I just did a read out of the ecu on my newly aquiered Evo 9.
It appears it has the tephra patch on the ecu already.

I'm just trying to add the nlts setting.

It was disabled (set to 0)

But I noticed the rpm drop setting was not on the list .

I set the nlts to 1 to enable, but sill no rpm drop setting

Is this just a old version? Or am I missing something else .
