DIY Autotune Megasquirt Plug and Play for 90-93 Miata $400
This is a first gen unit. It has fewer than 100 miles on it, seriously. It comes with the ECU and a new intake air temperature sensor.
As the name implies, installation is pretty easy. You plug it in just like the factory ECU, and then you run a vacuum line to the ECU from the intake manifold (it uses a built-in MAP sensor), and install an intake air temperature sensor (included).
The unit is kind of like this one: http://www.diyautotune.com/catalog/m...ans-p-500.html, only that is an example of the newer generation. The one I have for sale is essentially, only it's the older version. It has a tune on it for a boosted 1.6. I don't have the serial data cable (which you can get at Fry's) or the CD, but it's my understanding that the software is free on the interwebz. Other than that, I don't really know a lot about this. I bought this ECU and installed it only to find that my tuner doesn't tune Megasquirt. So I got an AEM EMS and the MS has sat on the shelf for a while.
$400.
