This computer is a custom designed, standalone EFI (Electronic Fuel Injection) control  system specifically designed for use on boosted snowmobiles. This system completely eliminates the factory computer's control of the fuel injection.

  Unlike all other systems available on the market (including out older GEMS system) this unit is standalone. We refer to all the other systems available as "Piggybacks". The Piggyback's job is to fool and override the factory computer system into performing differently than its original designed. A piggyback intercepts the injection signal from the factory computer, modifies the signal and then outputs the modified signal to the injectors. The problem with all piggyback systems is that it never knows exactly what the factory system is doing. This is because the piggyback only has the factory computer's output as its input. The one exception to this is a boost sensor. In fact, the factor IAT (Intake Air Temp) sensor is disabled since the factory computer cannot comprehend the high air temperatures produced by super or turbo charging. The piggyback can only add or remove fuel based on boost. As anyone is aware who has ridden with a piggyback, is that they don't always run the same from day to day, location to location and sled to sled. The piggyback simply doesn't have enough data (or sensors of its own) to make accurate decisions. Take any piggyback on the market, tune it in a specific location then move to a different location (something 5000 feet higher or lower) and it will not run correctly without tweaking.

  Our standalone thinks for itself. It is a full featured computer and actually has more sensors than the factory computer. We include a MAP (Manifold Air Pressure, or Boost) sensor, BARO (BAROmetric pressure) sensor, IAT (Intake Air Temp) sensor and ECT (Engine Coolant Temp) sensor. We share the output from the factory TPS (Throttle Position Sensor) and the factory Crank Position sensor. There are no buttons to press and no knobs to tune. Its done. The system runs in a semi-closed look environment as a speed density system. This is the control systems used on all high performance high boost vehicles from cars and boats to motorcycles and aircraft.

FEATURES:
 - Includes a matched set of flow tested 750cc injectors (72#) (factory 330 nytro and 390 apex).
 - Includes Plug and Play wiring harness, which means no wiring to install.
 - Includes 3 bar MAP sensor, Baro sensor, IAT sensor & ECT sensor.
 - ECU (Electronic Control Unit) in Billet Case and potted for weather and vibration resistance.
 - Mounting brackets for ECU and Pressure Sensors.
 - Harness is upgradable for future Ignition Control.
 - Harness has direct connection output for our ProLogger Gauge (Tach, MAP and AFR)

 - Note, if  ECU is used with the ProLogger, the ECU is aware of AFR (Air:Fuel Reading).

The Dual Temperature version features user defined warning limits. Regardless of the current display setting (AFR/Boost/RPM or Oil Temp/Water Temp.RPM) the unit with switch to temp readout mode and flash the reading indicating a warning limit has been reached.

Total stand alone data logging and playback of air/fuel ratio, RPM’s, elapsed time, and manifold pressure in 1/10 second increments. The ProLogger will control conventional or delta p style race gate turbo systems. It will also control multiple stages of nitrous oxide or methanol injection with failsafe lean parameters you can program into the unit. Melted pistons due to lean conditions are a thing of the past. There is NO need to get out the laptop as it is NOT REQUIRED FOR SETUP OR FUNCTIONALITY.

The possibilities are endless; performance tuning, snowmobiles, quads, UTVs, drag racing, circle track, road racing, off road, motorcycle, sport compact, speed shop tuning, etc.

The ProLogger is manufactured from an industrial grade black anodized aluminum housing made to withstand the harsh environment of 3000 horsepower engines. The inside components are made with state of the art surface mount technology manufactured to ISO 9001 standards and all American made.

The ProLogger Basic comes with the controller, wideband oxygen sensor, wiring harness, and bung for installing the sensor. Depending upon your resources most installations take less than two hours. The kit includes a detailed installation and instruction manual.
 - The Boost Control version adds a boost sensor and a boost control solenoid.
 - The Dual Temp version adds a boost sensor and 2 temp sending units.

A pre-wired snowmobile harness exchange is available for the dual temperature version.

A Tach adaptor is required on some units utilizing DIS ignition (distributorless ignition system) and no CAM sensor. Eg: Nytro requires an adaptor, Apex does not require an adaptor.

MPI’s new Nytro Exhaust System is  two versions of the RX-1 lightweight exhaust system. 

