Miata Turbo Forum - Boost cars, acquire cats.

VVTuner is a little black box that will control the variable valve timing on the '01-'05 Miatas. It also translates the crankshaft and camshaft sensor readings into NA-style signals, making VVT head swaps into a MSPNP-equipped NA Miata a breeze. Currently they are available as assembled units, with unassembled kits to follow. (Had a bit of a technical update that wasn't the most assembly-friendly; we've put it in the unassembled units, but kits will get a new, easier to build board.) Check them out at these links:
