The 123ALFA-4-R-V is identical to the 123ALFA-4-R but offers vacuum-advance too.
The unit offers a total of 16 advance-curves to be selected by the end-user.
It has advance-curves for the Giulia Nova, Spider & Bertone 2000, the Duetto and many others. There are also a couple of special curves, as used by well respected tuners.
Frequent comment : my engine runs as never before !!
