Yesterday I had gone for a ride, a fairly long one with nice straight roads so tested the top speed. And I now know what the speed limiter is and how does it work. And I thought of a way to remove it.
The speed limiter is very real for the Duke 200s, this is for the people who think how could this be true. It is.
How it works is, as you reach 136 kmph the ECU then switches the ignition off. Then once you climb down to 135, it switches it on again. Due to this, your speed CAN increase to 137 and then drop down to 133-134. Then as the throttle is fully open, you again gain speed to 136 and it happens again. Due to the ignition kill, people have felt the sudden braking, which is engine braking.
Now, how to remove it? Easy I guess. As the older lot D200s don't have them, just find a friend who has the older model one and get his map flashed onto your ECU, it might take sometime for you to get use to that map but its ok. BUT I suggest this to someone who is looking for speed and doesn't mind a Kiirus remap or RD Piggy Back ECU. It would make more sense in getting the older map and asking Kiirus to change the fueling on that map.
I will be going in for service soon, will talk to the SVC guys maybe I can make some jugaad there for the map change.
