Toyota Auris 1.4 D4D 90 HP – EDC17C47 (SW 006943) – Stage 1 – 113 HP / 265 Nm
This project perfectly demonstrates that chip tuning can be effectively and safely performed on almost any vehicle with a turbocharger – even a small, economical diesel like the Toyota Auris 1.4 D4D .
During implementation, we focused on improving flexibility, work culture and dynamics – without overloading the equipment.
The Bosch EDC17C47 (SW 006943) ECU has been individually mapped and optimized in the Stage 1 version, based on measurements from the Dynomax / Dynomet dynamometer.
Parameters and effect of modification
| Parameter | In series | After modification | Increase |
|---|---|---|---|
| Power (hp) | 93 hp | 113 hp | +20 hp |
| Torque (Nm) | 232 Nm | 265 Nm | +33 Nm |
Thanks to seemingly small changes, we have achieved significantly better flexibility and smoother acceleration , especially in the 1800-3000 rpm range, where the car previously lacked "life".
The increased torque allows for a more comfortable ride on the road and lower fuel consumption with a relaxed driving style.
Description of the modification
-
ECU: Bosch EDC17C47 (SW 006943)
-
Scope: Stage 1 – optimization of torque, boost pressure and fuel delivery
-
Reading mode: OBD
-
Dynamometer: Dynomax / Dynomet
-
Completion time: approx. 40 minutes
We prepare each file individually, using professional chip tuning files with full analysis of safety maps.
The modification maintains factory EGT limits, which guarantees the durability of the turbocharger and injection system.
The effect in practice
-
⚙️ Greater flexibility at low and medium speeds
-
🚗 Better driving dynamics and throttle response
-
🔧 Safe, factory-set thermal parameters
-
⛽ Possible fuel consumption reduction by 0.3–0.5 l/100 km
This implementation is an example that chip tuning does not always have to mean extreme power increases – often the most important effect is the comfort and smoothness of driving that the driver experiences every day.
