You can just set it and leave it, using the CAS on the back of the engine's head (firewall side). You just need a timing light, and to make it easier, a buddy to help you.

But a lot of people (including me) recommend going with a Megasquirt. If you go this route it is recommended that you install the megasquirt first and get it running well on a stock setup. Then when you install all your aftermarket parts you only have to make some adjustments to the computer before it's drivable.

How painful is that install and first tune?

and where is the best place to buy one and at what price?

I would suggest you go here: http://www.miataturbo.net/forumdisplay.php?f=18 and read a lot.

Install can be as easy as unplugging your old ECU, plugging in Megasquirt, plugging in a vacuum source, and hooking up a COM->USB cable, also you need to install in IAT sensor, so you will need a bung to plug that into (usually TB elbow). Then run the wires according to the install dock (usually involves splicing them into 2 wires already on the car).

Then from there you can load a base map via a computer (usually works fairly well on a stock miata) to get you started.

You can usually pick up a used one FS in the classifieds, either here or at miataturbo.net. Braineak also builds them (MF-Brain on here) and sells them. I had him build mine and it was great.

For a stock car you can probably use Autotune to even out the map pretty well.

also I was wondering if I was using this would I still need to use the fmu that I got with my kit ?I was hoping not to have to use that and make the install as easy as possible.

You would not need a FMU if you use this.

As for the info about the MS, I can't find Brain's thread where he sells them so IDK if he is still doing it or not.

what about my injectors do u think the 265cc's will be enough with out the fmu ?

FRT_Fun

Depends on how much power you intend to make. I don't know what the expected power is on that kit. My stock injectors worked fine with 6psi on the FMII turbo kit. I find it hard to believe you would make more power than that.

k1e1v1i1n

The kit runs at 10 psi, but im trying to find an 8 psi pully. Im hoping to make 150-175 rwhp

FRT_Fun

Well psi is relative obviously, but the rwhp numbers you can actually work with.

There is a really nice post that sums up a lot of the information you are going to need: http://www.miataturbo.net/showthread.php?t=4288

I know it's a lot to read, but worth every second reading it. Here is a quote from it to answer your above post:

So I'm assuming you have a light purple ones, which should give you enough fuel to reach your goal, plus some head room.
