0x3A1DE0 error code after replacing OEM headers

(1/1)

Hi All
I've replace my 2024 S1000XR OEM headers with an Akrapovic, and now have a full system on the bike. I had no error codes come up initially, but after a few rides an Engine Control error (XBMS01) came up. If I check the engine controller error details if shows 0x3A1DE0 & 0x3A1EF0 with descriptions "Catalyst, Bank 1 & 2, conversion, efficiency below threshold". I can reset these errors with the 911, but eventually they reappear after a few stop/starts.
I assume it's because the catalytic converter is now removed and the Lambda sensors are picking this up. In the "live data" there are Lambda control factors set to 1, so not sure if these values needs to be changed or adjusted. Any advice will be appreciated.

Hi,

I had the similar problem on my 2024 S1000XR when I changed to an Arrow Headers. Still finding for an answer to this problem.

I'll be taking it for an ECU remap and dyno shortly, was told this will fix it. Will keep you posted on the outcome
