Heated NB o2 sensor just got booted.

I don't know about wide band tunning, what ecm and engine set up you running?

You also could have changed something back when that never showed up till you went CL again? That's when I use the Compare option on TunerPro from the bin I'm using now compared to what I originally started from. It will show any difference, even a hex change that is not identified by a parameter!

I use the compare option all the time, nothing really stand out concerning this but I have wondered if something I changed before I attempted cl was the problem.

Does you WBO2 have a NB sim output? You can try that for zero dollars and see if the same thing happens. If it does, it's in the correction, or more than likely a setting, such as the delay function of the NBO2 feedback. If this distance setting is too far off, you can get into a downward spiral where a correction takes place, but because the setting isn't correct, another correct takes place and so on, until the BLMs are at max and the engine is struggling to run.

ECM but didn't leave it since the sensor was mounted so far away from the engine. I have changed the Integrator Delay Vs. Airflow since I am running long tubes and the sensor is in the collector.

It's Tunerpro, I read the other day where some guy called it "simple software" so how hard can it be. LOL!!!!!!!

I have never tuned a 165 ecm so I will stand aside, my 747 and 288 as they go closed loop its like adding 25-50 hp and the mileage goes up an seams like every thing smooths out as it gets to operating temp. ps I only got a 4.3 v6.

Well if WB output is into data stream it could be TP? Well not the software but the conversion for the WB Value.

Can you get the WB into $6E data stream? That would be the way to go. I alwasy use 2 values, one for the voltage as a sanity check and then one for Lambda... AFR if you must...

The WB has been in the datastream for years. The conversion is correct. Plus the way the engine behaves matches the wideband. The WB is not the issue, I even replaced it(controller and all) last year due to this just to be sure.