11dB Louder with an 11lbs savings

The High Performance MPI Nytro Exhaust System saves weight but increases dB levels. The new exhaust system weighs just 4.75 pounds, with the OEM system weighing over 17 pounds. It was designed for use on Stock and Supercharged units. As this system has significantly less backpressure than the OEM system, Turbo should consult their kit manufacturers, as the increased flow and reduced backpressure will likely be detrimental to a turbo's performance. The system is made of 100% stainless steel and exits through the stock cowling behind the seat. The unit includes a billet aluminum tip.

FEATURES:
 - 100% 304 Stainless Steel Construction (including brackets & internals)
 - Complete Unit Weighs less than 5 pounds
 - Billet Aluminum Tip
 - Mathematically designed "Quiet Core" inside the Muffler to reduce noise, not flow.
 - 100% TIG Welded
 - Increased Exhaust Flow
 - PLEASE NOTE: This unit is louder than OEM, but is not ear piercing.

MPI’s newest add on for the FX-Nytro Supercharger Kit. Works on all 2008+ Nytro models, including MTX, RT, RTX, XTX.

High Performance MPI Nytro Cold Air Supercharger Intake fits conveniently under the hood. In extreme circumstances the unit may be routed through the hood, but testing has shown that simply rerouting the intake to the protected area over the clutches is sufficient to provide good clean dry cold air. The kit is easy to install, but does require that you remove your intercooler to access the supercharger inlet. A template is included to drill a hole in the left side bulkhead (testing shows no effect to structural rigidity of the bulkhead. Includes Fabricated mandrel bent 2.5" aluminum air tube, new filter and all hardware required for installation.

FEATURES:
 - 100% 6061 Aluminum Construction
 - Complete Unit Weighs less than 1 pound
 - New Mesh Filter included
 - Testing shows this kit ADDS 1 TO 2 POUNDS OF BOOST when working the unit hard.
 - 100% TIG Welded
 - Increased Air Flow

Please note: When using the hardened stud you must allow the motor to reach at least 130deg of water temperature before full throttle operation.

 FEATURES:
 - 120 ksi hardened ARP studs
 - Nytro kit includes hardened 12pt nuts and washers
 - 10mm studs.

12mm studs are not appropriate because the block will not support the thinner wall of the larger hole.

If installing the kit on a generic turbo kit, 2 different weldments are available. One is flat and the other is designed to be installed on a 5" radius (or smaller).

If you are planning to weld your own weldment on an older MPI kit, we will provide you the weldment at no additional charge!

FEATURES:
 - 100% Billet Delta Pressure Valve. Double sided diaphragm valve with 2 control hoses.
 - Plumbing includes all fitting and manifolds required to connect the unused high flow vacuum ports on the OE throttle bodies.
 - Springs are available in 5psi, 10psi and 15 psi increments. Valve come with a 10psi spring.
 - The spring pressure is simply the minimum boost value that the valve can boost control at if your are using MPI's electronic boost controller.

This kit can be used with or without the OEM radiator. This makes it possible to shed even more weight from the snowmobile while still enhancing the overall cooling system. This is no little cooler. The actual extrusion measures just over 8 feet long. YES!  E I G H T  FEET. Compare this to the OE tunnel cooler that isn't even 2 feet long!!

Performance improvements are HUGE! Typically 60 degrees cooler with our tunnel cooler and the OE Radiator. Typically 40 degrees cooler with our cooler only (that's you eliminating the OE radiator and OE tunnel cooler).

•  Our XTX Nytro (stock radiator and No OEM Tunnel cooler) ran typical temps over 200deg. WITH OUR NEW COOLER AND THE OE RADIATOR our max temps are 150deg and 110deg in the powder (actually to cool). We are going to pull the OE cooler on this unit.

• Our 2010 MTX Special Addition (stock radiator and OEM tunnel cooler) ran typical temps close to 200deg. With our new cooler only (deleted the radiator), our max temps are 160deg. The sled without the radiator actually idles cooler because without the sled moving, the OE radiator is actually adding heat.
  
  FEATURES:
   - Best Heat Exchanger Design Available. 8 feet in length!!!
   - 100% Tig Welded & Pressure Tested
   - Works with Stock and most Aftermarket Exhaust Systems
   - Includes Hoses, Clamps & Rivets. Everything required.

The Radiator delete kit includes a degas bottle to help keep the air out of the system and provide a location for filling. It uses the OE Yamaha radiator cap.
