ECU Flashing

Quad Squad Performance has partnered with Monster Fuel Injection to offer a premium ECU Flashing service right here in Australia.
What is ECU flashing and Why do I need to flash my ECU?

When ATV/SxS manufacturers build and design a new vehicle they don’t know exactly where or how it will be used and they need to be very basic with the information they put in the ECU (also referred to as the “tune”) so it works ok in a wide range of applications and with differing emission limitations from around the world.  The standard tune is always a compromise that misses the best performance and efficiency.  Re-flashing your ECU (optimising your tune) to suit your application will give you improved performance and efficiency.

A Quad Squad Performance ECU flash will change your ATV/SxS fuel and ignition mapping to improve power, torque and throttle response.  Engine accessory and other vehicle parameters are also finely tuned for your application.  Adjustments such as running temps, torque limiting, speed limiters, rpm limits and fuel consumption/economy.  ECU tuning also allows the power delivery to be customised to the way the rider/driver wants.

Every tune can be tailored to suit your needs, including engine modifications and the way you prefer to use it.  We have tunes for Recreation, Racing and Work applications.

But my ATV/SxS is E.F.I so it tunes itself?

This is a common misconception.  Your ECU has information (the “tune”) loaded onto it from the factory and relies on sensors on the vehicle to give information to the ECU to allow it to recalculate only some of the information to allow for air temperature, air density and engine temperature changes based on the information that is in the ECU to begin with.  This "base" information is what is changed when flashing your ECU.

How do I get my ECU flashed?

All you need to do is place an order for your model(see links below) then remove your ECU and send it to us at 5/8 Normanby St. Warragul, 3820 Victoria. Be sure to include your order number thats given to you at checkout along vehicle/application details and we’ll do the rest then send it back to you ASAP.  We can usually flash ECU’s within 48hrs of receiving them so your downtime is minimal.  Sometimes we get super busy and it can take a little longer, but we will always try to get your ECU back to you ASAP.  If we are experiencing longer than usual completion times we will notify you straight away.  You can also send an email to to check lead times before sending.

I live interstate or cant bring my ECU to you during business hours-what do I do?

ECU's are very robust, we suggest you wrap your ECU in bubble wrap and cardboard for protection and send to us with a trackable freight service like Express Post, TNT or Toll Express.  Unfortunately Quad Squad Performance cant be liable for anything that happens during the freight process as its carried out by a 3rd party and is out of our control.  We’ll return the ECU with the freight service you select- either Express Post, TNT, or Toll Express and can provide freight insurance at charged cost if you would like it.

Is ECU flashing safe? Will my engine blow up?

When done correctly ECU flashing will have no negative impact on your engine life.  In fact, once your ECU is flashed things will likely run much cooler and more efficiently which will extend a properly maintained engines life.  All of our flashes are extensively developed and have hundreds of hours of dyno and field testing so you can be sure you’re getting the best service.
