I think it was a mistake to change the dde isn. If the transmission is automatic, it will also have an isn that must match as well.
It is better to change the isn inside the FEM. Read the dde isn & write it to the FEM.
After updating the FA, did you check if software in FEM is correct?

EGS is not a problem right now i will fix it later,
but right now ISN of FEM and DDE are correct
i think i need to update software of FEM,
should i do that with Ista ?
