Manifold Vacuum Rail

 

OK! So last post was positive, engine started up, ran well and idled nicely. But that didn't last long...

While getting the tune sorted, I noticed that the vacuum readings were a little off and it turned out to be a vacuum leak due to a hose not being connected properly. Fixed the vacuum leak and then the engine didn't want to idle anymore... So I fixed the idling issue but that resulted in my brake booster not getting enough vacuum to assist the brakes ๐Ÿ™

So the real problem was the vacuum set up, I think. So I've come up with a set up that mimics a few other off-the-shelf ITB kits. Haven't had time to finish everything yet, but will post update when I get it running again and report back on the vacuum set up.

These are the push-to-connect fittings I'm using, swivel tee fittings.

20160216_17333620160216_185723
20160217_132048

Marked out the holes and drilled 11.1mm holes so that I could tap a 1/4" NPT thread.

20160221_18204720160223_140507
20160223_142052

The fittings tested fitted and measured so I could cut the hoses. The hoses need be installed in the fittings while they're out.

Also test fitted the filter backing plate, some clearance issues here...

20160305_114422

Installed a Garage Star Wiper Cowl panel, and need to make a new fuel hose because I had to go from dual to single feed fuel setup.

And finally installed and gapped the headlight covers, hate doing them so much.

Start Up!

 

This was not a smooth start up.... Ran into a few issues earlier on, car would crank over and sometimes nearly run but never more than than a fraction of a second. Went through and checked through the wiring and grounds, everything was good there, a quick visual inspection of the cam gear and cam lobes to see if they were in the right positions. And a whole bunch of things....

The ECU logs showed consistent sync loss, error no. 31. Something was wrong with the cam/crank sensors. In my particular case it was caused by the crank trigger wheel being installed backwards :P. And I actually did check it earlier on, but checked it incorrectly!

Once I flipped that trigger wheel around, it started right away! Here's a quick video of it, more to come later!

Back Home!

 

Happy day! Car has been towed back home and first thing we did was remove all the front panels ๐Ÿ™‚ Storing them in a spare bedroom for now, don't want to scratch anything during assembly.

Colour is Audi's Aviator Grey.

20150923_100837

The entire engine bay was covered in blankets during the engine install.

Hnnnnggggggggggg!!!

20150923_14115920150923_141152

Colour looks amazing in sunlight, the Audi paint code has a bit of pearl through it but can only be seen in direct sunlight.

20150923_14122020150923_141215
20150923_141210

The freshly powder coated radiator and sway-bar brackets fitted up with new bolts.

A quick mock up panel for the engine harness Deutsch bulkhead connectors.

20150923_133051

I had the front lip painted gloss black, will be interesting to see how well it holds up from all the abuse it cops ๐Ÿ˜›

Off To Body & Paint!

 

Today was a good day ๐Ÿ™‚ my Mazda was towed off to J&D Quality Smash Repairs.

20150729_145133

Everything all set aside and ready to picked up.

20150729_145212
20150729_14590420150729_145909

Looks tough without the rear bar!

20150730_08252020150730_082501

Tow drive arrived around 8.30AM and had her loaded up for a 30mins drive.

20150730_08275520150730_083226
20150730_083535

Sort of weird seeing your car get towed away, good weird though.

20150730_083932
20150730_08363620150730_084433

Once arrived at the shop, we continued removing a few more bits and pieces from the car. Things like rubber seals and everything in the door jams.

20150730_100410

Quickly cleaned up one side of the engine bay using wax & grease remover with 3M Scotch Brite pads. Cleaned up really well and gets the surface some what ready for primer and paint.

20150730_11393420150730_113942

Decided on the engine bay colour, this is Audi's Aviator Grey. Clear coats will be applied on top of this too.

20150730_114545

More updates next week!

22Jul/150

More Stripping.

 

OK another small update before everything is ready to be towed off to the panel/paint shop.

20150717_11140420150717_111351
20150722_113453

Fuel lines were disconnected and capped off, fuel rail was also removed. Wiring was also pulled back into the cabin. Engine bay starting to look really bare. Next will be engine, brake booster, clutch master and all the hard lines.

20150722_113505

Since I was sending out the headlight assemblies out for blasting and powder coating, I removed the sway bar mounts to get them done too. Involved drilled out a few spot wells but whatever. They'll be powder coated black with the other bits.

20150722_113444

Door handles, window seals and antenna were removed. Still have to remove the seals around the front windscreen, and all the trims/seals on the hardtop.

20150717_11141220150722_113425

Front and rear bars off, rear garnish and rear tail lights out too. Forgot to remove the third brake light ๐Ÿ˜›

20150721_194603
20150721_15595320150717_121927

My Nardi 330mm Deep Corn wheel arrived, also ordered an awesome wireless dongle so I can have remote boot release. I love the remote so much! Has fake wood grain, a red button and a telescopic antenna! I may ditch this kit and go with a 3/4-way kit so I can have keyless entry too.

Respray Preparations.

