Charge Pressure Adaption:

Adaption of maximum charging pressure occurs continuously during normal driving. If the ECM is replaced or other steps are taken which affect the level of adaptation, a system adaptation may be conducted as follows in order to speed adaptation and thereby achieve maximum performance more rapidly.

Caution
The engine should be thoroughly warmed-up. The base charging pressure should be adjusted to the right value. Use good-quality, high octane fuel.

Vehicles with a manual gearbox
Accelerate at full-throttle in as high a gear as possible, from approx. 2000 rpm up to 3500 rpm.

Because the minimum time for passage of adaptation area (2750-3250 rpm) should be longer than 3 seconds, it is suitable to perform the adaption on an upward incline.

The procedure is repeated until the maximum nominal charging pressure, with regard to fuel quality, etc., is achieved.

Vehicles with automatic transmission
Accelerate with as much throttle as possible without the Kickdown function being activated, from approx. 3000 rpm up to 4500 rpm.

Because the minimum time for passage of the adaptation area (3750A250 rpm) should be longer than 3 seconds, it is suitable to perform the adaptation on an upward incline.

The procedure is repeated until the maximum nominal charging pressure, with regard to fuel quality, etc., is achieved.



NOTE:
If repeated pressure monitor operation has been caused by excessive charging pressure (such as due to a defective solenoid valve), maximum negative adaption will be obtained. This means that the normal maximum charging pressure will not be attained. To attain maximum charging pressure, disconnect and reconnect the control module and then carry out adaption.
