Drivetrain Any knowledge on the AEM Water/Meth System?
I have not, only boost. since you can adjust it I have not found it to be detrimental to performance since the car's suppose to be pro tuned with it. If it's properly tuned you'll gain a healthy chunk of torque and some HP. You're able to lean out fueling a bit and start advancing more timing. This all relative to where and when the AEM controller is set to come on.

Old post but question about boost only meth kit. So the DME sees rich from O2 readings (when meth injected) wants to respond my leaning but gets confused b/c it knows how much fuel its injecting plus other inputs like load/boost /RPM'S thus it retards timing as it's "linked" to fuel delivery?? If it sees rich should it not advance timing?
I know I don't fully understand so input appreciated before I buy. Could use extra $800.00
Since a tuned Mini really only needs meth under load aka boost, why is a boost only system inferior? Lean under mild load results in more power and rich under higher load to thwart detonation and cool charge, yes? I guess a custom tune would deal with this.
Is not a IDC system superior only if you want spray all the time, which I do not? Seems like a Aquamist 4 is $1200 w/ tank and AEM is $389 w/tank.

Im not a subject matter expert when it comes to your assessment, but I will tell you that running Boost injected W/M has positive effects. Yes I know the Aquamist is top notch, I do not deny that, Wish I had the cash to drop on a $1000 system, tank excluded. But hey, I wanted the cooling benefits and the increased octane, and had a budget. Since my Snow Performance Stage II install, while running a 315cc/min Nozzel progressively starting at about 7-8psi, and hitting full flow at 12psi, I have logged a difference of about 3-4* + timing. Without the kit, running the JB+ I would only see 6* top. I have now seen as high as 9* very consistant. So, to your question of would the DME pull timing, I dont think it does. I consistantly see the instant drop at WOT, pump is pulsing the W/M, and timiing climbs 2,3,4,5,6 and up. Thats monitored by both Dash Command and BMS CAN Tool.
Hope this helps, if not hope I learn something new today

The AEM 3350 can run either (but not both???) IDC and/or MAP sensing as I'm finding out. The directions are not clear if one can only choose 1 signal source.
The issue is they have no tech support and one needs to install solo. In reading the instructions, it does not look terrible. Has anyone installed the AEM 3350/3351/3352 using IDC and factory MAP sensor? Just a couple of wire color codes and DIP switch settings and the rest is straightforward. If I were rich the aquamist and an installer would be my answer.

One thing that is absolutely critical with the Aquamist systems and its spelled out on the box and on their site never ever ever use methanol that's contaminated with hydrocarbons boy.
I'm now learning that the hard way just a shame they didn't use a rubber that was more forgiving,
BE WARNED!

I installed AEM in my 06 STi, it was generally trouble free. I did have a couple times where for some reason if I used my windshield or IC sprayer the voltage drop/spike would confuse the controller and it would stick on. Because of this I ordered their failsafe kit which looked promising. Unfortunately, it was assembled incorrectly from the factory, and once I finally did get it working it only lasted about a month or two before the controller started failing more frequently. When it works, it's awesome. The pump they use is the same as other companies like SnowPerformance and DevilsOwn. I'll be trying the V2 controller in a couple weeks, hopefully that'll fix the issues I'm having. As of now, the STi is tuned aggressively for no water meth injection and the injection only happens at 12 psi+.
If looking to save money you can go the HFS-2 route as well. It's not that much over the AEM (IIRC $600 vs $400, roughly?) and you still get the improved system just not the 'fancier' controller etc as mentioned by scubbysnacks.
I was thinking about the AEM myself until I started reading into both yesterday. If you just want an occasional spray to help clean it out (also as mentioned) then sure. But if you're actually looking to do something with it the AEM seems constrained, especially when the base-model HFS isn't much more. Granted the HFS-2 doesn't come designed for the MINI but neither does the AEM. You pay more for the 3 & 4 versions for the increased capability and the model-specific build on it.
I put W/M on the 'get in a while' list due to the price, but I'm hoping it'll be worth the wait. In the meantime I'll just request a tune (once I get it) without it then get the tune updated same-stage when I put it in.

My HFS-2 has worked great for me and since I had the problem with the contaminated methanol I've discovered that the light on the on/off button goes yellow if you get a major blockage. So while your driving you can actually tell if there's a problem and back off, if you've hooked up the fail safe it may automatically dump boost but I don't have that feature setup so don't know.
I've had a number of decussions about my front mount using the washer tank on this forum and enquires by PM this has also worked great for me. Some have suggested its not safe but I'm sure other W/M injection systems have been setup on different makes of cars the same way without drama.
I'm guessing in some states of North America during winter a similar concentration on methanol is in the windscreen solution sold in stores.

I would like to make a couple comments about the AquaMist cost versus the others on the market, this discussion took place before on the AquaMist Forum in the UK, and in the end the AquaMist is on par with anyother system out there when you look at the feature set and included hardware:

I went the route originally of a different system (in my case CoolingMist), and I was never happy with it, and it was NOT Injector Duty Cycle controlled and worked for ****, I was able to get Howerton to sell me a kit without the pump, to save on a part I already owned. In the end I ended up with a HFS-3 kit and I HAVE NEVER LOOKED BACK.
As to getting cheap Meth/Water; during winter I have found a little trick:

http://www.pepboys.com/product/detai...d_washer_fluid
This is more than 30% Methanol for a little over 4$ a gallon
MSDS Sheet: Link
You can have it shipped to the store (your local) and not pay shipping.
Also TruValue will ship to store: http://www.truevalue.com/product/De-...-Gal/40552.uts

WHY? Because maybe they do not have access to M1 locally and you have have to buy M1 in 5 Gallon jugs (at least locally for me). Also I would love to know where you are getting it for that price my best locally is 38$ with tax for 5 gallons!
Found a local speed shop that sells VP M1 @ $4 per gallon. Got 5 gallons today for $20. They sell as much or as little as you want. I get 5 gallons as it last me about 3 tank fills.
I actually am not spraying that much. Running the .8 jet and I need to fill up every 4-5 gas fill ups. My tank meth holds about 2.5 gallons. With one of the maps of my tune they suggest 500cc of meth which is a 1.0 jet. I thought that was a lot but Jeff from Howerton said it's not a crazy amount. I personally thought that was ALOT!!

I too get about 6 months (6000 miles) out of 5 gallons.
