Hello Pe,


It is a ICU-L ignition. My MVVS26 with the ICU-L works fine and is running set to a tuned pipe(long). When I ran it on the bench, it was set for a pitts muffler(short). I also have a ICU-L for my Evolution 58, I can't change the timing..
Also I have the Evoluiton 26 and the ignition is identical to the MVVS and the timing can be changed.
The ignition on the left is the MVVS, the one on the rignt is the Evolution
