partial throttle tuning. Hopefully he gets back to me soon because I don't want to drive the car with the cel and the lean protection not set.

 

Is lean protection the same as lean cut?

If so, you cant have it with a non-rsx wideband.

 

I believe so, but my tuner said he setup lean protection

 

With Kpro do you have to run both O2 sensors?

 

No you dont have to run both stock o2 sensors.

Pretty sure thats not possible OP. Probably would get more affirmative answer in the engine management forum.

 

You cannot run lean protection on a PRA calibration which is what you must use if you are running a narrowband o2 sensor. If you wire in the RSX wideband, you can use the PRB and the option to setup lean protection will be available.

There is an option to turn off the the readiness codes for the secondary o2, but I can't remember what it is. But if you're running open loop, it doesn't matter anyway.

 

Trying to figure this out with my tuner now. For some reason between software versions all of the settings did not transfer over, so when he sent over the adjusted map some parameters were different.

Still not sure how he's running lean protection though. We'll see when it's all said and done.

 

There was a new update from this month, make sure our on the latest version.

Im new to Kpro, I installed it today Any idea where I can get the sub harness from for it? (Sorry for thread jacking!)
