This tune upgrade is for 2009-2011 BMW E90 335D models for customer that already have our tune installed on their E70 X5 35D and are upgrading to the next step up.
We have several upgrade options to choose from for your E70 X5 35D M57
We have 2 methods of having this tune upgrade installed (Flash Type Selection).
Method 1 - BENCH: Remove the DDE/ECU and mail it in. We will create a full back up image of your ECU without opening the lid or any physical damage to the ECU at all. We then upload our tune of your choice and mail the DDE/ECU back. This is the safest way, as we can have a full back up of the entire ecu content.
Method 2 - REMOTE FLASH: No downtime!We have an available option of flashing your ECU/DDE remotely through the OBD2 port of you vehicle without removal of the ECU/DDE. The remote flash cost includes an OBD2 cable that you can keep. If we run out of stock of the remote flash cables, we can offer a cable for rental with a deposit to still do the tune remotely.
