Mistral Fuel Injection Trim Module (MG-V-TWINBOOST12)

Mistral Fuel Injection Trim Module

Mistral Fuel Injection Trim Module

Operating on a similar design to the FatDuc O2 emulator, this non-adjustable Fuel Injection trim module is designed specifically to improve fueling on Moto Guzzi 1100/1200cc bikes with aftermarket Mistral or Agostini slip-on exhausts fittted. 

For any of the following bikes with slip-on exhausts:

  • '08-'17 Stelvio 1200 8V NTX-ABS
  • '06-'16 Norge 1200 
  • '05-'09 Griso 1100
  • '10-'17 Griso 1200 8V
  • '05-'08 Breva 1100
  • '07-'08 Sport 1200 Breva
  • '06-'11 California 1100

This device ensures improved fuel injection performance with benefits include less popping during deceleration; better throttle response, providing a reduction in the "on/off" effect between throttle closed and throttle open positions, and improved acceleration; increased torque in the low and middle rpm ranges, Also improves vehicle operation at lower engine speeds and can lead to reduced fuel consumption.

Direct match wire connectors make installation "plug and play" with no additional modification required.

Mistral also lists this module for the following 750cc models, though due to the different fueling requirements, we expect it will be less effective:

  • V7 Classic
  • '11-'12 V7 Racer
