sorry, i should have qualified what i said better
when i said "the only changes
they can make", they was referring to the original applications in first post, not consult2 ones like cipher
consult 1 capabilities, unlike consult 2, are limited to changes to the ecu only whilst running and are lost when the car is turned off.
those with consult 2 cars can have adjustments made that arent lost (like the timing advance).
