• ECU Unlocks are typically completed SAME-DAY they are received at Unitronic HQ.

• Depending on the shipping methods you choose, you can have your ECU back in your hands within as little as 48-hours.

Once the MG1CS164 ECU is unlocked, users can also tune their vehicles directly through the OBD-2 port within minutes, from the comfort of their own home or garage with UniCONNECT+.


*15% or $150 with the purchase of a NEW ECU or TCU Unitronic Performance Software only. Not available on Upgrades or FLEX / UAF add-ons. Cannot be combined with any other promotions. For example, you cannot add 15% or $150 OFF your NEW TCU tune on top of the DSG® Combo discount. But you can save 15% or $150 on your ECU tune and still use the $150 DSG® Combo discount on your TCU tune for even greater savings!
