Want to replace your 1990-2000 Miata engine or head with a newer 2001-2005 model with VVT
The VVTuner system from DIYAutoTune is a black box that controls the variable valve timing on 2001-2005 MX-5 Miata engines. This computer 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 get the most out of your variable valve timing.
Uses Innovate-style tuning cable, sold separately. Includes a solder cup DB15 connector for making your own harness; 18″ pigtail harnesses are also available, with longer harnesses in the works.
