Racers with high compression naturally aspirated engines or boosted engines who are looking for an alternative to boost-dependent water/methanol injection controllers have a solution in AEM's Multi-Input WMI controller. The multiple input design enables users to install AEM’s Water/Methanol Injection Kit on both high compression naturally aspirated vehicles (NA) via the MAF/IDC settings and ultra-high boost vehicles (above 40 PSI) using an external MAP sensor. The Multi-Input controller works with an external 0-5v voltage-based external MAP sensor, a frequency-based input for Injector Duty Cycle (IDC), frequency-based mass airflow (MAF), or a 0-5v voltage-based MAF. The Multi-Input controller is offered in three kits; a one-gallon tank kit with a single injector for gas engines (PN 30-3350), a tank-less kit with a single injector (PN 30-3352), and a five-gallon tank kit with two injectors (PN 30-3351) for HD high-output gasoline applications.

Water/methanol injection for gas engines is a proven means for effectively reducing engine inlet air temperatures and suppressing harmful detonation on high compression naturally aspirated (NA) race engines. This allows racers to reliably advance ignition timing—without using high-octane racing fuel—for improved power gains. AEM’s Water/Methanol Injection Systems utilize the most robust hardware combined with more advanced features than any other comparably priced water/methanol system.

AEM's Multi Input controller design enables users to install Water/Methanol Injection on high compression naturally aspirated vehicles (NA) via the MAF/IDC settings. The Multi-Input controller works with an external 0-5v voltage-based external MAP sensor, a frequency based input for Injector Duty Cycle (IDC), frequency-based mass airflow (MAF), or a 0-5v voltage-based MAF. The Multi-Input Controller is available with a 1.15-gallon tank (PN 30-3350), a five-gallon tank (PN 30-3351), and a tank-less kit (PN30-3352).

Note: FOR OPTIMUM RESULTS, ALL WATER/METHANOL INJECTION SYSTEMS AND FLOW GAUGES SHOULD BE RUN WITH AN WMI INLINE FILTER (PN 30-3003). For additional insurance against unintended flow, particularly when the pump and tank must be installed higher than the injections nozzle, we recommend adding our optional High-Flow Low-Current WMI Solenoid (PN 30-3326).

Robust, Easy to Use Controller Design
The Multi Input Kit PN 30-3350 controller design features large, turn-resistant knobs and larger numbering to easily set accurate start and full activation points, with covered status LED and test buttons for added splash resistance. A plug is integrated into the controller housing for mating to the redesigned wiring harness’s positive-lock connector, an easy-to-access integrated fuse and molded mounting tabs. Programming the Multi-Input controller for MAF, external MAP or IDC is easy; it has a plug covering the programming dipswitches and a programming legend on the back for the 0-5v and frequency based settings.

Innovative Injector Design Delivers Faster Cooling with Less Fluid Used
Our breakthrough injector design uses unique Swirl Generator Technology that improves atomization to deliver faster inlet temp cooling and uses less fluid to maintain inlet air cooling. We include three Swirl Generators that deliver 250cc, 500cc, and 1000cc of flow. The AEM V3 WMI injector is included in every AEM Water/Methanol injection kit and is a direct replacement/upgrade for the V2 injector in older systems (V3 Injector PN 30-3315).

In testing at AEM, the new V3 250cc WMI nozzle and the V2 250cc WMI nozzle both achieved a 90-degree inlet temp reduction; however, the V3 nozzle design achieved this reduction nearly 6.5 seconds faster. Consider that on an average sportsman drag car this can represent close to 40% of track time. On a road race car, applying more timing 6.5 seconds faster can mean a critical time to pass on a corner exit.

We then tested a V3 250cc injector against a V2 500cc injector to see if the larger V2 injector would improve cooling speed. The V2 500cc injector achieved nearly identical cooling speed as the V3 250cc injector, but it required almost 44% more fluid to achieve the same cooling. Less fluid used means fewer refills of your WMI tank and less money spent refilling it. Using the V2 500cc nozzle with a one-gallon tank, you will get close to 7 minutes and 50 seconds of run time at full pressure. Using the V3 250cc nozzle with a one-gallon tank, you will get 13 minutes and 30 seconds of run time at full pressure.

