The stage 4 controller is the most advanced programmable water methanol pump controller on the market. It is capable of simultaneously driving two individually-controllable water methanol injection (WMI) pumps and four individually controllable anti-siphon solenoids, Fast Acting W/M injection valves, auxiliary high impedance injectors or any combination thereof. It has two pump outputs is capable of supplying up to 15A to the connected pump.

Stage 4 Controller Strategy: 

Standard progressive controllers can only drive a single delivery pump. They also usually have only a single channel for driving an optional anti-siphon on/off solenoid valve. This makes them somewhat less than optimal for use in direct injection set-ups or staged set-ups that require a lot of stages.

The higher-end European controllers can only drive a single delivery pump and one “fast response valve”. They cannot be configured for multiple stages of delivery, but they are provided with optional direct injection manifolds for 4, 6 and 8 cylinder configurations.

Our stage 4 controller can drive two delivery pumps and four on/off solenoids or “fast response valves” or two of each solenoid type. The users can implement a VPD control approach based on RPM, boost or another 0-5V signal of their choice. They can also implement the FPD-VSD control strategy that is based on RPM, boost or another 0-5V signal. Because the Controller has two PWM pump outputs and two General Purpose outputs (GPOs) which can either drive On/Off solenoids or PWM “fast response valves”, the user can implement a hybrid VPD/FPD-VSD control strategy or something completely new and unique.

TorqTune Software

In spite of its sophistication, the software is extremely easy to install and configure with our intuitive TorqTune PC software.

This free software allows users to fully configure the operation of the Controller. Certain parameters, such as duty cycle maps, can be adjusted with the engine running for real-time tuning. Additionally, TorqTune allows the user to live view many of the unit’s internal parameters, log them to a file and save them for later playback or for sharing with others. These advanced functions allow the user to observe the effects of various configuration changes in order to achieve unprecedented control of their methanol injection and/or fuel pump operation.

TorqTune software can store your Controllers configuration settings in special TTINI files that you can store on your hard drive or share with other users. Other users' configuration files can be loaded into your Controller and used "as-is" provided your set-up is the same as the other user's or they can be used as a starting point for your own customization. TorqTune software can also log and play back saved log files which can be analysed in TorqTune or in Excel. These features make the Controller and TorqTune ideal for tuners who need to work on their customers' vehicles remotely.

The feature set provided by our controller and its accompanying TorqTune software is not available with any other water methanol injection or fuel control system.

A Controller that Evolves with your Setup

If you don't need all of the Controllers advanced functionality right away, you can use TorqTune to configure the Controller to operate as a dumb "progressive" controller equipped with two adjustment trim-pots for manually setting the pump activation boost point and the "full pump speed" boost point.

The controller is designed to be future-proof. Its internal unit firmware can be upgraded from your PC so you can continue to take advantage of new features and enhancements as they are rolled out. Simply download the latest firmware from our website and reflash your Controller from the TorqTune software. As always, all firmware and software updates are free for all our customers and our dealers.

Industry’s First TRUE 3D WMI Pump Duty Mapping

The Controllers water methanol injection delivery is fully digital and is completely customizable by the user through a 16x16 table (i.e. a 256 point map) which is downloaded into the unit.

Other water methanol kit providers state that their pump controllers are "digital", but what do they really mean by that. Sure, some of them come with a basic "digital" display that shows parameters like boost or pump duty, but how truly "digital" is their internal operation? As a true digital controller, the Controller is built around a fast microprocessor that performs 2-dimensional linear interpolation simultaneously in both vertical (boost or voltage) and horizontal (RPM) axes to generate pump duty values which change smoothly and gradually between all adjacent table cells. This is the same algorithm used in today's modern Engine Control Units (ECUs).

Need extra water meth at a certain RPM & boost point, in an otherwise linear map? No problem

Need to add a small dip in water meth delivery required at another RPM & boost point? No problem.

The other controllers simply don't provide this level of flexibility, especially not in one unit that can control four outputs each with its own unique configuration table.

The controller is supplied with a 4-Bar MAP sensor, but the TorqTune software allows you to configure the unit to use any 0-5V MAP or gauge pressure sensor of your choice. This is an important if you are using the controller on something like a high-performance diesel set-up that sees up to or over 100PSI of boost.

