Bought the MS unit from Reverant here on the board, supreme quality and customer support. I plugged it in once just to find out that there are some other things on the car I need to address. This unit is a new as can be, other than 1 plug in. This is one of the best engine management systems you can buy for a miata. Its set up for my 265 injectors on a stock 92. Any questions just PM me, I paid 860.00$ shipped plus the cable for computer hook up (I will include this)
Price: 750.00$ shipped

The ECU comes with a basemap, and on most ocassions only requires the fuel table to be tuned. This can be done through TunerStudio, using autotune (available on the registered version). This makes it very easy to tune.