Heavy-Duty Waterproof High Pressure Injection Pump - Safe for Engine Bay/Frame Rail Mounting
AEM’s internally-bypassed water/methanol injection pump is waterproof and safe for mounting in loactions that are exposed the elements. It does not cycle on and off and provides quiet, smooth operation. It features robust construction including integral hose fittings, EPDM seals and a Santoprene diaphragm that provides consistent and reliable fluid delivery.

Low-Profile 1.15 Gallon Tank
AEM’s gas Water/Methanol Injection Systems are available with or without a compact 1.15 gallon tank that features an anti-starvation reservoir. A more accurate, conductive low level fluid sensor is integrated into the tank and features a positive lock connector with color-matched wires to the wiring harness. The sensor eliminates any chance of incorrect readings due to interference from debris.

Simplified Wiring
AEM’s Water/Methanol Injection kit’s wiring harness is terminated with a positive-lock connector on one end and has color-coded wires to ease installation. Both the power and ground wires for the pump are included in the harness which simplifies the wiring process and eliminates any chance of the pump accidentally activating from a short in the system. An additional wire is included for adding an optional on/off solenoid to stop fluid flow when the system is inactive. 

Integrated Boost Safe Feature
The controllers in AEM’s Water Methanol systems include an integrated “Boost Safe” output feature that monitors the entire injection system and triggers a ground signal via an output if it detects a voltage-related error (short, bad connection, broken wire, overheated pump, high or low voltage signal, etc.), allowing users to define their failsafe strategy from something as simple as flashing a warning light to more advanced strategies like pulling boost or ignition or switching fuel maps on a standalone engine management system. Combined with the integral and highly accurate conductive low-fluid switch in the tank, “Boost Safe” can also put your engine in safe mode before the system runs dry. This exclusive feature is found only on AEM Water/Methanol Injection Systems.

Revised Flow Control Strategy for More Linear Fluid Delivery
AEM’s engineers spent extensive time revamping the controller’s flow control strategy for a more linear flow output delivery. This means that the flow delivery better matches an engine’s need for water/methanol injection, which further optimizes charge air cooling and detonation control.

WATER/METHANOL INJECTION ADVANTAGES FOR GAS ENGINES:

Reduces Air Inlet Charge Temps
The term “liquid intercooling” with water/methanol injection refers to a highly atomized mist of water/methanol that is injected into the airstream and begins to evaporate. As it does, this evaporative effect reduces air charge temps by as much as 100 degrees, and delivers a more oxygen-rich air charge.

Reduces Detonation (Knock)
Water absorbs heat, and methanol is a cool burning, anti-knock rated fuel. When combined and introduced into the inlet stream, they can effectively increase your vehicle’s anti-knock index so you can reliably increase boost pressure and advance ignition timing using pump gas.

Reduces Carbon Deposits
Modern vehicles fitted with Exhaust Gas Recirculation (EGR) devices for emissions control promote heavy carbon build up inside the air intake. This carbon build-up can create ‘hot spots’ in the combustion chambers that can cause detonation. Water/methanol injection has a ‘steam cleaning’ effect that reduces this carbon build up, and in some cases can increase fuel economy.

DO NOT BUY - NOT USER FRIENDLY
Color: White
This mop has the worst design and cheaply made. I do not recommend buying it. Cons: the cord is too short; there is no place on the mop to wind up the cord when you put it away. The cord just flops all over the floor. HOW CHEAP IS IT NOT TO PUT HOOKS ON IT SO THE CORD CAN BE WOUND UP? The mop does not stand on its own. It goes straight to the floor no matter what position you put it in it will not hold an upright position. It lays in the floor. The water compartment does not come off the mop. You have to pick the whole mop up and hold it under the faucet to fill. Or lay it on the floor and get a glass of water to fill. Makes a mess. One more big gripe - THERE ARE NO SETTINGS OTHER THAN ON /OFF AND THOSE BUTTONS ARE WERID. There is no high, med, OR low setting. Lastly the mop pad in the photos was not the one it came with. It had one very thin like disposable one. PROS- NONE. I RETURNED IT .

