There are several dealers if you google megasquirt. All over ebay too. Also a list in the megamanual. My favorite here. |

I am glad that much you are clear on. It is not safe to assume anything. But it is helpful to think of it in simple terms at first. I would start with the fuel lines. You must have a return system,(there are others, but not worth mentioning), since the car wil still run carbureted with the new lines added. You can run your return line and just cap it off and leave it ending where your pressure gauge will mount. Then you can still drive while you work on other stuff. Then go about installing the various sensors. You will ruin the O2 sensor if installed but not hooked up, so leave that off until last. But you can have the bung welded in, and plug that. Then go about getting the manifold/injectors and TB worked out. This will take some time, but you can do this while still driving the car.Then you can get the ECU to hook everything up. Just think of it one step at a time. You might also want to work out your air cleaner. There are several different types, and you will want to do a bit of research to decide what you want to do with that. I would not consider building your own MS ECU. Unless you are an expert electronics guy, that is just one more thing to think about. When it doesn;t run at first, you want to be able to eliminate that as a possible cause. A good supplier will have tested the unit ahead of time with a test module. Last, you swap the manifold and install the ECU. At this point the car will no longer be drivable, so plan on a period of time when you won;t need the car. If you are dedicated, and a steady worker, you can probably get the manifold installed, pressure regulator and fuel lines hooked up in a week end, and then get the ECU wired, sensors hooked up in the following week end. If you have evenings free, you can likely get these things done in a week of evenings or so. I don;t know if you must keep this car running for work or school, but you will need alternative transportation for a while. It would be a good idea to get a substitue vehicle for at least several weeks so you don;t feel any great pressure to get things going. If you have ideas of upgrading your exhaust, you might want to think about that ahead of time, and make that change when you install your new intake. In the end, it is alot like a carb system. Spark, fuel, and air. Spark and fuel are now digitally controlled. Sam |

Quote: Thanks Matt, I already downloaded that page.
The MS-I can do ignition control, and since the hardware has been out longer, there's a few things in its bag of tricks that haven't showed up on MS-II. However, either one works for basic fuel and ignition control. Both versions are covered in the article I linked to. With the MS-I you would need MS1/Extra code, which gives it 12 x 12 tables, but not quite the same resolution.All right guys! I guess I have some reading to do! Could someone suggest what page on the MS website I should start with? Will the MS I do ignition control? Or should I consider the MS II? I'd like to look at the basic manual, but for some reason (maybe because I'm an idiot) I can't find a page for it on that website? Thanks! The basic Megasquirt manual is here: http://www.megamanual.com The MS1/Extra "sub-manual" is here: http://www.msextra.com/manuals/MS_Extra ... _Index.htm I know, it's a lot to take in at once. It's easier to split it up into separate tasks. Here's the particular areas to focus on, one step at a time: 1. Plumbing up the fuel system side of things - this is going to be about the same for any system, Megasquirt or others. 2. Ignition control, if desired. This one is pretty well documented. 3. Making a wiring harness and setting up the sensors. Megasquirt has a built in MAP sensor, so you just need four other sensors besides the ignition: TPS, two temperature sensors, and your O2 sensor. I'd also note that you'll probably want to beef up the alternator and add a few noise-reducing parts in the electrical system. 4. Getting the system tuned. |

Quote: So can you get the MSII in a complete kit, or only the partial kits I've read about, and at what prices?
I wondered how it all came together also so I PM'ed Matt Cramer since he works for DIY Autotune (an MS distributor) and he already has a Megasquirted Dart. He asked me a few questions about what I wanted to acheive and he gave me a "shopping list" to go junkyard/ebay hunting. They will even assemble many of the parts for you if you change your mind about assembling it yourself.

Thanks for all the responses guys. Lot of stuff to study and think about. Fortunately, I'm experienced in a number of areas involved here, but we'll see how it goes. Thanks again! By the way, what is the EFI332 project I've heard about? Seems to be by the same to guys who started Megasquirt. Same thing? Matt, I sent you a PM! ________ Honda RC115 |

It was an earlier, and less succesful, system that Bowling & Grippo were involved in. It wasn't as user friendly and required a lot of programming knowledge. There may have been 50 or so of these built, and I'm not sure how many of those 50 were ever used on running engines.
