Hello, I’m new, but I’ve been reading these forums from I’ve gotten my car 2 years ago. I have the speedtech Single turbo (top mount kit with reflex controller. I’ve been trying to get the car tuned/Dialed in but I keep running into this issue when trying to grab a log for the tuner. I have Single o2 bank fueling enabled on mhd and I also have adv o2 sensor. Bank 2 o2 sensors are unplugged top & bottom. If I reset the lambda adaptations my AFR reads fine then maybe after a few minutes of driving it it starts reading lean when it throws these codes. I have purchased a heat sync that should be on the way. I’m on my 3rd adv o2 sensor. Does anyone know why the Car keeps doing this?
