Hey man what are the benefits of running something like this and what all needs to be done? Reason I ask is because I have heard of the Megasquirt several times but never really understood what it does and is. Like I have no idea how to even use something like this. Do you run it separate of your trucks ECM or in conjunction with it? Please school me lol. Also GLWTS im sure someone here can put it to good use.

Yes, you run it seperate. And you can put it in anything. My truck runs on an msII. no stupid software to get raped on. This is the most advance unit they have which was going to be my new upgrade when I moved to texas.

I was going to put this on my 03 but decided not to go any farther with the truck. The next plan was for my 70K20 turbo lsx swap, but this thing is way more than what I need for that. What are you going to do with your MSII? Does it control your coils?

What sensors does this plug into. If you were gonna run a non-electronic trans would you even need any part of the stock pcm/harness?

Some friends of mine are thinking about an ls swap project car and this might be an option. I'd like to learn the MS too.
