It's spoken of as the Audi timing map on this page.

Use "cut" in your search of the page and you will find it descibed for
the HT motor which is the 1985 golf gti / jetta gli

Q:   How can I get more power out my VW?
A:   Buy an SLC :->. It's an FAQ that's worthy of a book, and that's
     probably where you should start. Here are a couple of old known
     one liners which are easy & relatively inexpensive (mostly for
     North America, Europeans usually have less luxurious but faster
     cars):
     
    In general:         Reduce the exhaust backpressure (performance
exhaust)
                        Advance the timing (recurved distributors...)
                        Improve breathability (K&N Filtercharger)
                        Add a hotter cam
                        Enlarge the engine (change head, pistons, etc)
                        Replace the engine with a more powerful one :-)

     83-84? GTI:  Change throttle body.
     84 Scirocco (US):  For the JH 1.8 big-valve engine.
           Use a dual-outlet exhaust manifold from any early car
           up to '81, get the short TT's downpipe (retain cat)
           for 10 hp, with a 17% gain at 4200 rpm and more torque
           Optionally: replace exhaust system from the cat back
           (US$150) & factory VW g-grind camshaft (Autotech, $99)
     Fox:    Remove exhaust restrictor
     90-92 Passat:  Remove air-intake restrictor, APS Chip, cam
           APS chip for automatics that is supposed to do wonders 
           for low end and shift points. 
           Applicable to all cars with 9A engine (inc. 16V GLI).
     85 GTI:    Change ignition map by cutting wire #11?? on the ECU.
     85-87 GTI:    KE-Jetronics: Advance ignition 12 degr/until knock
           for more low end (5-8 Hp gain).
