Re: [TECH] 2.0 16v into an 81 "S"

Jason,

I haven't run a Motronic set up with my engine. I just ran the stock 16V
Scirocco injection system with a Tectonics Tuning fuel enrichment module. It
ran nice and fast with that set-up.

You can find out more about the necessities of converting to Motronic on the
scirocco.org website under the Tech Procedures. Brett put it together with
all the instructions you need.

Good Luck -- Craig
