More power. Better response. Faster spool-up. Outstanding drivability!

Get the most out of your Ski-Doo e-tec 850 Turbo with our tuning software. It’s calibrated for the northern climate, tested by our ambassadeurs and carefully refined using all our knowledge in snowmobiles and engine management. The Stage 1 gives the Ski-Doo more power and torque across the entire RPM-range - especially in the mid-range - for outstanding drivability! Our main focus is always overall drivability and ”accessible performance” at any time, instead of just peak power.

Programming is performed in a couple of minutes with the MaptunerX and you get free access to all tuning software available for your vehicle.

Our tuning engineer’s comment:
” - The feedback from our ambassadeurs and customers after testing our tuning for the Ski-Doo 850 Turbo has been overwhelming. The increase in response and drivability that we have achieved with this tune is beyond that we expected. This simple makes the already great Ski-Doo 850 Turbo an even better (and more exciting) machine to ride!”

What’s MaptunerX?

The MaptunerX is a handheld programming unit developed by us and made here in Sweden. It’s used all over the world for a wide range of vehicle types for tuning, diagnostics, service, monitoring and logging. By connecting to the vehicle’s ECU the MaptunerX has full access to perform advanced adjustments but still keep all the factory safety features activated. This is by far the best way of tuning a vehicle, but it’s a time-consuming development process for us - but for you it only takes a couple of minutes in an easy step-by-step process. We’ve made all the hard work - so you don’t have to! Connect the MaptunerX, sync it to your MyMaptuner-account, select tuning stage and let the MaptunerX perform the programming. It’s that easy!

In addition to tuning the MaptunerX has apps and features for resetting service, manage keys, reading and clearing fault codes, resetting throttle position, monitoring live engine data, logging engine data etc. The available apps may vary depending on the make and model of the vehicle.

The tuning development process

The Ski-Doo 850 e-tec Turbo (and it's naturally aspirated sibling the Ski-Doo e-tec 850) is our first ever 2-stroke tuning stages. We always set the bar very high for that we want to accomplish when we begin developing a new engine tuning software. For this particular model, the Ski-Doo e-tec 850 Turbo, our development has taken months in order to make sure we bring our customers the best possible performance in every aspect. The first thing we do is getting familiar with the vehicle and the engine construction, and perform thorough tests on the stock configuration in our dyno facility. Already at this stage we install a variety of sensors to accurately measure pressures, temperatures, fuel, flow and power. With full access to the ECU and all its different maps we can begin localizing the necessary parameters that will need to be adjusted. By adjusting in small increments and performing lots and lots of test runs in the dyno, we can closely monitor the process and record how the engine responds to the changes. We stress test the engine by running it hard over extended periods of time, at both full and partial load, to make sure temperatures and other parameters don’t reach harmful levels over time.

Once we have achieved the power figures we desire, field testing begins. Driving the vehicles in the same environments as our customers is crucial to getting the best possible driveability. All the sensors are still installed on the vehicle and we get copious amounts of data for review. Thanks to the MaptunerX, we can also test, adjust and refine the tune on location during field testing.After field testing the software we hand it over to our ambassadors and racers. This is the key to test the tunes in real-world situations and with many different driving/riding styles. Using the MaptunerX Data Logger we get feedback and even more data to analyze. We can then adjust the tune individually and let different drivers try out different tunes to see what works best.

Stage 1 Specifications

No Speed Limitation
Tune RPM Limit: 8300 rpm

Even more power, better response, faster spool-up and outstanding drivability!

Get the very most out of your Ski-Doo ETEC 850 Turbo with our tuning software and a performance pipe. By replacing the stock exhaust pipe with a performance pipe we're able to go beyond the hardware limitations that comes with "just" a software upgrade. The Stage 2 really brings out the potential of the 850 ETEC Turbo engine with exquisite characteristics.

It’s calibrated for the northern climate, tested by our ambassadeurs and carefully refined using all our knowledge in snowmobiles and engine management. The Stage 2 not only gives the Ski-Doo more power across the entire RPM-range compared to Stage 1 - but the key factor is the torque delivery which brings more torque AND a wide torque band. Our main focus is always overall drivability and ”accessible performance” at any time, instead of just peak power, and we couldn't be more happy with the result of this Stage 2 for the Ski-doo 850 ETEC Turbo.

Programming is performed in a couple of minutes with the MaptunerX and you get free access to all tuning software available for your vehicle.

” - The feedback from our ambassadeurs and customers after testing our Stage 1 for the Ski-Doo 850 Turbo has been overwhelming. The increase in response and drivability that we have achieved with this tune is beyond that we expected. And now, with the added performance pipe and our tuning software for Stage 2, it's even better!”
