Is this roadster building lark starting to keep you awake at night! questions about carbs at 3.25am
Basically when running a megajolt it will run a preset ammount of ignition advance at certain rpm this is known as running in 2d mode
With a tps the (throttle position sensor) the megajolt will know how far open the throttle is and change the advance to suit the current throttle position/rpm, this is 3d mode
Definately worth using carbs with tps
You will also need an filter and base plate
