Hi I have just checked car for error codes and came up with the u1900 error code what should I do I have cleared it but have seen it before. Is it something to do with my bluefin remap? I run stage 1 and now again stage 2.

Thanks all

i think u1900 comes up when you have mapped the car, D900 is another one so i wouldnt worry too much, i think it basically means the ecu has been tampered with
