Yes, my understanding is that it does that.
When the lambda sensor was changed previously VX wiped the memory of learned parameters, it runs rough for a short while and then settles down. You are supposed to take it out for a 'normal' run (I am told) to help it relearn the norms.

Lol, this just highlights the lack of understanding.

All they can wipe (reset actualy) are a few block learn parameters, the standard maps etc remain.

The block learn values are used to modify the standard map values to obtian a better optimum for the engine running dependent on condition etc.

Yes, I think we are saying the same thing but with different terminology. The basic map/algorithm/firmware will be standard for all cars but each engine will be slightly different, as each replacement part will be. So these are learnt/tweaked by the ECU to optimise the running.
Do you think it is necessary to wipe? Or is it just, fit new part and let it relearn
 :question

It should relearn itself fairly quickly anyway

Thanks

Good info
