Thought it was a good touch.

So before I start tuning for methanol injection, I'd like to make sure the damn thing is doing what I expect it to. Quite possibly the best solution for this is the AEM Monitor system.

AEM Water Methanol FAILSAFE device - AEM part # 30-3020 MSRP 263.83

This was my choice because I'm using the AEM progressive meth system. I want to control when it comes on and I want to know how much is spraying during my power-band.

Comfortable Keyboard not included.




Looks good on my desk, let's see how it looks in my car.

Wiring:

• Constant power
• Ignition power
• Ground
• Fail communication wire to my meth controller
• Pump signal wire
• Illumination
• Harness to flow sensor
• USB cable for communication to laptop software

If you've followed my thread so far, you'd know that I ran my pump and tank from the back of the car. This allowed me to simply tap the meth line under my carpet instead of installing it in the bay. This is a major plus for me for a couple of reasons - I like my engine bay clean, I don't have to run another wire through my firewall and the sensor is not exposed to harsh engine bay conditions.

I have absolutely run out of places for gauges and I really dislike the idea of removing a vent for a gauge but I had to sacrifice for now



Gauge looks great. The software allows you to control the gauge color, needle intensity, warning method (needle flashing, backlight flashing, or both and how fast they flash). Pretty cool.



So the software is designed to monitor your system in working order, then set parameters in which it will send you a warning. The gauge harness also has a couple of output wires to trigger different functions - Warning lights, Map changes, Sound your horn, lock your doors.. whatever. It's two wires with controllable polarity good job AEM.

As you begin to drive, you will see your injection properties in yellow dots. To the right you will see a loading bar. Once you drive hit boost enough times it will go to the 100% mark and you can click "Auto Set Limits". This will create warning limits based on how the system has behaved under working conditions. It's always been a little too tight for my liking and will trigger all the time, but maybe that's due to how little I drove it under normal conditions before setting it. So I set mine manually.



With my setup, it will start spraying before the monitor will register anything. I think this is due to the fact that I'm really not running much methanol.

After running through a tank of meth and refilling it, I could not get it to spray again. This is very likely due to the orientation of my pump. I mounted it right side up, next to my tank. The inlet of the tank should be lower than the outlet of the fluid tank. I might have a bum pump but I'll flip it over before I draw any conclusions. GOOD THING I INSTALLED THIS SYSTEM BEFORE TUNING

MMMmmmmmMMMmm. Look what just showed up today...

Bosch valve leaking. Leaking bad. Anything else trying to slow down my spool time? Damn. Picking up a new valve today.

New Valve acquired:

Synapse Engineering
Synchronic DV Replacement Kit for Bosch BPV
Manufacturer: Porsche
Product ID: DV001A.010

You might call this the not---------around solution to diverter valves.





First thoughts:

Awesome construction, nice and small. DEATH TO THE DIAPHRAGM! Its a piston actuator! Comes with hard vacuum lines and quick connect fittings. Also includes threaded nipples for traditional vacuum lines. Some type of miniature v band looking inlet and outlet pieces, should be a direct replacement for the busted Bosch I'm running now. I'll install after work and get you fools some pictures.

Here is my busted *** Bosch.


So the project was immediately off to a start that brought me to an auto parts store. The inlet and outlet sizes of my Bosch valve were different than my Synapse.


I shot down the street and picked up 1" rubber hose to void the gap and it worked out perfectly. The 1" fit very firmly and my previous couplers fit very firmly over those. Problem solved.


The vacuum fittings are beautiful.


While I was under the hood I noticed the hard vacuum line running across the firewall was particularly ugly. The factory finish had oxidized and I didn't want to look at it anymore. I pulled it off and began to scuff it.


The usual suspects helped me with this one. Etching primer for metal and some durable flat black paint. I taped the ends to avoid the paint heating up and acting as a lubricant to my vacuum lines.



Installed vacuum line:


Quick up the skirt shot:


Review:
-------excellent. Nice firm release, no flutter with stock settings, sounds similar to the forge atmospheric valve (Which I happen to like). Clean sound and good performance. Quite enough to keep my customized license plate legitimate. During the installation I ran into a vacuum distribution block that had been leaking so I repaired it as well. Now the car starts with a nice firm -18 -19 on my vacuum gauge.

This whole thread makes me sad inside I didn't build my own turbo miata. Great stuff!

Dem768

You actually aren't the first Mazdaspeed guy to tell me something like that. Msm not the way you'd do it?

Dem768

Here are some additional pictures of when I was reinstalling my turbo after the hole.. I left these out and it really made it look like a painless process. Not everything is easy.

I'm not a patient man, but I'm not the type to rig some bullshit up. During reassembly, I noticed I was missing the gasket from turbo to down-pipe. I called dealerships for cars that came with a similar gasket, I called friends of mine who had turbo setups in the past.. nothing. Sadlife.

Being the crafty type- I went to ACE hardware and picked up a sheet of aluminum. Rather thick but a soft metal. I traced out my DP and started to cut the aluminum. After i had the shape cut I took a block sander with some 600 grit sandpaper and blocked it flat. Perfectly flat.


Didn't come out too bad! I hope this will do the job because it's a bitch to remove the DP on the BEGi setup. At one point, I was required to cut a 13mm open ended wrench in half. I went and bought a duralast wrench because I couldn't bare the thought of taking a cut off wheel to my precious snap on


There we have it. As you can see, I've wrapped the stainless lines with rubber hose this time around just to be safe.

Dem768

Went out and had a buddy drive my car next to us.. First time I've seen it driving. The bitch looks real good.


Video.. quick but fun.

That video camera makes your headlights look blue.

I like the write-ups. That's a good looking car.
