Why pick the MVT Digital Direct?The MVT Digital Direct is a digital internal rotor ignition. The ignition timing varies depending on engine speed to achieve maximum power. Ignition timing controlled by a CDI unit (included).

A special feature of the MVT DD is the 12 Volt – 55 Watt connection for light (or electric water pump). You can replace your original ignition with this performance enhancing internal rotor ignition and still power all the on-board electronics / vehicle lighting. The lightweight inner rotor makes the engine much more agile and produces more power over a wider rpm range.

How to set up a MVT DD ignition?First remove the original ignition and install the MVT Digital Direct ignition correctly. Do not tighten screws on the stator and rotor until the ignition is set up and adjusted properly.It is best to use a micrometer / ignition dial gauge and follow the guidelines: 0.4 mm before OMT for original stroke and 0.35 mm for long stroke.Then connect the ignition to the wiring harness (see instructions).For even more power, we recommend using an MVT Eprom module with pre-programmed ignition curves.

We also recommend the use of a racing spark plug.
