ENGINE (4G6) – CONTROL SYSTEM (6 M/T)110
1. Supercharging pressure control
The maximum torque has been increased, compared to the 4G63DOHCT/C engine in the current Lancer Evolution VIII, by
installing an additional wastegate solenoid valve (increased from 1 to 2 valves).
By adding a parallel No.2 wastegate solenoid valve to the previous system, provides extra relief capacity for the pressure
applied to the wastegate actuator thus increasing the range of supercharging pressure..
The engine ECU raises the supercharging pressure even further, thus raising the maximum torque, by driving the No.2
wastegate solenoid valve when the engine approaches maximum torque.
The No.1 wastegate solenoid valve is essentially controlled in the same way as previously.

Precautions to be taken when servicing vehicles with seatbelts fitted with SRS Airbag and Pretensioners
Precautions
1. Incorrect inspection or servicing of SRS airbag and pretensioner fitted seatbelt parts, as well as any related
components, could lead to major damage or nonoperation as a result of sudden, unintentional operation of SRS
airbag and pretensioner fitted seatbelts (incorrect deployment).
2.In cases where heating from painting processes occurs, the SRSECU, driver side airbag module, passenger side
airbag module, pretensioner fitted seatbelts, and cross springs, should be removed.
• 93°C and above: SRSECU, driver side airbag module, passenger side airbag module, cross springs
• 90°C and above: pretensioner fitted seatbelts3.Inspections and servicing of SRS airbag and pretensioner fitted seatbelt parts and any related components must,
without fail, be done by a Mitsubishi Motors authorized dealer.
4. Inspections and servicing of SRS airbag and pretensioner fitted seatbelt parts and any related components must be
done paying scrupulous attention to the relevant service manual (particularly in the case of Group 52B – SRS
airbags).
