PS-6 Lynx 2025 Build -- MaxxECU engine management system
The MaxxECU engine management system is the most important and critical component that makes this PS-6 Lynx 900R build possible. It sets PS-6 apart from the rest and without it, PS-6 would be just another pimped up 900R.
Here is some background as to why we only use dedicated standalone engine management systems in all our build projects.
Interesting fact...
Did you know Precision Sports was the very first company ever to reflash a snowmobile ECU back in 2007. At the time, no other companies were offering this service.We enjoyed a massive commercial success at the time, essentially reflashing Bosch ECU's used on all turbocharged Polaris snowmobiles produced between 2006-2014. However, we quickly realized reflashing ECU's was not optimal and we opted out of the market in favor of developing plug and play MoTeC standalone ECU's for the snowmobile market. This was also the time when countless shops entered the reflash market competing one another on price point and rushing imperfect tunes on the market to gain visibility and momentum. We did not want to be part of that and abandoned selling reflashes over 10 years ago. Experience gained in the early years prompted us to focus our efforts on development projects not feasible using stock reflashed ECU's.
The MaxxECU system installed on PS-6 is the same we sell to all our customers around the world for their 900R snowmobiles. However, it is set up with several experimental features that are specific to PS-6. The base configuration of all MaxxECU systems have the following functionalities:
- Closed loop fuel, boost and knock control
- User defined boost targets
- User defined RPM limits
- Automatic self tuning capability with ongoing fuel adaption capability for those varying operating, elevation and terrain conditions
- Staged injection allowing the use of hybrid fuel configurations
- Automatic octane detection and power derating from Sport to Standard mode in situations when octane is not high enough for Sport mode
- Bluetooth communication with and Android device to create high end custom dash displays
- Launch control (2 step) from a dead stop
- Launch control from a rolling start
- User configurable data logging for engine operation review and editing
- Automatic engine starting at the simple push of the start button much like all modern cars
- Vehicle immobilizer to prevent theft
- Full compatibility with all Skidoo dash from 2019 to present
- User defined cooling fan operation
- Integration of CAN keypads for extra accessory control
- And... the list goes on.
This is the 7th year using and selling these systems for 900T and 900R Skidoo snowmobiles. We know it is indisputably the absolute best system out there. It is stable, will start engines in freezing temperatures down to -35C, will idle like a stocker, will protect the engine against abuse and will allow any power output level with the only limitations being the hardware surrounding the engine and/or the fuel octane used. We have never seen one single, and let's repeat again, not one single engine failure with these systems since 2019.
Our next and final chapter for this build will be about real world testing of PS-6.... attached picture shows a sneak peek preview of an initial test result on the snow at 35psi boost... stay tuned.
