What the MoviChip ISM does

Programmable and automatic, 3D and dual stage, intercooler water sprayer controller

-Fully automate the intercooler spraying process

-Make your water last longer

-Get better cooling performance

-Reduce/eliminate delay of water spray cooling

-Simplified installation. All wiring in engine bay

 

Inputs

2 x 0-5 Volt  – Analog (eg MAP, MAF, TPS, Temp)

1 x 0-5 Volt – Timing Signal

1 x 0-5 Volt – Flow Meter Signal, Fail Safe

Outputs

1 x 0-15 Volt – Solenoid, 5 amp MAX

1 x 0-15 Volt – Water Pump, 5 amp MAX

1 x 0-5 Volt – Error Output (for a piggyback/standalone) ECU

1 x 5 Volt – Flow Meter Power

Out of stock

Failsafe

-Over flow Detection

-Under flow Detection

-Flow Detection (ie flow when there should be no flow)

All these settings are user programmable via the Android App. You set the typical, normal flow signal. Then set the tolerance for this signal ie how much +/- is acceptable.

For flow where they should be none, set the base signal from your flow meter when there is no flow.

When the flow exceeds or subceeds the set values the unit will attempt to cut power to the pump and the solenoid valve and it will send a 4+ volt signal to an external source eg LED, piggyback ECU. Note the failsafe may not compensate for wiring errors eg exceeded voltage input or exceed current source or drain.

Duty Cycle

-Dual stage & 3D user programmable duty cycles

-Set “low” duty cycle for normal conditions/driving

-Set “higher” duty cycle for higher temperatures/faster driving

Duty Cycle Programming

Set “on time” from 0-3 seconds

Set “off time” from 3-120 seconds

Examples

“Low” duty cycle: On time 2 seconds, off time 100 seconds

“High” duty cycle: On time 2 seconds, off time 20 seconds

Problems with a typical intercooler sprayer

Manual activation. Difficult and inconvenient for the driver to consistently wet their intercooler when they are driving, especially in race conditions

Wasting water. Uncontrolled spraying can waste water ie spraying when it is not necessary.

Installation in cabin. Running switches into the cabin adds complexity to the installation, especially if more than one switch is used.

Slow response. Water spraying of an intercooler needs to be done in advance. It takes time for the water to spread to the inside on the intercooler core. The intercooler needs to be constantly wetted or wetted in advance so the evaporative cooling effect is working when you need it.

ISM Solutions

Automatic activation. The MoviChip Intercooler Spray Manager lets you program the conditions under which the intercooler should be sprayed. It is a fit and forget product. Program the settings you need, close the app and then any time you use the car the unit will spray the intercooler in the background. No need for any intervention from the driver except for filling the tank with water.

Maximise water. With the MoviChip Intercooler Spray Manager (ISM) you can set your “ontime” for spraying and your “offtime” for spraying, plus the conditions when you spray. In short you can keep the water spraying to the absolute minimum you need for increased cooling performance.

Easier Installation. The ISM is mounted in the engine bay and is programmed via Bluetooth using the Android App. There is no need to mount buttons or switches on the dashboard.

Immediate response. The ISM lets you constantly keep your intercooler wetted, the intercooler is constantly benefiting from the evaporative cooling effect. Your intercooler is primed and ready.

What to look for in an intercooler spray system


Does It Include The Pump, Jets, Hoses etc?

No. The MoviChip Intercooler Spray Manager is an ECU designed to enhance the capability of intercooler spray kits which are already on the market. For example DEI, Devil’s Own or you can even build your own.


What Settings Can Be Adjusted?

Choose up to three sensor thresholds when the spray should be activated.

For example..

Choose to spray the intercooler only when your MAP signal is above 60%, the RPM is above 4000 and your intake air temperature sensor is reading above 50%.

After you have chosen your activation threshold, you choose the duty cycle (ie how long the pump should spray for and how big the gap should be between each spray event) and that’s it, you are done!

Dual Stage.

If you are using a second nozzle or pump you can program the second stage in the same way but after the first pump.

For example, if the first pump/nozzle is activating at 60% MAP, 4000RPM and 50% temperature, you can have the second pump spraying at 70% MAP, 5000 RPM and 70% temperature.


In Normal Use

The Intercooler Spray Manager (ISM) will work in the background, spraying your intercooler whenever these conditions are met.

The MoviChip Intercooler Spray Manager will work with any aftermarket intercooler water sprayer except those that work with a motor controlled with PWM (Pulse Width Modulation), we do not know of any intercooler sprayer that works with PWM. (so it should work with every intercooler water sprayer kit).


How Is It Programmed?

Using the MoviChip ISM Android App you program the unit wirelessly.

Once you have found the best settings for you, close the app and the ISM will work in the background every time you drive the car, spraying the intercooler at the times and conditions you have chosen in the app.


Using an intercooler sprayer kit without a controller

Generally all kits are activated by a button on the dash, even the factory fitted sprayers work the same way, the 2018 Subaru Impreza STI for example.

This activation method is completely unsuitable in race conditions.

The driver cannot constantly monitor engine parameters to choose when is the best time to spray the intercooler and how long to spray the intercooler for.

When you are driving fast there are more pressing matters to deal with.

Like the driving the car.

The MoviChip Intercooler Spray Manager (ISM) is completely self contained in the engine bay, automates the entire intercooler spraying process and needs no input from the driver. It is a fit and forget item (you just need to keep the water tank filled!)


Intercooler Spray Manager – Installation

You don’t need to run any wires into the cabin, the ISM unit is mounted in the engine bay and the settings are altered wirelessly via Bluetooth and an Android equipped smartphone. This also removes the need to fit devices inside the cabin like buttons, and throttle position switches. The MoviChip ISM massively simplifies the installation of intercooler water sprayer kit and does not need any holes or mounts to be put on the dashboard


How Does The Pump Switch Off?

Using the example above again, when the MAP signal is less than 60% or when the RPM is less than 4000. When either of these two conditions are no longer met, the pump is deactivated.
