Does diy sell the board seperately? I used to get them from Glenn's Garage (before he went under), but I didn't think diy sell them.

the diypnp is cheap, and you have to build it yourself...


sometimes if you ask nicely.

Thanks.

Wait what? I thought I had it all figured out.. So what's the difference between this DIYPNP and the MS3X? Looks like they support many of the same features and are a similar price. $425 for the DIYPNP and $455 for the MS3 + MS3X expansion card.

DIYPNP cannot be upgraded to MS3, so forget about it and get the MS3/MS3X combo. Anything else and you'll regret it at some point.

Im with frank. I suggest the diypnp when ms3 is not on the table. Just do it ill walk u through it and you'll be awesome like me frank shueind and y8s.

I need to load the lastest firnware to try the new idle code.


And now u can get a vvt head and control it...

Well....

The DIYPnP is based on the MS2 CPU (technically the MicroSquirt module, but that unit is based on the MS2). So none of the cool new whiz-bang features of the MS3 will run on it.

Of course, the DIYPnP is plug-n-play, whereas an MS3 build is going to use the horrid old DB37 connectors, and whoever decided that those were suitable for use in an automotive ECU should be slathered in honey and slowly lowered feet-first into a pit filled with hungry Chihuahua puppies. So you'll have to build an external harness to plug it into the car (not hard to do, just more tedious soldering.)

The MS3 + MS3X will run with fully-sequential injection and ignition right out of the box. The DIYPnP can optionally be upgraded to support this.


All in all, the two systems are pretty similar in terms of capabilities. If you want the true plug-n-play experience, get the DIYPnP. If you have an '01 or later engine, get the MS3.

As for harness see the diybob thread I made in the diyautotune section. Or see what frank did.

If you like to tinker, have latest and greatest, or care about future upgrades. Ms3.

If you just want your **** to run really well, and forget about it after dialed, diypnp.

I love upgrading firmware, and tweeking, plus im excited about ms3 potential

Thanks again everybody! DIYPNP sounds good, but I've got a hard-on for MS3X now. I'm getting Maximum Boost & cash for the MS3X for xmas, so I'll have 3-4 months to build, install, set up and run MS3X before bootcamp, after that comes the boost (once I have time).

Edit:
The 1st and 3rd line pretty much describe why I'm getting MS3X

Isn't that what I'm doing? MS3X right?

Not true.

My mod released just recently for ms2 added a fair bit more memory from the flash. Ms2 hadn't been maxed out at all.

I'd agree that ms3 is better, but for most needs, a DIYPNP is more than suitable.

connector inside the case instead of the ridiculous DB37's and a bunch of wiring.

I guess the DB37's are fragile and should be avoided? I think this will only make sense when get done building the thing.

Techsalvager

its a mess with the wiring harness adapter. If I were to do it again I would place the ms2 into the stock ecu casing instead and put the ecu connector directly to it instead of the db37.

Also I would keep the map sensor in the engine bay instead.

heres part of the mess I have with the db37 to stock ecu connector adapter I made

Damn. That looks like something I'd like to avoid, how do I do this?

the way frank did it eliminates all the wiring outside the box.
