Disclaimer: You accept responsibility and risks of any tunes and added features by M-Engineering. If you are not the end user of the car, you will be solely responsible for notifying the purchaser and/or customer they also accept the responsibility and risks of these and M-Engineering is not liable. M-Engineering is also not liable for voided warranties due to installation of our products.
Follow the below instructions at your own risk. We are not responsible for damages. If you don’t feel comfortable removing the ECU's on your own take it to a shop!
When the ECUs are removed from your car DO NOT START YOUR VEHICLE OR KEY-ON. You will need to make sure your car is parked and in a position where you don’t need to move it until you’ve reinstalled it.

Step 1: Remove negative battery terminal and remove wheels and wheel arch liners
Preferably on a lift or in a space where the vehicle can be parked while the ECU’s are removed, take off the rear wheels and both rear wheel arch liners. You will also want to go to the passenger’s side footwell in the interior of the car, remove the battery cover panel, and unplug the negative terminal.
Step 2: Locating the ECU’s.
The ECU’s are located high above the upper portion of the wheel arches. There is one on the driver’s side and also one on the passenger’s side. You will notice a blocking plate in the upper portion of the wheel arches, behind the plate is where each ECU is located. Both ECU’s must be removed for tuning.
Step 3: Remove ECU Plates
Using your T30 Torx Bit and your 8mm socket, remove the bolts that hold on the ECU plates as well as the bolts that hold the ECU to the chassis. These plates are painted so take caution and care when removing them.
Step 4: Removing the ECU’s
Removing the ECU’s is fairly straight forward. On the passenger’s side, simply maneuver the ECU until it is out of the hole from above. From there you can unseat the harness. On the driver’s side ECU, there is another set of connectors on the side of the ECU. These connectors need to be unfastened before you can wiggle the ECU out of the hole. You will need to get a small pick to lift up on the connectors and pull them towards you so that they come off.
Step 5: Label the ECU’s and ship them to M-Engineering.
IT IS VITAL to label the ECU’s with the corresponding Driver’s and Passenger’s Side Markings as to not get them mixed up.
Once you have the ECU’s labeled, mail them to us so that we can flash them and send them back. All ECU’s are returned with next-day air shipping or international expedited. Most ECU’s are completed the same or next business day once they are received by M-Engineering.

IMPORTANT NOTICE AND CAUTION FOR THE SF90
When the ECU’s are removed from the car, it is likely that the 12v battery will fully discharge or act as though discharged, possibly even if you removed the negative terminal. If this occurs, the lights will not turn on, doors will not latch, dash will not light up, it’s as if the car is totally dead. If this happens, after ECU reinstall, simply go to the footwell on the passenger side of the car, remove the cover for the 12v battery, and put a jump box on the battery. This should bring it back to life and you can start the car per normal.