If you do not want to base your water methanol injection on RPM and boost, you don’t have to. Pump duty can be based on just RPM or just boost. Don't want to base the Water Methanol Injection control on boost pressure? Want to use some other 0-5V sensor or signal? No Problem. Select what you want to use for the vertical axis source

If other exotic or unorthodox water methanol control schemes are required, the Controllers two spare 0-5V analogue inputs can replace boost as the vertical axis in each of the tables so you can base the pump duty on another 0-5V signal, such as the MAF or the TPS. You could even base your water methanol delivery on the 0-5V output of an O2 sensor controller or even a simple manual pot. You are in full control of your WMI pump operation at all times allowing you to make it fit virtually any vehicle or engine set-up.

The Controller always stores the user-loaded 3D duty maps in its on-board, non-volatile memory. TorqTune software can store these maps in calibration files and allow them to be saved, opened, edited and shared. Pump duty cycle, boost, RPM and a number of other parameters can be logged and played back using the TorqTune software. Users can easily edit and customize the water methanol delivery calibrations for their specific engine configuration.

Low Power Outputs

Besides the two high power pump outputs, The controller also provides you with four low power General Purpose Outputs (GPOs) whose operation is also fully customizable through their own dedicated 256 point map tables that can vary the duty of each GPO based on engine RPM plus another 0-5V parameter such as boost pressure or a spare analogue voltage.

Other uses for these outputs are activation (or deactivation) of loads such as relays, lamps or LEDs that can be used to control other systems in the vehicle or provide visual indication to the driver based on the 256 point table configuration.

Spare Analog Inputs

The controller comes with two spare 0-5V analogue inputs. Either of these spare inputs can be used to control any of the four 256 point tables instead of the default MAP sensor.

Whether the two spare analogue inputs are used instead of the MAP sensor to control the duty of one of the outputs or not, both can still be used for live-viewing and/or data logging allowing the user to record and analyse parameters including, intake or exhaust temperature, throttle position (TPS), Mass Air Flow (MAF) reading, water methanol Flow Sensor output or Air/Fuel Ratio (AFR) taken from a Wideband O2 sensor controller.

Spare Logic Inputs

The controller provides the user with two active-low logic inputs. An open circuit on these two inputs is considered inactive. However, connecting either of these inputs to ground, through a switch or a relay, signals an active state to the controller and allows it to take a pre-defined action.

For example, if the user has configured the Controller for boost control, these inputs can be used to select between two boost set-points or put the car in valet mode where the boost is set to the lowest possible (i.e. wastegate spring) boost level. Many other uses are certainly possible and are only limited by the user’s configuration.

 Built-In Safety Features

Our stage 4 controller actively monitors the current passing through its dual high power pump outputs. The user is able to set the unit’s undercurrent and overcurrent limits using TorqTune software to guard against problems that could be caused by electrical malfunctions or component defects in their fuel or water methanol injection system. For example, if excess current draw is detected that exceeds the user-entered overcurrent limit; it could be an indication of a short circuit in the pump or in the wiring or a blocked line which is causing the pump to overload. On the other hand, if the current draw drops below the user-entered undercurrent limit; it could be an indication of a break in the wiring, an empty tank, or a faulty pump. The Controller can detect and flag these faults to the user or can take action like reducing boost to its lowest setting to protect the engine (only in configurations where the Controller is controlling the boost solenoid). This is a feature not available on any other controller.

Optional Displays

In most cases users will use a laptop or a tablet with a USB connection to communicate with the Controller and view, log and modify its various measurements and parameters. For users wishing to view just some of the parameters, The controller provides a low-speed serial communications port for displaying the following:

• Actual Boost
• Target Boost (if used)
• Auxiliary Input Value (if used)
• Battery Voltage
• Boost Solenoid Duty (if used)
• Main Output Duty
• Auxiliary Output Duty
• Engine RPM

Users can purchase separately DM1 display module or Bluetooth module, users can download the free TorqView software which allows them to view all important unit parameters on a small 7"-9" Windows tablet that can be mounted on the dash.
