Factory Mameshiba original version is also available as a single unit.
Even if you have already installed other version of the kit, you can replace this unit by coupler-on.
Because two kinds of ignition maps that are completely different and specialized for each of the low compression stock engine and the high compression high tuned engine are made all-in-one, it is effective for the knocking avoidance in the high compression high tuned engine. And at the same time, it matches by only switching the channel at the time of the engine tuning in the future even if the present engine is stock.
In addition, in order to perform more precise ignition timing control, the latest 3-dimensional map corresponding to TPS is programmed, so the expandability is also high level.
