Selling my trust DIYPNP as I've gone on to the world of MS3X as I am dreaming of sequential spark, among other things.
unit is Plug and Play, besides needing a wideband, vac line, and optional electronic boost control
The unit is braineack built and is quality. It is currently wired up for a 94-95 but I can modify it to work with other miatas if desired (I'd rather not, but it is doable, or I can tell you how to do it. It's quite easy if you have ANY soldering skills at all)
It has the sequential fuel board (green board in the picture)
The firmware loaded is the ms2extra 3.2.4 release
I can also change settings to match your current injectors, etc.
does NOT come with an AIT sensor as I am using that still.
$500 shipped firm. I package well and ship fast, unless wiring mods need to be done.
