TS spark advance points

[David Masters <david@domain.elided>]

Fellow Alfisti,

Mattias was asking for ignition curves for his hybrid Twin Spark,
and I have found these figures in the various factory manuals I
have.  Others may care to comment.

On a 2litre  GTV:
Contact Gap	.35mm on most engines, .40mm on the Marelli dizzy
Dwell angle	62 degrees (Bosch), 55 degrees (Marelli) 57
degrees (Ducellier)

The 1800cc engines use:
Fixed advance, 7 degrees, the turbo uses 10.
Maximum advance, 34 degrees or 38 degrees at 5400 and 5100
respectfully.

The 2litre TS uses
Fixed 10 degrees, with no maximum listed.

The manual does include full listing of the rise to about
3000rpm, but the distributors are all for the the 1800 cc
engines.  I don't think it helps this discussion.

Best of Luck,

Cheers,
david
