Technical Help



Advance units are parts, which contain certain characteristics of change the moment of ignition relative to engine speed. A must in 4 strokes and an option for 2-strokes. On 2 strokes however often the expense will not be in relation to the effect and at any rate advance curves are no wonder cure for old engines and do not tickle more HP out of them. Still, there is some sort of advance in 2 strokes also. See info here

Our offered systems (4strokes) contain an advance characteristic that is the result of our prooven experience. All those curves have been made for unmodified, standard engines and are not aimed at tuning.

Though our advance units have (for reasons of economy) more than one curve inside, only the curve(s) described in the installation notes have been tested for the material refered to. We know that the curves cited work with the engines in question. We can not give any other, supplementary recommendations.


For 4-stroke systems with external sensor we offer to implement advance curves designed by the customer. We guarantee that the curves change timing as stipulated, but we do not guarantie that the engine will like those curves. This is alone in the responsibility of the customer.
