Keep the OEM ECU and all its must-have features
The new ECU in your 900 ACE Turbo R, the Bosch MG1 is by far the most advanced in the snowmobile industry. It's part of the evolution of the Mach Z and Turbo R engine. Keeping this sophisticated ECU makes sense.
The new Bosch ECU is almost 2 years of development from a group of BRP and Bosch engineers. Without a significant investment made by an ultra-experienced and competent firm, it's impossible to match this technological advanced ECU.
The MG1 incorporates several essential features such as Cold Start Technology and the ultra-advanced and adaptive knock system that acts instantly to adjust the engine setting depending on the quality and octane rating to eliminate the risk of engine damage.
Ramp adjustment starting point for a stock spring and helix combination in good condition, to achieve the target RPM. Please note; a modified spring and helix combination affects the final result. Therefore, we cannot provide settings for every application.
The test should be performed as follows: accelerate quickly but gradually to avoid track slippage. While accelerating, wait for the RPM to stabilize, then take an RPM reading. If the RPM is too high, add weight; if too low, reduce the weight.
Note that surface conditions vary and affect RPM.
- Target RPM: 8100 - 8200
- PEFI Adjustable Ramp Kit SKI-900R-CLUTCH-RAMP-77G
- Set to a total weight of 80.5g (use purple or blue Loctite).
- A screw head flush with the top of the hole (at the heel) is the most common setting.
*** You must install an adjustable ramps' kit to achieve the perfect RPM (8100-8200 RPM)
*** Addition of a Precision EFI Blow Off Valve is highly recommended.
