ISM – What it does

The Intercooler Spray Manager lets you decide when you spray water onto the intercooler (eg when intercooler outlet temp is above X temp and RPM is above 4000). Any 0-5v source can be used as an input.

The Intercooler Water Spray Manager also lets you choose two spray duty cycles, Stage 1 & Stage 2. Stage 1 is for normal driving, Stage 2 for bigger engine loads. For example you could set Stage 1 to spray water for 0.5 seconds every 30 seconds and Stage 2 to spray for 1 second every 15 seconds.

By controlling when and for how long water is sprayed onto the intercooler, the effectiveness of the spray can be maximised and water can be made to last longer.

You choose your settings and the ISM runs in the background, the only thing you need to do is to refill the water.



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

1 x RPM Signal. Signal must alternate between 0 volts and 5-15 volts. eg smart coil signal.

Important: Read here to understand what type of RPM signal the ISM requires


1 x 12-15 Volt (Battery voltage) – Solenoid, 5 amp MAX

1 x 12-15 Volt (Battery voltage) – Water Pump, 5 amp MAX. Note: If you need more than 5 amp capacity use this signal to power an external relay (not included)


Duty Cycle

-Dual stage & 3D user programmable duty cycles

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

-Set “higher” duty cycle for higher temperatures/qualifying

Duty Cycle Programming

Set “on time” from 0-1.5 seconds in half second steps

Set “off time” from 3-120 seconds


“Low” duty cycle: On time 0.5 second, off time 100 seconds, when MAP sensor over 50% and RPM over 3000RPM.

“High” duty cycle: On time 1 second, off time 20 seconds, when MAP sensor goes above 50% and RPM goes over 3000RPM (Low duty cycle/Stage 1 thresholds) and TPS is over 80%.


Better cooling because we are not saturating the surface of the intercooler

Make water last longer because, again, we are not saturating the surface of the intercooler

No distraction for the driver, the unit controls the spraying process completely automatically. The tank just need to be refilled.


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 and use 12v signal to trigger the pumps.

Here is a guide for making your own, high quality, DIY intercooler water sprayer

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.

Intercooler Water Spray Controller – 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
