Performance flash tune for 2009-2011 BMW E90 335D models.

We have 2 methods of having this tune installed (Flash Type Selection).

BENCH (Recommended): Remove the DDE/ECU and mail it in. We will create a full backup 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 backup of the entire ECU content.

REMOTE FLASH: No downtime!!! With this option, once an order is placed, we will ship you a cable, that cable connects to your vehicle's OBD2 port and USB port on the laptop. The remote flash option includes the cost of the cable (which is yours to keep). 

-We will send you a link to download our OBD2 flasher software, and your tuning file in an email after your order is placed. You can flash it your self anytime you'd like, if you have technical difficulties and cant figure it out, we can connect remotely via TeamViewer and assist. Be sure to type in your VIN at checkout to help speed up the process of your tuning file. 

-*You will need a Windows 8 or newer laptop  (Apple, Chromebooks are not supported)* 

-INPA/Bimmergeeks K+DCAN cable will also work if you already have one. In that case, leave us a note at checkout. 

Please print out the form below and mail it in with your DDE. DDE will NOT be flashed until the form is filled out and sent to us. Thank you.
