Description mvt dd23 - Internal rotor ignition with lightMVT Digital Direct 19 internal rotor ignition with light for 2-stroke Chinese scooters (CPI / Keeway etc.)MVT Digital Direct - Top performance plus lightThe MVT Digital Direct ("MVT DD" for short) is a digital internal rotor ignition with variable ignition timing, i.e. the ignition timing changes via the CDI depending on the engine speed in order to provide maximum power at any given time. It is primarily intended for use with racing or high-end setups 70cc and higher.The main advantage of the MVT DD ignition is that it is equipped with a 12-volt 55-watt output. Unlike many other internal rotor ignitions, you can retain lighting and on-board electronics with this ignition. Performance is noticeably improved, particularly in terms of power band and responsivity.Adjusting and calibrating the MVT DD ignitionFirst remove the original ignition and install the MVT Digital Direct ignition properly. Do not tighten the stator and rotor until the ignition has been adjusted.Use a micrometer or a TDC dial gauge to set the following parameters: 0.4 mm before TDC for original stroke and 0.35 mm for long stroke.Then connect the ignition to the wiring harness so that the vehicle lighting works (see assembly instructions).If you need even more power, you can combine the ignition with the MVT Eprom Box to select the appropriate ignition curve.We recommend a racing spark plug and a carburetor with a diameter of at least 19 mm.RequirementsA micrometer for precise adjustment of the ignitionA charged 12-volt battery. We recommend this 12V - 5Ah SLA4L-BS SLA battery.Additional information:Suitable for Chinese scooters with 2-stroke engine / Minarelli replica engine such as Keeway, CPI, Sachs ...etc. Questions about the product Downloads and Media Installation guide

Notes and Safety MVT Digital DirectThe MVT Digital Direct ignition is the brand's top model, with extreme performance, agile engine and optimum response at all engine speeds thanks to a lightweight internal rotor and CDI with variable ignition timing. Bonus: the ignition has a 12V output for lights / on-board electronics!The DD internal rotor ignition has a digital CDI with variable ignition timing adjustment, i.e. the ignition timing adapts to the engine speed and is therefore ideally suited for tuned engines. In this way, you always get the best ratio between torque and maximum power, regardless of RPM.Advantages of MVT Digital DirectDigital internal rotor ignitionWith lightSimple adjustme
