Chiptuning Saab 9-3 2.0 T – Trionic 8 ECU – 205 HP / 339 Nm
Share
A Saab 9-3 with a 2.0 T petrol turbo engine arrived at our workshop with a claimed power output of 170 hp. A dyno reading showed 165 hp, which is typical for older models.
After individually tuning the Trionic 8 controller, we achieved 205 HP and 339 Nm , maintaining full safety of the engine and the supercharging system.
The modification significantly improved the throttle response, flexibility and operating character of the unit – without the risk of overloading the components.
Customer's car - initial state
-
Model: Saab 9-3 2.0 T
-
Engine: 2.0 Turbo Petrol (B207)
-
ECU: Trionic 8 sw 55535227
-

-
Customer Goal: Recover lost power and improve mid-range acceleration
Modification process – diagnostics, reading, tuning
Before starting the modification, we performed ECU diagnostics and baseline measurements on Dynomax and Dynomet dynamometers to verify the condition of the engine and boost control systems.
The Trionic 8 controller was read via the OBD connector and analyzed for:
-
ignition map,
-
fuel doses and boost pressure,
-
torque limiters and thermal protection.
Based on this, we have prepared an individual Stage 1 file , ensuring a safe increase in power and torque.
The entire process—from reading to final writing—took about 30–40 minutes .
The end result – increased power and torque
| Parameter | Before modification | After modification | Increase |
|---|---|---|---|
| Power (hp) | 165 hp | 205 hp | +40 hp |
| Torque (Nm) | 300 Nm | 339 Nm | +39 Nm |
After the modification, the Saab gained much better flexibility – torque is available from 2,000 rpm, and the response to the throttle has become immediate.
The engine runs smoothly and boost builds steadily throughout the entire rev range – a perfect compromise between dynamics and durability.
