VVTuner

A DIYAutoTune.com exclusive! The VVTuner system was designed by Miata racer Kevin Boswell to control variable valve timing on the 2001-2005 Mazda MX5 Miata engines. Allows for closed loop control of the variable valve timing, and translates the NB sensor signals into NA style signals, making this system allow for swapping a VVT motor (or just the VVT head) into first generation Miatas.

Currently available as assembled units; kits will be added at a later date.
