The 123MINI-R is designed with the mini-enthusiast in mind who does not require a vacuum advance unit. It is available for the old 'pre-Aplus' Mini, but also for the Aplus engines. ( referred to as : 123MINI-R-V-A+ )
The unit is layed out in such a way, that static timing can be done on TDC, by means of the built-in LED.
The 16 curves are nicely divided over the spectrum, so that the unit lends itself perfectly for tuning.
The installion manual also offers a comprehensive list, that links a curve-setting to a particular engine.
