Variable Advance Control Units??

[yorkie]

Has anyone used Variable Advance Control Units on their SS engines? Are they the same as the Monster ones i.e:

1.1 - Improves low rev output. (09098)
2.4 - Improves high rev output. (09099)
3.0 - High revs race engines. (09117)

Cheers.

Yorkie.

I tried the 3.0 on my 674 DD bike last year. It altered the power curve slightly, but not 200 quids worth.

Probably works best on a sorted 900......
