Standalone VVT controller for Mazda 01-05 MX5 Miata engine

The VVTuner system is a black box that controls the variable valve timing on 2001-2005 MX-5 Miata engines. This one also translates the NB crank and cam sensor signals into NA style signals, making it perfect for swapping the VVT head into earlier Miatas. Can be used with the MegaSquirt or on its own to custom tune your variable valve timing. Comes preloaded with base map to get started.

Uses Innovate-style tuning cable, sold separately. Includes a solder cup DB15 connector for making your own harness. 18" pigtail harnesses optional.
