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.

Great thowback to the OG Ironman, but Amazon's listing gets it undue negativity.
Color: Black/Yellow
Amazon's listing is not very good with it's wording so this watch has gotten undue negative reviews. I've seen this model listed as both the Endure 30 and the Original 30 Shock, it has 1 alarm with 3 different modes (not 3 separate alarms), 200m WR, ISO shock resistance, (reverse) Indiglo with night mode, 2 time zones, 12/24hr time, 30 lap stopwatch, 24hr countdown timer (repeatable), and day/date (MM.DD or DD.MM). Its basically a slightly updated feature set compared to an Ironman 8-lap. This watch is great, it's got the look of the original Ironman 8-lap with modern guts. The only minus for me is it could be a little slimmer on the wrist, but I also didn't realize it was shock resistant when I bought it. For comparison, it is a few mm smaller in all dimensions than a G-Shock G2300/G2310/GW2310 series. The band is similar to G-Shocks in that it is formed/molded around the wrist but like the case it's still slimmer in the way it wears around the wrist. Not as slim as an F91W but not as massive as any G-Shock basically. The module has a better display with bigger numbers than the above mentioned Casios. With the exception of the lap memory, the G23## G-Shocks have more features, but the Endure 30 is much easier to use thanks to the display and larger buttons. If you want 3 alarms you need the very similar Classic 30. The main differences being the Classic has 3 separate alarms (not 1), occasion reminders and 3 time zones but losses the Ironman 8-lap look, the shock resistance and it's only 100m WR. The Classic seems to come in at least two case varieties (chunky or slim), two sizes and many color combinations. If you only need the Endure 30's features but want a different shape/size/style/slimmness, I believe the Essential 10/30 and BASIC Transit models are functionally the same with only different lap memories, WR, and no shock resistance. Unfortunately, Timex doesn't easily identify the actual module used in a watch like Casio, so the best way to figure out what features a watch has is to lookup the watch model on the Timex website. Of course the manuals do not always match the marketing names they have used over the years (Endure/Classic/Essential/etc), and each manual covers a few shapes/sizes of watch but just search for the model number in the manuals sections and you'll eventually find the right one. If no manual pops up right away delete digits from the right end of the model number until a manual is found, I believe those last digits only indicate slight variances in style/color that are not important to functionality.

Good interface but unwearable watch band
Color: Black
This review will be divided into 3 sections: looks, usability, and comfort. LOOKS I guess there's not much to say as style is very individual. I think this watch looks good for what you pay for it. USABILITY What I liked about this watch is that I could use it right out of the box. I have had basic Timex digital watches before (never this exact interface), and I was able to quickly figure it out. A quick glance at the manual to make sure I wasn't unaware of any features and I had 100% grasp of all the watch's features. The Timex interface puts many others to shame with its user-friendliness. On this model Timex has added a 'guide' on the display that tells you which button will do what-- increase number, decrease number, etc. This is cool. If you're even remotely handy with interfaces, once you learn this one, you'll know it backwards and forwards, and even if you forget, there's the in-display guide. The functions are standard for a Timex digital-- time and date, stopwatch with lap timing, countdown timer, and alarm. There is a 2nd time zone but no dedicated mode for it. You access it by holding the 'start' button when in the time mode. I like this feature as I occasionally need to know when to call people in 1 particular time zone. But, for example, if you are often switching back and forth between 2 time zones, you will have to reset the time to have the watch display the correct time at all times. And if you need more than 2 time zones, sorry, out of luck. Stopwatch (chrono) is good. Don't use the lap counter much but it seems to work well. Some have complained that the 'start' and 'stop' should be on the same button. Overall, it is a very uncluttered and usable interface. At first I thought it was very inaccurate at timekeeping, but it must have gotten accidentally reset because over the few months since I set it, it's only a couple seconds off from time.gov. very good timekeeping. It seems very water resistant. I have taken it swimming, surfing, and it held up fine. I haven't thoroughly tested its shock resistance but it has done some hiking and climbing where it got banged around a bit and it still works. COMFORT Unfortunately what the watch has in user interface usability, it totally lacks in comfort. The strap is a huge disaster. It is very rigid and uncomfortable. The 'waffling' or indented designs near the bezel on each side of the strap create areas where the strap digs into the wrist. with any prolonged wearing, it gets worse and worse until your wrist is begging you to take it off. The strap is just absolutely godawful. I have read reviews where G Shock owners said it was very good, well though out and comfortable. If that is the case, I shudder to imagine what a G Shock is like on the wrist. If constant pinching around sensitive areas on the side of the wrist seems like it would be the kind of thing to bother you, avoid this watch. I tried swapping it for another Timex band, which amazingly enough was uncomfortable it a DIFFERENT area! It seems Timex doesn't put much thought into their bands-- no part of the band should dig into the wrist. That's just obvious. CONCLUSION I really want to like this watch, I do. It's good-looking. It's very usable in terms of features. But the strap is terrible, so much so that the watch is unwearable. Unfortunately it took me about a week to figure this out, during which time the watch got sufficient wear so that it is no longer new, returnable condition. I am keeping it, using it as a 'beater' watch in the gym (I put my watch on the ground in the gym). If you purchase it I recommend you wear it for a good few hours while not doing anything that will scratch it, so that you can return it if need be.
