    haha! There's 2 PNP Megasquirt, if you get the MSPNP then you just plug it up and it's ready to go. The DIYPNP is what I bought and you have to assemble, but it is a better ECU. The MSPNP is based on Megasquirt 1, DIYPNP is based on Megasquirt 2.

    Prototype Gear Knobs - http://omgpham.com/prototype-gear-knobs

    Been busy the last week with prototyping a few gear knobs that I hope to produce in the future. With help from a friend, these were turned manually on a lathe and made from stainless steel and Nylon with a steel insert. Threaded specifically for MX-5/Miata models.

    Will be testing them over the next couple of weeks to see how they perform. And final production units will be available in stainless steel or Delrin.

    I took some photos of the process and will update later with installed photos. Enjoy =)



    1. Bored out the centre and drilled a hole for the thread
    2. Tapering the bottom half of the gear knob
    3. Rounding/smoothing the top of the gear knob


    Completed piece with a nice smooth brushed finish.



    1. Centre drilled out and bottom tapered
    2. Turned the entire length to give it a nice clean finish
    3. Top of knob was rouned to a nice smooth finish


    Machining the steel insert that will be pushed into the nylon body, gives it added strenth.


    The completed knob and our method of "pushing" in the steel insert.

    Vented Windows - http://omgpham.com/vented-windows

    It gets damn hot inside an MX-5, daammmnnnnn hot! So I picked up some vented front quarter windows. I wanted the KG Works "winged" windows but they're about $1200.... the ones I got are the next best thing =P

    Installation was a breeze and they get a lot of air into the car, works much better than I thought. They're made from Lexan and the vents are designed for light plane air ventilation systems.



    So first thing was to remove the door card, this will reveal a few bolts that hold the the window frame. Slide the seal out to reveal two screws to completely unbolt the frame.



    The window then slides out pretty easily, rubber seal comes off too. I then cleaned it up with some warm water and soup, heaps of gunky build up.



    Slide the cleaned up seal onto my vented window, so pretty!



    With the help of some rubber lubricant, the vented window slides in very easily.


    Then repeat on the driver side, and my JDMST Supporter sticker.



    Some nice close up photo.

    nice work on the gearknobs!

    if you didnt, try freezing the metal and heating the nylon before joining them. if you can custom make one to certain dimensions i'd more then happily purchase one

    MegaSquirt DIYPNP ECU Build - http://omgpham.com/megasquirt-diypnp-ecu-build

    I've been slowly building my MegaSquirt DIYPNP ECU, just wanted to take my time so I don't screw anything up. I have configured to be run on a standard engine with MAF removed, just so I can learn how to tune the basemap. This means standard narrow-band O2 sensor, stock TPS, etc...

    All instructions can be found in the links below:
    http://www.diyautotune.com/diypnp/docs.html
    http://www.diyautotune.com/diypnp/ap...3-16b6-mt.html

    For photos of the unboxing, check my previous post here.


    This is the ECU harness connector, plugs right into the MX-5 factory harness.



    1. Resistors get soldered on first
    2. Diodes and other taller components are installed
    3. Connectors, ICs and the rest of the parts soldered


    I found this to be the hardest part of the build. Heaps of wires that need to be cut to length, stripped and tinned. This pinout will be different for each model of car, pinout can be found on the DIYAutoTune website.



    The finished ECU looking all clean =)

    Good to see someone else giving the Megasquirt variants a go. They're a nifty bit of kit for the price. Perhaps not as well equipped as some other ECUs, but still pretty damn capable for most basic applications. Definitely worth buying a wideband O2 sensor when funds permit though, since they allow a far greater range of AFR feedback and you can utilise the live tuning software within TunerStudio.
