Technical N54 ST AFR/Trimms

[Corne]

Good evening from South Africa.

I have a question.

Why does it seem that AFR(1) and Trimms2 work together and AFR2 and Trims(1) work together?
Every time I blow lambdas lets say Bank 1 lambda goes out, fuel trimms on bank 2 will go bonkers.
I have MSD80 ECU.

Thank you and regards.
Correl.

I have asked Terry Burgers this and he acknowledged the the question but provided no answer. Something is obviously swapped in the firmware to avoid some sort of error.
This on a jb4 flash?

Hi.
Yes, its on the normal BMS ST flash from N54Tech.
I thought it maybe had something to do with the MSD80 ECU but I think its the same on the MSD81.
I'm looking for someone that can build me a flash for my car but there are no good tuners in my country that knows these cars with single turbos

Mines ms80 to.
Its weird.

Doesnt affect power but is annoying for trouble shooting.
