Vintage Volvo (b16,18,20) DSM CAS adapter

This adapter allows you to run a Mitsubishi cam angle sensor in place of a cam driven distributor on B20,18,16.  You will also need a CAS off a 89-92 mitsubishi eclipse with a 4g63 and some form of a programmable EMS to set this up.

Taking the crank signal from the aux shaft is beneficial since you now have a cam reference and can run a sequential injection setup.  It also is much more stable than a crank trigger setup in Mega Squirt.
