Any actual information out there on recall 24E12? Lots of internet rumors ranging from massive MPG gains to immediate cat failure after getting the PCM flash. I'll probably get it done anyways but sure would be P.O.'d if my cats went bad after....
I just recently had the 24E12 recall done on my 2020. My fuel mileage has increased. In my opinion, they leaned out the fuel mixture. I think that the too rich fuel mixture was cooking the catalytic converter.
