Milltek Active Valve Control for Lotus Emira V6 & I4

Milltek wireless exhaust Valve control unit. 

Increase the exhaust note of your Emira when and where you want!   The original valve control limits the valve opening a lot and doesnt fully open it until high rpms giving a very muted sound profile. 

Fitment for all 3.5L V6 & I4 AMG Emira's! 

Install is a very easy 45min job:    

• Remove the diffuser panel
• Unplug the electrical connection at the exhaust valve next to the muffler
• Plug in the valve controller to the valve itself and to the original harness plug
• Cable tie or fasten the control box up out of the way as you see fit --just be sure not to mount it too close to the exhaust itself. Up in the bumper area is ideal
• Reinstall the diffuser panel
• Pro-Tip -- You can program the remote button/s to your homelink if you dont want to use the little fob.  

The controller has three buttons: 

1- Valve open 100% 

2- Valve closed 100%  

3- OEM valve control -- valve runs just as it does stock. 

Some controllers have been reported to have #2 and #3 opposite of this. The best thing to do to verify is start the car, put it in sport mode and then while next the exhaust outlet press #2 and then #3.  See which one closes the valve and which one keeps the sound the same.  

Valve closed 100% is not recommended to use except for lower rpms/idle situations, otherwise use oem mode. 

A couple of programming options as noted from Milltek: 

The valve remote can be programmed to change the start mode.
If you want the vehicle to start in the last used mode you need to press button #1 5 times within 5 seconds.
If you want the vehicle to start in a specific mode you need to press and hold the relevant button for 10 seconds.
The flaps will open and close 5 times to confirm the start mode programming.
