Help with catless dp codes
2008 335xi
Arm 5 in DCI Catless dp Stage 1 MHD 93oct 162,000 miles Kinda new into the tuning world haha so need some help from someone that really knows about logs Recently went catless and tuned the car with MHD and am still getting catalytic codes 2c7c 2c7b Thought MHD fixed this with the dp fix in the settings so why is it showing up My next thought is are my 02 sensors after the cat needing to be replaced maybe fill of gunk from the exhaust ? Here are my logs 3rd gear pull and let off 3rd gear pull let off And here’s at idle idle |

I had something similar just happen, first assuming you picked Aftermarket DP's in the pulldown and not OEM catted DP's.
I had flashed back to stop (long write) for emissions check and then flashed back to stage 2+ no change of settings and it was aftermarket DP's selected and a couple drives later I get a check engine and cat efficiency codes, I double checked and aftermarket DP's were selected so I should not have gotten the codes. I reflashed again and so far so good, need a couple more drives, but there is some weird bug I experienced and you seem to be experiencing the same.

So CUREENTLY RUNNING stage 2+ on AFTERMARKET DP in settings and to clear those code do 1. So go into stage 2+ then in exhaust setting set it to OEM CATS,then FLASH IT Then 2. Go back into stage 2+ and set exhaust settings back to AFTERMARKET DP,FLASH IT again And it should work ? Kinda new to this haha |

I didn't even flash in between, just connected and changed the setting to OEM then changed back to aftermarket/catless then flashed again and all seems fine now. Won't hurt flashing in between, but it does seem there was some bug with mine where it flashed it to OEM cats even though it wasn't selected as that so just changing it and re-flashing made the setting stick.
