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

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.