5 month review- still a favorite!
Color: White, Color: White
I purchased this steam mop 5 months ago and it is still one of my favorite purchases. I have used it every week 1-2 times per week and it still works great! My house has wood flooring throughout, two cats and a lot of traction. I can finally relax knowing my floors are clean and sanitized! It heats up very quickly and the cord is long enough to do large sections of floor at a time. I highly recommend this purchase! Especially if you have pets or kids.

I spent the $20 I saved on stuff to make this thing functional-ish
Color: White
The only reason this is getting three stars is because I do like the ability to shut off the steam and also it puts out the perfect amount of water and cleans well. For the bad, the design is terrible in four important ways as mentioned in other reviews (which I wish I had read before purchase so my fault). 1. This thing will not stand in its own unless in a very particular position and even then a slight gust of wind sends it toppling. 2. The one hook cord storage has to be the stupidest design I have ever seen. I did buy a command hook so I could wind the cord so that takes care of that issue (other than no notch to secure the plug to the cord). 3. The cord is not long enough but again I remedied this with a 6ft extension cord though I’m sure this is probably not recommended somewhere in the instructions so I take my own risk. 4. I did not like the pad included but have a ton from my old Shark steam mop (RIP) and they work well enough with this mop so it’s not completely useless. I would not recommend this mop to anyone. It is a bit cheaper than the Shark mop I was looking to replace but wish I wouldn’t have let my cheap side win and it’s spent the extra $20 to get a mop I know I like.

Quality Knives At A Bargain Price
Size: Steel King 15Pcs 10.4"×7"×15.4"
I have had these knives for almost 18 months now and they have held up great Edge retention is fantastic, and as long as you treat them right and don't leave dried tomato sauce on them for 5 days, no rust to speak of or even any discoloring! The build is fantastic and they are well balanced. I still can't believe I got this set for the price I did. I have a collection of pocket knives, I own Japanese wet stones to sharpen and understand what 8cr13mov, s30V and 14c28n is in knife production. (It's metal alloys BTW.) Having said that, I was a bit picky in finding a knife set that was quality built, had good steel and didn't cost $800. I honestly don't know how they are producing this set and not losing their shirts. Full tang design (One piece of steel from tip through the handle to the butt), and has nice glass fiber reinforced polymer handle material. I can't find any reference to this set in particular for what steel is used, but based on using various steel through the years I have a pretty good idea what this probably is. (BTW, I hate to break to you. At this price, it's absolutely NOT German steel...and that's okay anyway.) Brodark references Japanese VG10 steel with their other stand alone chef knives. It is common in the Chinese knife industry to copy an alloy alloy and call it by it's original name. It's NOT Japanese steel. What is commonly referred to as VG10 is 10cr15mov or 8cr15mov. Both are fine steel to use for a "general purpose" knife and perform similar to Japanese VG10, or even US made 440c stainless...perhaps even a little better than 440c. The steel in these knives is pretty dang hard, which makes me think it is 10cr15mov. The 10 is the Chromium content in the alloy. More chromium, more hard, more hard ='s more brittle. There is a balance of how hard without being brittle. Some knife makers use super hard steel to get a wicked sharp edge that holds for a while...buuuut then after a year of use you see all the chips along the edge or perhaps even a tip has snapped off. That's hard, brittle steel. You can't fix chips unless you grind them down and create a totally new edge on the knife and start over. These Brodark knives find a nice balance of hardness for edge retention but enough give to not chip or break off under general use. Like I said, almost 1.5 years of use and no chips, bends, or scratches. I still can't believe I paid around $50 for them. Incredible.
