Ranger Mods

Wanting to understand more about what (if any) module re-learn I could or should be triggering via Forscan, and when & why.

Have done an EGR mod, planning things like DPF back exhaust, ECU remap, snorkel etc. Also I got my PX3 at 80,000kms so would like to re-train it to drive my way and remove any history from the previous owner, if that makes sense.

So what modules should I trigger a re-learn on?
Any benefit do doing any on a schedule? Or just once since the main driver has changed?
What should I do after each of the above planned mods?

Thanks

Overall the vehicle is always learning. It is going to adapt to change so there is generally no need to do anything.
I may reset some values here and there but usually only if there is an issue present or if injectors are replaced.

Personally, clear any fault codes that may be present and let it learn. I ran so many engine and trans tunes through my old vehicle, testing over the years and every time I could tell a difference without clearing data.

As for anything that my say relearn it is usually for related to config changes that are not applicable to you so there is no need.
