Just installed the basic AEM V2 WMI system and ran some 3-4 gear logs. I gotta say its pretty remarkable to see the IATs drop so dramatically as soon as the WM spray starts. Check out a couple of the logs for yourself but my preliminary observations are:

- dramatic reduction in IATs correlating to start of WM injection (start at 6 psi and end at 17).
- no timing getting pulled....zero...right up to 6500 in 4th.
- no knock....zero

Car particulars include:
- BM3 Stg 2 93
- Shell V-Power 93
- Snow Boost Juice (50/50)
- mid-size AEM nozzle
- EVO 2 Comp FMIC
- Akra 300 cell DP

I am not tuning for the meth, so no failsafe system installed. Like I mentioned, its a basic, no frills install. I'm primarily looking to keep IATs in check for open track lapping during summer months, but the additional benefits are welcome (ie added octane, reduced exhaust gas temps, etc). Ive read that WMI can also help to keep the engine oil and water temps down. if so, that would be super COOL....right ? I might even flash the BM3 race gas OTS tune and run some logs...just for kicks.
If results hold-up during actual on track testing, I'll have to believe WMI is one of the most cost effective track upgrades available for our cars. I have way less than $600 total invested for all the hardware. For track days, just need to throw a couple of gallons of Boost Juice in the trunk, and your all set. Its super easy to simply top off the meth tank after every couple of sessions. Say goodbye to expensive race gas and octane boosters...hell...the WMI works just fine with....windshield washer fluid ! Alternately, Ive read that you can throw a can or two of HEET into the meth tank along with some distilled water...and your set. Check it out.

EDIT:
Pretty hot here today so I gathered a few more test logs with the higher ambient and higher humidity levels (94 F / 45% humidity) to stress test the system / settings.
Same results...big reduction in IAT thru 3-4 pull, no knock, no timing being pulled.
Heres another log..check it out. Note that I intentionally sat idling roadside for a bit to get IATs up before starting the runs....note the temp drop thru the pull.

EDIT #2 (6/23/19):
Here's a new log from a track day at COTA with 89 degree ambients and WMI. I will include some comments in post #44 below.

This is great.

Has anyone figured out a stealth tank install on our cars, yet?

[Jkurahara]

Would love to hear more about this as I primarily docopen lapping and have similar mods. Any insight on the install?

Congrats OP. Literally been on the M2 since I recieved it. I've tried to tell people, but they just do not listen!

Not a stealth install perse, but if you have a 1gal tank, you could use the little cubby on the right side of the trunk.

Will a 1 gal tank last for a full tank of gas on a track day?

[M2C AW]

Stealth ?
Just messing around. I’ll take some real photos and post them up in a bit.

Injection rates / timing are variable, but I’ll conservatively estimate 2 maybe 3 -30 minute sessions per 1 gallon WM in our cars.
On a prior installation I used the windshield washer reservoir and topped off after every 2 sessions. Very economical when you run the numbers.

I installed the AEM reservoir that comes with the kit...1.1 gallons.

Very cool.

So, is tapping into the windshield wiper reservoir an option and just refill that between runs, vs installing a tank? And, you could still use the WW reservoir for windshield cleaning?

Yes and yes...absolutely
Issue is tho...you have to install the pump close to the reservoir in the engine Bay Area..and I couldn’t identify a suitable spot for it in this platform. It’s pretty tight up there.
I have 100% of the installation contained in the boot area including the tank, pump, and controller. Only bits leaving the boot are the 1/4” nylon meth line from the pump to the injection point, and a 5/16s nylon boost line from the controller...both terminating at the charge pipe just before the throttle body.

I’ll dig into this a little bit. The cool thing is, the windshield wiper level sensor would warn you when you’re almost out!

Yes..and so does the AEM tank. It has an integral level sensor / indicator.

[ZM2]

How does the pump know when to kick on/off, and how much meth to deliver?

The controller regulates pump start / stop via an internal MAP sensor. The user sets the desired start and stop boost pressure ( 6 and 17 psi in my case) via dials on the controller. Cool thing about the AEM pump is that it’s progressive, vs on-off only.
The rate is further controlled by the nozzle size the user selects.

Interested in checking out your set up? Might be at MSR H in couple weeks. Are you a member there?

[Nezil]

I'm working on an Aquamist setup myself, and will start a new thread on it.

I'm going to order the trunk mount 5l tank, but am strongly considering using the WW reservoir instead, or optionally.

The Aquamist system is a bit more complex in that it uses a constant pressure system (160psi) feeding a PWM valve. It also bases flow on injector duty cycle rather than boost, which should make the meth injection more aligned with fuel injection.

One of the great things about meth is that you can be quite liberal with your metering and things run fine. The Aquamist may be more refined than others, but it might also be overkill and it's certainly more expensive.

I'll make a new thread about my experiences, but there is a short lead time on getting the parts from the UK, so it's not going to be a quick project.

Not a member, but I do sign-up for DE events there when I can. I’ll be at COTA with Chin on June 22-23, if you want to come out.

I’ll look forward to your thread. I’m a major proponent of the KISS approach, which led me to the AEM system. I also considered the Snow Performance kit, but preferred the AEM controller set-up.

are AN lines necessary? as I'm line towards the snow stage 2.5 kit for the AN fittings and that epic controller.

To the OP which was closest the the intercooler on the charge pipe your boost tap or the injection nozzle?

AN lines Necessary ? No...obviously as most WMI installs don’t include them.
Beneficial ? Yes...for some users / applications. I think it comes down to whether you’re paranoid about the push connectors..or not.
When correctly installed, the nylon lines and push connectors have been shown to be very reliable.

I have the VRSF charge pipe with only one meth bung..located just UPstream of the MAP sensor. I used it for the WM, and picked-up boost pressure at the MAP sensor with a sandwich type adapter.

ok so you didn't use a pneumatic tap to the controller your tap is electronic? can you send some pics of your "sandwich type adapter"?
