So I have been working on this for a while now and it has been enjoyable. I thought I should share this info and later I will make something like a how to for this system because there isn't very many for the MSII system.

After lot of people telling me I should go with DSMlink with going standalone, I kind of took a side step and went with a less traveled route. I took the plunge and bought a MegaSquirt system. DSMlink sounded tempting because of the ease of just putting the system in and go however I checked my ECU and I have a non Eprom and not only would I have to find an ecu with an eprom I would have to go and get the DSMlink upgrade. Megasquirt so far hasn't come close to the cost of a DSMlink. However the Megasquirt need a lot of time to put together. I am going to see if I can break even by selling the MAF-T and the ECU.

For those people who don't know what a MegaSquirt is, it is a standalone ECU that you can buy as complete or as a kit to solder together.

The kit that I bought was the new Megasquirt 2 processor which has a lot more features then the original processor. The board version that I have is V3.0 There is only a handful of dsms that are running the MSII processor but the ones that have been running it have had great success and I have heard very little complaints about the system. I bought parts from DIYautotune.com. Very good people to work with.

Assembly of V3.0:

So far in the assembly, I am almost completed with the kit and just have to do the modifications to get it to work for a 4-2 CAS (miatas almost have the same cas or code). I will post pictures of what it looks like later. All the test along the way have been proving successful and megatune (software for tuning the megasquirt) is fairly user friendly.

Main reason I went with this system is the idea of building the ECU from scratch sounded fun to me. Most of the parts I have on my car have been from scratch. Also building the system would give me something to do over the winter.
