MSM DIYPNP ECU Upgrade
 

Hello folks, I'm currently looking at a DIYPNP ND122 Megasquirt kit to upgrade my Mazdaspeed Miata ECU. Has anyone ever built one of these? I can't seem to find anything, such as a guide or tutorial. I have experience building electronics, but nothing really specific to cars/automobiles.

Anyways, any sort of help, advice, or instruction to get this done would be greatly appreciated. I've already spent what seems like forever on Google, and I've even emailed DIYAutotune. I know there are a few vendors selling a PnP solution, but I would really like to save the money and build this myself. (The only one I even considered purchasing was Dimitris MS3 PnP boards.)

The main DIYPNP build guide is here:

DIYPNP Documentation - DIYAutoTune.com

We currently don't have a specific set of install notes on the Mazdaspeed Miata.

You're better off getting their prebuilt MSPNP for the mazdaspeed. Just save yourself the trouble.
