Performing a Saab 9000 Trionic boost adaptation run
This information is taken from the Saab technical documentation on the Trionic system. The original document describing the Trionic system is available at the Townsend Imports site.
The Saab Trionic engine management system continuously adapts the maximum turbo boost level during normal driving. However, after replacement of parts of the system affecting the boost level, or disconnection or replacement of the Trionic control unit, a large amount of adaptation will be required, and the adaptation can be accelerated by the following procedure. This procedure may also be of benefit if it is suspected that the Trionic system has mis-adapted due to a faulty component (e.g. solenoid valve) or the use of an inferior fuel. If the system is suspected to be severely mis-adapted, it is probably best to disconnect the control module for a few minutes, then reconnect and start afresh. Do this by either disconnecting the large multiway cable to the unit or by removing the fuse in the fuse box under the dashboard.
The procedure is slightly different depending on whether the car has automatic or manual transmission fitted. The procedure for both types of transmission is provided. I have only tested the procedure for manual transmission, as I have never owned (and probably never will own) an automatic 9000.
I had to power down and reconnect the Trionic system on my '96 Aero after replacing a faulty oxygen sensor that left the "check engine" light illuminated. After performing the procedure below, the car definitely ran more smoothly and was more powerful than ever before (this must have been partly due to the new sensor, though).
