10.9. Engine Control Unit (ECU)
The GT3 R is equipped with a Bosch MS 4.0 ECU specially developed for
motorsport applications. The Bosch MS 4.0 can be programmed with
special software. The ECU is programmed exclusively by Porsche
Motorsport. If an engine is overhauled by Porsche Motorsport the ECU
should be delivered with the engine to run them both together on the
dynamometer.
As a safety precaution the ECU should always be disconnected from the
wiring loom and removed from the car if welding work is carried out.
10.9.1. ECU DIAG
The message ‘ECU DIAG’ is displayed in the MoTeC dash when electric
errors (sensors) occur at a specific frequency or are always active. The
message also indicates MS 4.0 system errors.
A special software (Bosch Modas), which can be purchased from Porsche
Motorsport, is required to delete the errors.
10.9.2. MODAS
With the MODAS software various parameters can retrieved from the ECU
and modified.
In addition, errors occurring are saved in an error log that can be
retrieved for analysis.
