Seems that change I made to hopefully stop skid control didn't work either in that change of latest file.

Hello

You need to increase Lambda values to get less smoke.

FMTC_trq2qBas should extend torque axis, because of request in Torque limiter.

You don´t need to modify SOI maps at this moment.

Excellent, o.k. that seems back to front to me, but I'll give it a go... I was told because the drivers wish was adjusted below 2000rpm is why it was smoking so much so any tips & advice is appreciated!

Just for reference with extending the torque axis how does this happen as with diesel & general rule of thumb fuel is torque so wouldn't that also be adding fuel?

Yes, you can extrapolate fuel IQ for new torque values.

Also Injector Time map (0x1DCBFA) is decalibrated.

Better put ori values or extrapolate IOT in a similar way as FMTC_trq2qBas.
