It's a bare circuit board and you have to solder in every resistor, etc. They include every part in clearly labeled baggies for you to build a fully featured board. You can choose not to populate every single circuit on the board if you know your vehicle won't need it (I believe there was only one circuit that I didn't bother with because I knew it didn't apply to my car, but I built everything else just in case I make future modifications).
The circuit board is clearly labeled with the resistor/capacitor numbers and all you have to do is bend the legs and solder them in.
There are two circuit boards, the main board and a second board with the vehicle ECU connector on it which is then soldered to the main board by the jumper wires. There are instructions online for all of the vehicles they support which tell you where to solder the jumper wires so that your car's existing wiring will be properly connected to the circuit board.
All in all it took me a solid weekend before I was ready to fire the car for the first time. But with the base map loaded it fired up on the first crank
Thats something I've always wanted to do. One of my large goals I had for the Focus was ITBs, which would require a conversion to speed-density, and Megasquirt was looking like the best option for that. Shame too, since the Focus ECU with SCT was pretty awesome in itself.
I had my Paypal account primed and ready to buy a set of Jenvey ITBs through a group buy but chickened out at the last minute.
At the time the Miata was my only vehicle (I have a Jeep doing daily duty now) and the thought of not having any vehicle at all for an extended period of time while I tried to figure out the ITB setup, and losing the supercharger power, made me decide against it. I live in Puerto Rico and don't speak enough spanish to take advantage of the tuning culture down here so getting parts and assistance is difficult.
i spoke with B&G when they were in seattle about this, and last i heard it was still only running with wall-power. the trick in controlling diesel injectors is the power required to make the things pop, and i have my doubts that thatll get sorted anytime soon. theres also a few things you need to know flow-wise about each injector in order to make things work properly/smoothly.
the circuit design required is also pretty intense, and a lot of care has to be taken to avoid noise... but who knows, maybe theyll surprise us. it would be fantastic if they did come out with something though
/ms fanboi, since the "early" days
Yep, it would have been my first time tuning standalone and my first time working with ITBs. I figured it was going to be a MASSIVE headache and wisely decided to stay away... for now.
I would still like to build an ITB car in the future now that I have some experience
I'll be building myself a MS system once I get going on my mk3 build, and I cant wait to get into it, but it's a ways out still
One thing to note with assembling boards like this is that you need a decent soldering iron / station. You don't want to attempt this with a $5 soldering iron with a tip the size of a pencil eraser. You need something that can maintain a set temp, and that has a small tip for working with small components

I soooo want to give the Fiat 126 the MSnS treatment. And at the same time I'd love to go the Big Carb route. I guess at the end both will cost me the same, but a small two-cylinder 80ies Fiat from Poland with electronic injection would be amazing
most of the problems i see with boards themselves are due to sloppy assembly, or improper installation.
its also important to note that if you dont know where i wire goes... check the manual before connecting it!
I tried to word what I typed in objective way, as I figured someone would disagree with me, and really at the end of the day they will both get the job done... I went vems mostly because one of the owners lives about a hour from me, and has been nothing but helpful and does dyno tuning in house. kinda nice to have the guy that designed the system's phone number.

I only used megasquirt once for a VW about 10 years ago. I built an old school bread board supporting 8 x 8 windows of resolution for the fueling, and an MSD box for the ignition.
A lot of fun, but I'm OCD when it comes to 'optimizing', so I found myself saving files for different mods, elevations, weather, octane of gas, etc.
It got silly after awhile...
Nowadays MS3 has full VVT and knock support. I've built one for my vr swap mk2, I just have to get the damn thing back together.
