It's all THT, which isn't bad but there's a few spots it gets tight and you really need a steady hand.
I'm almost done building mine. Really hasn't been difficult at all . Almost going to be disappointed when done....I've enjoyed it
I guess it all depends on what you'd call a "steady hand" . I don't have Parkinson's or Alzheimer's or anything, but I do have to brace my hand against something to steady it if I'm welding or doing intricate work like what is needed to build an ecu project like you've pictured.
I've purchased 2 ms2's, and 1 DIYPNP kit from DIYautotune over the years dating back to 2006. The first time I saw what came in the box back then, I sent it back, thinking that it was too complicated. I built a DIY PNP kit for the red car when I planned to turbocharge the 4 banger, but sold that off after completing it, when I switched engines over to the 2v4.6.
I built the current MS2 for the monster several years ago sitting in my Jammie's on a Saturday morning. It's not rocket science.
Soldering a circuit board together is only slightly more difficult than painting by numbers.
I too liked the " build/test" part of the project...it's like a class science project on steroids. I found the mega-manual instructions to be 85% on point. The 15% remainder being the "optional" parts : i.e. " If you are using xxx for your ignition, don't install this, or remove that, or be sure to do this ." Some of that left me wondering if I had did it right. ( obviously, I did). If I had one wish/ concern about my decision to go this route, it would be that SOMEBODY would take the time to print a nicely done, plain English owners manual for the thing explaining every option in the build..An example of which, would be the boost mod...Somebody find a clearly defined instruction sheet detailing where to add this thing, with other potential options to use instead of having to dig through the expanse of the Internet..and copying off of a picture. The tuning part....even more so.
I shudder to think how screwed I'd be if there wasn't a Steve out there that could ride along sitting inside my computer to sort thus thing out.
For all of the capabilities of a ms3x,...they'd do themselves a greater good if they told you what you needed to do to add the necessary circuits to do the things it can, and do it in the same fashion that a "Building a Megasquirt ecu for dummies" would do. I realize that there is copious amounts of documentation out there on a lot of this,..but it may as well be written in another language...it needs to follow an ABC order to be relate able.
Somebody is gonna get rich off of this...Unfortunately, I'm the Dummy that needs the book, not the Smarty that can write it.
