New Methanol Injection Controller

[coolingmist]

As a new sponsor of this site I'd like to say we are happy to have the opportunity to serve this board and its members.

Once you read this thread you can visit us at http://www.coolingmist.com/controllerspecs.aspx to see a picture of our product and see pictures of how you can change the output curve.

Coolingmist does things right. When we set out to design a product...simply put...Its better. When we designed our checkvalve we had it made out of brass and gave it a 45 lb cracking pressure. This makes it bullet-proof and the safest water/methanol injection kit you can put on your car (much more reliable than ANY solenoid or cheap plastic checkvalve). When we designed our kits everything was designed to be put together seamless.

Our controller is no exception, infact it re-writes the rules of controllers. We are the first and only controller on the market that is user-configurable. This makes a great option for those that want to tune to the last detail. No other controller will allow you to do that. For those that just want a simple controller you are in for a pleasant suprise. The Vari-Cool coolingmist controller is designed to be superior to all other controllers out of the box. This means you can install the controller on your car and be able to fine tune to your vehicle far better than any other controller on the market..without even using the software.

Look at other controllers on the market and compare. We designed ours to compare favorably to all other controllers in Design, ease of use, performance, durability and functionality. We are certain that we can say this is the best, highest performing, most user friendly controller ever built.



The Vari-Cool Coolingmist Controller is a revolution in terms of what a water/methanol injection controller is thought of. say good bye to pre-programmed controllers that give you no options for tuning. Our controller is fully configurable via the coolingmist vari-cool software. This software program allows you to program the unit to your specs with your laptop. For those of you that do not want to use your computer, the system comes pre-programmed with a base map and has 10 different curves you can choose from. Unlike the other controllers that have a built in linear algorithm, we give you a choice of 10. this makes the Coolingmist Vari-Cool the controller of choice for tuners and for individuals that want the absolute best controller . This controller is expected to be in stock in January. MSRP will be $199.95.

Controller Specifications:

16 Bit High Speed Digital Signal Processor (DSP) Control that operates at approximately 0.5ms.
A tunable linear control algorithm updates the Motor control output > 2000 updates/second.
16 Bit Motor current control resolution provides finely tuned output adjustments of 0.001% of the maximum Motor current draw.

General Specifications:
10 position tuning switch limits maximum pump pressure to prevent intake engine bogging down.
Boost pressure operating ranges 0 – 30 PSI, 0-100 PSI or 0-30” Hg vacuum (depending on model #) with an integrated Pressure sensor.
Variable Min and Max boost pressure settings with large knobs and resolution of 0.01 PSI over the boost pressure operating range.
12 bit resolution reading on boost pressure (0.01 PSI resolution over boost pressure operating range).
A single green status LED simplifies operating status determination.
High speed RS232 serial communications port operating at 115200 baud to allow data logging, analysis and custom configuration/calibration of the unit using Vari-COOL PC software.
Coolingmist Vari-COOL software provides precise adjustment and configuration of VariCOOL operating parameters.

Physical Specifications:
Operating temperature range of 0 - 85°C (32 - 185°F)
10/32 Male threaded pressure input port accepts 10/32 Female to barbed tubing connection that can be easily sized to accommodate various tubing sizes.
Heavy gauge all aluminum enclosure construction with black powder coat paint for long lasting finish durability.
Enclosure mounting tabs provide ease of mounting in any location.
Durable label is smudge proof, chemical and petroleum products resistant and does not deteriorate over time.

Electrical Specifications:
Operates on wide input voltage range 7 – 26 VDC
Up to 30Amps DC to the pump across the operating voltage range (using proper wiring and fuse).
Unit itself draws less than 50mA with the Motor control output turned off. This means that if the car is not running, this unit can run off the battery alone for a very long time.
0 – 5VDC Auxiliary Input with transient voltage protection and 12 bit resolution (0.01 V resolution) can be used with any 0-5VDC sensor to control the Motor Output level or monitored (via serial port).
External automotive style fuse protection that can easily be sized to accommodate various motor sizes.
Can be wired directly to the electrical system for always on operation or wired through an Automotive Relay connected to the ignition switch for ignition switch operation.

Vari-Cool Software Specifications: Overview

Software talks to the Vari-Cool unit using a serial port that will work with any compatible PC running Windows 2000, Windows XP, Windows 2003, Windows ME, Windows 98, or Windows NT.

Operation

Vari-Cool operates in 2 modes. Run mode and configuration mode. In run mode, you monitor data collected by the Vari-Cool unit. In configuration mode, you can set tuning and calibration parameters.
Serial Port Vari-Cool serial port has the following settings:
Baud Rate 115200 baud
Data Bits 8 bits
Stop Bits 1 bit
Parity None
Flow Control None

Serial Port

The Vari-Cool serial port connector is a standard 9 Pin Female DSUB style connector. The Vari-Cool is configured as Data Communications Equipment (DCE device). The connector pin out is as follows:
DSUB
2 TX – Transmit Data
3 RX – Receive Data
5 GND
* Other pins are not connected and have no function

Run Mode (Status LED Fast Flash)
The Run Mode is the default operating mode of the Vari-Cool controller. While in the Run Mode the Vari-Cool controller continuously runs the motor control processing loop. This loop reads the inputs and adjusts the motor control output accordingly. In the Run Mode a Status Message can be requested or setup to be sent automatically on a configurable Timer period.


The following data values are monitored, logged, and charted with the software:


Operation mode (0=Run Mode, 1=Configuration Mode)
Boost Pressure Reading (PSI or “Hg, whichever applies)
5V Auxiliary Input Reading (%)
Output to Motor (%)
Minimum Pressure Setting (PSI or “Hg)
Maximum Pressure Setting (PSI or “Hg)
Tune Switch Setting (1
10)
Auxiliary Input Switch Setting
Controller Status

[b}Configuration Mode (Status LED Slow Flash) [/b]

The Configuration Mode of the Vari-Cool controller provides an operating mode in which Configuration Parameters can be read and written.


The following parameters are able to be modified:


Minimum Motor Output (%) – This is minimum output at which the pump is able to operate and spray water. This value defaults to the requirements of the pumps we supply. If you use a different pump, you may need to modify this value.

Maximum Motor Output (%) – This is the maximum output at which the pump should ever operate. This value defaults to the requirements of the pumps we supply. If you use a different pump, you may need to modify this value.

Minimum Pressure (PSI or “Hg) – This is the minimum calibrated range of the pressure sensor supplied with the Vari-Cool unit.

Maximum Pressure (PSI or “Hg) – This is the maximum calibrated range of the pressure sensor supplied with the Vari-Cool unit.

Tuning Parameter – This is a parameter that will change the shape of the output curve to the pump. This can be used to account for any non
linear effects of your vehicle, pump, etc. By default, the unit will be calibrated; however you may wish to work with this curve to obtain even better results.

Can I use the controller as a retrofit to an existing system on a Supra single?

Yes our controller will work with any 12V pump. There are only 4 wires to connect, the boost source or the 0-5V input. Very simple. Thanks!
