Who all is using Evans Coolant?
I'm not running Evans since my car has inadequate cooling (525mm radiator,
AC, 2.0L 8V and a bunch of other heavy stuff that I appreciate) and Evans
has lower heat transfer capability. It may be good at eliminating hot spots
in the head, but the overall heat capacity and heat transfer capability is
lower than a thin antifreeze/water mix.
Anyway, nobody believes me when I say your engine should be running about 45
degrees advance while cruising down the highway. 32 or there abouts at WOT
at 3000 RPM and above. (None-turbo that is!!!).
This is the factory map for an 86-88 Audi 10V, 2.2L 5 cyl turbo engine. The
combustion chambers and piston crowns are the same as any 8V with variations
only in CR.
If you have programmable ignition then this would be a good starting point.
If your engine's NA then chop off anything above 1.01 bar.
This map is virtually what I've been running with a 10:1 CR engine in the NA
range.

As an additional note, I'd like to point out that if you're running a forced
induction engine it's almost impossible to run too much advance under boost
with 93 octane. Max power is attained just short of pinging in this
situation.
With a normally aspirated engine, especially a lower CR engine like the JH,
you can advance the ignition past the point of maximum power without
pinging.
Course it will feel damn peppy at lower revs, but max power can suffer.
Both NGP Racing and TT have told me that best ignition timing for an 8V is
around 32 degrees at WOT for an NA engine which is pretty much what the
above map shows at 1.0 bar absolute pressure.
Last point. Higher CR obviously means less advance for maximum power for a
given octane rating.

I'm running Evans. I put it in when the system was completely empty during
my rebuild. I have an extra gallon sitting around at $25.00/gal.
I did not put in a special metal gasket, I am using the OEM from TT.
I ripped out the entire CIS-E system including the knock box and computer
and distributor and replaced it with a Electromotive TEC II.
I am still running normally aspirated with no forced induction.
I have an 8x8 grid for timing advance based on MAP and RPM's
