Stage 1 Specifications

No Speed Limitation
Tune RPM Limit: 8500 rpm

Unleash momentum. Unleash sharpness. Unleash potential.

Developed by us to bring out the full potential of the 900 Ace Turbo engine. This is our top tuning stage for the 900 Ace Turbo. It combines carefully selected hardware upgrades with the renowned Maptun software to deliver a truly special driving experience.


A massive increase in horsepower by 60-70 hp over stock, improved throttle response and seemingly endless resources of performance!


All our tunes for the 900 Ace Turbo comes with the option of a MAP-switch feature that will reduce power in STANDARD drive mode and generate max power in PERFORMANCE drive mode.This will be helpful when fueling low octane fuel or if you want better fuel economy while maintaining some 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. Additional hardware (exhaust, hoses, injectors, clutch kit and adjusted wastegate) is required.


Our tuning engineer’s comment:
”First of all, the Stage 3 is not for the faint of heart. If you are looking for a ”slight performance increase” this is not for you. This is for the thrill seeker who never seems to get enough power, speed and kicks.


To go beyond our Stage 2 we added upgraded injectors, adjusted wastegate cracking pressure and installed reinforced pressure hoses. This allowed us to push performance even further in a safe and controlled way. The result is massive increase in performance while still keeping to our filosophy of drivability and ”useable power” at any time. We managed to achieve a very wide power band from 6000 to 8500 rpm that will satisfy even the most demanding racers and speed freaks out there!”

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 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.

Our tuning engineer’s comment:
" - The 900 Ace Turbo was widely anticipated before its release in 2019. The engine is based on the popular and durable Rotax 900 Ace which is a great platform for supercharging. However, there where two concerns from customers; First of all the power was perhaps a bit below (especially at the very top) and second of all the electronic throttle felt a bit ”laggy”.


With this Stage 1 tuning software the engine really comes to life! The power and torque delivery is super-smooth with that extra useful power especially at the very top-end and the throttle response is almost instantaneous.”

Our tuning engineer’s comment:
”Listening to our customers and ambassadeurs wants and needs we created the Stage 2 for the 900 Ace Turbo. The addition of a sports exhaust system really opens up the possibilities to get even more out of this great engine platform. There is a noticeable increase in power and torque over Stage 1/Stage 1+ for the entire rpm-range. The most significant increase is seen (and felt!) in the midrange and from about 7000 rpm you’ve got almost peak power all the way to the rpm-limit. All this with outstanding throttle response and almost instant spool-up makes for an experience far beyond the ordinary!”

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 ETEC 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.
