Automatic gearbox 6HP Audi a4 b7

[reb00]

Hello,

what is the cheapest way to modify 6HP maps in Audi? There is a xhp tool for bmw, but why there is no such a thing for Audi? Is it even possible to make it through OBD?

can be done by flex. Can be done obd but i would prefer bench to do.
i done several times without problem via obd but i also know people which brick em obd.

Thank you for the update. TCU is inside the gearbox in this case, am I right?
What is your opinion after mod? I can't get used to this slipping clutch on 1st, 2nd, 3rd gears and slow changing on full load. Is there really a difference after boosting oil pressure on lock up and valves?
Also if i decide to modify the ECU is it needed to update the torque in TCU, or adaptation will be enough?
