VW 16V "EVO" Trigger Adapter

Sequential ignition and fueling requires a cam position signal together with a crank signal. This easy setup delivers BOTH from ONE sensor. With this adapter you may fit an EVO/4G63-compatible trigger (sourced from the original Miata). Then, choose ECU defaults for "4G63" (EVO, DSM, or Miata) and initial setup is done. Drill and tap the exhaust cam to accept mounting hardware.

Miata CAS mounted to VW 16v head with USRT adapter

A trigger drive adapter attaches to the drilled/tapped exhaust cam via supplied M8x1.25 bolt. The CAS then functions exactly as if installed on a standard vehicle. It directly reveals the cam's physically measured position just like its brother, our VW 16V "Bosch" Trigger. However, unlike that setup, it ALSO predicts where the crank should be and reports that position, too. By this means, it can do sequantial injection without adding a physical crank trigger. Whereas, the more conventional Bosch trigger requires that this second sensor setup be added.

Elite tuners run a real crank trigger together with this CAS. That way, the physically measured crank position can be compared to where it should be relative to cam position. IF the positions are different, THEN = timing belt or similar problem. Set up ECU failsafe protection. -the electronic clearance to run the interference, to put it in hip-hop terms.

Miata CAS is attached to a Volkswagen 16v like this!

Note: Any first-generation Miata (NA6 + NA8, '90 - '97) can give up the goods. They're completely interchangable. Don't forget to score the plug, too. (They differ along with the CAS between the 1.6l and 1.8l engines.)
