I have a tune for my z from my tuner and he only
Used two of my 5 maps..i was wondering
If a diffrent tuner from another shop can adjust my other maps while keeping the tunes from shop A..

 

It all depends if your orginal tuner locked your ecu or not, it they didnt they lock it another tuner should be able to mess with the other maps.

 

Short answer no.

The only exception is if they can get the original tuner to release an unlocked copy of the rom to them so they can tune the other maps. There is no way to modify the tune that is currently on the ECU without having the rom file on your computer.

 

Also remember than some settings are shared between the 5 tunes so u cannot change these in different maps...So u cannot use totally different strategies...
