Ski-Doo/LYNX 850 ETEC Stage 1 - 170 Hp
Get a powerful performance upgrade with the unmistakable Maptun tuning software!
Plug-in the MaptunerX a let it reprogram the ECU. That's all you need to do to unleash the performance in your Ski-Doo 850 E-TEC. The Stage 1 tuning software is calibrated for the northern climate, tested by our ambassadeurs and carefully refined using all our knowledge in snowmobiles and engine management. The Stage 1 brings more power, mostly in the higher rpm-range, and a very appealling characteristic which Maptun is renowned for.
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 once the tuning license is assigned.
Our tuning engineer’s comment:
” - The feedback from our ambassadeurs and customers after testing our tuning for the Ski-Doo 850 E-TEC (and it's sibling the 850 E-TEC Turbo) has been overwhelming. The increase in responsiveness and drivability that we have achieved with these tunes is beyond that we expected. This simply makes the already very capable 850 E-tec an even better ride for all the racers out there!"
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 (and it's turbocharged sibling the Ski-Doo E-TEC 850 Turbo) 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 850 ETEC, 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 external 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.
