I didn't post my experience to tell you that's your problem. The point I tried to make was that the ECU adapts over time for any rich or lean base condition. In my case, I was rich- clogged air filters.So the ECU adapted lean. In your case, you may have a lean condition and it is adapting rich. That's all I was trying to say. I'm curious to see if your problem comes back after some time. As far as anyone with any credentials to explain our engine ECU's..unless you can find a BOSCH engineer from Germany to get on here and post...well, good luck!

Open loop only or both closed and open? Dont drive that ****er if it's you are seeing that rich not at WOT. I'd reach out to RaceIQ, tell them what you did and see if they have any ideas. Maybe try resetting by unplugging battery for 10 mins then reconnecting also.

thanks for the help, but the video showed a rich condition, and it def wasn't a air filter problem. I got a huge problem with this platform and thats the ecu. Nobody has the credentials to point out why the ecu does what it does. Im telling you this because nobody gave me the advice to remove the battery and replug, that was me guessing. It goes to show how bad this platform is once something goes wrong, ecu and tuning wise. I had people tell me, Spark plugs, Fuel injectors, engine has damage, boost leak, and it ended up being a ecu thing. Imagine how frustrating that is, you spend all that money to fix a problem meanwhile all it was was to remove a battery and replug. My Theory is by removing the battery it resets the fuel trims, ALSO BIG BIG MISCONCEPTION RDY!!!!???? adding a NEW TUNE or REFLASHING will not do this for you because when i had my rich problem it didnt work switching tunes around, i took the time to switch tunes to rule this theory out. Now when someone says I'm wrong well they barely have any evidence to prove I'm wrong, its all talk on this platform.Thinking back, Nobody could believe that harness fixed my old lean issue with the recall pump. Talking to all the people who gave me wrong advice, they couldn't believe that this battery trick worked. Im not blaming the tune, nor the software, I'm blaming the car, Tony is a great tuner. If someone has evidence its the tune, well posting a story here is not enough, post a vid on youtube and show the steps to fixing the software error and provide evidence to why its tune related.
Thank you for saying that. Tony has been awesome and is a great tuner. I love my tunes!

I loaded a race tune from Tony and had 10.0 AFR during 3rd gear pull. Then I read this and disconnected the + battery and discharged it. Waited 30 min and reconnected. Immediately did a 3rd gear and AFR was 12.5-8. Works now!
