Default What's the difference between mspnp and msI 3.0?

So besides of being like $300 more and being a plug&play instead of wiring your own. What's the difference? Cold weather is coming and since my car goes to sleep I think I'm going to change it's brain from my shitty link to ms. I just wanna know the differnces and if it's worth the extra mula

The MSPNP is a MS1 V3.57 (basically a machine assembled V3.0) with an adapter board and all the circuits needed to control the Miata's inputs and outputs.

I suppose one advantage of the MSPnP is that you could get a little more support directly from DIY. It's also slightly easier to wire, since you don't have to run a line to the fuel pump. However I don't think it comes with the Hires code yet, and Joe's spark output is safer than the one on the MSPnP.

If you want to live on the edge...the DIYPnP has more potential than the standard MS-I or MSPnP.

Functionally, the MSPnP is very similar to a regular DIY 3.0 MS1.

Both use the MS1 CPU. The PnP ships with the same MSnS-Extra code that most of us use, and is capable of running Hi-Rez code. The PnP, as Matt points out, is based on the rev 3.57 PCA, which is functionally similar to the rev 3.0 board; the differences between the two are principally to reduce parts count and accommodate automated surface-mount assembly.

In the PnP, the functions that we typically build up in the proto area pr with wires on the backside (second trigger input, spark output drivers, EBC, A/C, etc) are contained on the daughterboard which houses the stock ECU connector.

The big difference, frankly, is exactly what it appears to be. With the PnP, you don't have to build it, do any mods, or do any wiring.

Yep. The big difference here is that the new unit is based upon the MicroSquirt Module, which is basically an MS2 CPU on a fancy daughterboard. So it has all the advantages of a regular MS2, such as enhanced injector resolution, and the ability to run fully sequential. With the DIYPnP, some mods are still required, of course, though it has the advantage of being plug-n-play from the car's standpoint once it's all built.

If you want to save a little coin and do some work yourself, the featureset of the MS2 based DIYPNP is superior to MS1.

build one youself, or have braineack build you one. You can get the same product from brain as you will with the mspnp.

technically it would be the same, but the tach input circuit would be different iirc.

I'm not totally sure what you're asking (english ************, do you speak it?), but the DIYPNP is the easiest version of MS to build. I mean, *I* did it.

The NA version of the DIYPNP build is actually easy as fawk. Way, way easier than building a MS1 or MS2. It's just a bunch of soldering. With a pinout in-hand, I could build it in an hour.

And some of the mods while schematically identical, will go to different pins on the CPU.
