Audi Q7 2012 4,2TDi CCFC ChipTuning.
 

My car is AUDI Q7 4,2TDi 2012 engine:CCFC and transmission:Aisin AL1000
My car engine ECUs chipped but the transmission not chipped,must I chip the transmission too or not? The person who chipped my car engine ecu,told me "there was no need to chip transmission ecu",is this right or not???

of course
