VVT Controller

Ah, now it will be pretty simple to plop my recently purchased VVT-engine into my 99 and swap back to the 99 engine at any time (e.g. for inspection). ![](https://www.miataturbo.net/images/smilies/smile.gif)
I only need it to work in April so there is a lot of time for you all to figure out everything until then
(maybe even a version 1.5 til then as usual).
Having the 12x12 table inside TunerStudio would be nice, but I feel that VVT optimization would be done on a Dyno anyway (as a separate parameter), and then a separate application for a separate purpose can actually be better (separate updates when things change).
Hmm, why not also offer a VVT-solenoid pigtail for those that didn't also get the engine harness (or don't want to hack it up)?

Not needed. This is a simple, self-contained product that does only one specific job.
I'd think that you might get some interest out of the Subaru crowd if 36-2-2-2 (crank) plus twin 4-1 (cam) was supported, with dual outputs. (Subarus, being flat fours, have two intake cams, two cam sensors, and two VVT actuators. The mechanism is similar to the Mazda BP-Z3.)
I've got timing diagrams both from the factory manual and from on-car observation available if there's interest in this from the development side.

I have a random question about the VVT controller. How is the delay of timing signals from the VVT controller to MS. From what I understand the NB signals go into the VVT controller, get read and then converted to the NA CAS signals and then get fed to the MS. I am assuming that the delay of doing all that does not actually add to up and your reading the info slightly delayed?