IMG_5752

As some of you may know, the MX-5 is booked in for a re-spray and engine bay colour change. Body will be painted factory Crystal White and the engine bay will be Battleship Grey. Now the stripping and preparations begin!

20150716_12433720150716_124341 20150714_212235

Seats were removed to make it easier to pull the dash out. Dash came out so I could pull the wiring harness completely back in to the cabin.

20150715_10533120150714_165118

Rest of the parts being stored away. The ARP CF mirrors getting sanded back and a new coat of clear too.

20150716_12430220150716_113932

Pop-up headlight assemblies will be disassembled and sand blasted, they'll be painted same colour as the engine bay.

Jass Performance Interior Light Install

 

The MX-5's interior is known for it's minimalist nature, and with that comes the poorly lit interior. Vlad from Jass Performance has come up with a neat solution and below is my installation, with a slight difference.

Jass Performance Interior Light.

visorlight00

The kit comes supplied with instructions and is plug and play.

20150707_10500420150707_10504620150707_105051

Firstly, you'll need to remove the visor and roof latch. This'll allow you to mount the light and tuck the wires away.

20150707_10544720150707_105614

The passenger and driver side lights mounted up and wires tucked away. It's a little bit tricky to do, try have someone else around to help out.

20150707_110613
20150707_11061920150707_111819

The black wire has a small ring terminal which screws into your existing courtesy light, this just allows it to turn on with the doors and still give you the ability to switch them on/off whenever you please. My install is a little different to the standard instructions, I've added a plug and soldered the red wire directly to the factory light. So please note that soldering is NOT required.

20150707_11290420150707_11301620150707_114708

Lights working.

20150707_12020420150707_120208

And a quick photo to show how much coverage it has. Photo was taken without flash and in complete darkness.

20150707_224204

Second photo below was takenย using a higher ISO setting on the camera, again no flash and in complete darkness.

Head Unit Relocation 2nd Update.

 

Received some feedback and discussion on my head-unit relocation last week, and as I often find, I decided to change it up to the better option.

Below are photos of where the head-unit was mounted, I made a custom MDF piece for that spot too.

20150611_09404220150526_110301

But it was obvious that the better position would be in the other corner of the boot, and mounted from above. Overall it looks a lot cleaner and more out of the way.

Started off by half removing some of the rear carpet, I than removed the bottom four bolts of the rear parcel shelf cover. Made it a lot easier to run the harness.

20150611_09301120150611_093014
20150611_093538

Harness fed through and the head-unit case mounted up!

20150611_09395920150611_094421

Everything mounted and connected, works just as well as before.

Head Unit Relocation IR Repeater

 

Moshi moshi.

I decided I didn't really enjoy the tablet install, so this will now be the 3rd revision of the MX-5's audio setup.

20150526_090938

Goal was to create an even simpler interior, might even delete the AFR gauge, by relocating the head unit into the boot/trunk. I still wanted to retain full audio controls as well as Bluetooth and USB connectivity. My old audio setup worked well but the sound wasn't the greatest, probably from the lack of pre-amp/equiliser control.

Although I planned to mount the head unit in the boot, I still wanted full control of the unit, this was achieved using an IR repeater. Normally used in home theatre setups. Simply have the repeater eye in the cabin, and the repeater transmitter in the boot with the head unit.

1E-1

First thing was to make up an extension harness that goes from behind the tombstone and into the boot. I used roughly 5 meters worth, and I went with something more flexible, conductor is 38/0.15 strands. And I've just terminated the ends with connectors.

20150525_17140220150525_170613
20150525_172826

Connectors....

20150526_10285320150526_103634
20150526_104350

Pictured below is the IR receiver unit, I've mounted this just above the rear view mirror. The harness was plugged up, and you can also see the little USB power adapter that's powering the IR Repeater.

20150526_092546
20150525_18040320150526_093323

This is where the head unit will be mounted in the boot. I've made a cardboard template for that little spot and will make it out of marine plywood and covered in automotive carpeting. You can also see the IR transmitter double sided tape right in front of the head unit's IR receiver, and the right angle USB extension cable.

20150526_11030120150526_112440

The completed setup, showing how much simpler it is now. The other end of the USB extension sits in between the driver and passenger seat, and the remote control has some double sided velcro to keep it easily accessible.

Automatic Windows – Testing

 

Sup everyone!

This project has been on the back burner for awhile, but finally ready for testing. Everything hasn't gone exactly to plan, so farย the circuit only works with the factory switches and not my Centre Console Delete Kit.

The plan is to make a simple plug-and-play kit that allows both windows to go up/down automatically. I realise that the JDM NA8s came with automatic driver side window from factory, and I will be making kits available for single window applications as well as both windows.

Quick demo video here:

Ignore my slow windows, the sliders need a clean ๐Ÿ˜›

One click initiates automatic up/down, clicking the switch in opposite direction stops the automatic function. Holding the switch for 2secs overrides into manual mode.

20150303_11220920150303_112423

This is the little circuit, will be cased up etc when done.
