I installed this on
Honda Stream

Review
With the D1 Spec AT Shift Controller, my car can now drive through the congested roads of Singapore during peak hours, smooth control on the expressway, and aggressive throttling when on the track! This was totally a delightful device that I found. When on congested roads, I would switch to the economy mode in which it wouldn't hurt to take off slowly, since I know I would come to a stop soon. On expressway, turning on the Sport did the trick for me just fine! Last but not least, this device performs so brilliantly on the track, switching to Sport 3, the throttle output was a blasting experience! Definitely recommended for those who owns a car for both use on local congested roads, and also on track.

What I like
The different modes that affects how the car performs.

What I do not like
May not be a need for most drivers.
