Hyundai Matrix 1.5 CRDi Stage 1 Remap
On Hyundai Matrix 1.5 CRDi diesel engines a Stage 1 remap recalibrates the fuel quantity, injection timing, boost pressure and torque limiter maps. No hardware is changed and the original software is backed up. The same engine is sold with different stock outputs across generations, so the gain depends on your version.
It depends on the generation and the stock output. 1.5 CRDi engines with 82–110 bhp reach 112–140 bhp with a Stage 1 remap; the largest gain is +30 bhp (1.5 CRDi 82hp). Pick your version in the table below.

GP Power ECU applies the software at its workshop in Hukou, Hsinchu, using EcuPrime-developed files; workshops can also order the file directly.
About the common-rail turbo diesel engine
This vehicle uses a common-rail turbo diesel engine. In this technology fuel is sprayed from a shared high-pressure rail through electronically controlled injectors, and the ECU constantly manages injection quantity, timing and boost pressure.
How a Stage 1 remap works on the Hyundai Matrix 1.5 CRDi
A Stage 1 remap recalibrates injection quantity, rail pressure, boost pressure and torque limiters together. Torque gains are clear on diesels and pull improves at low and mid revs. Smoke, exhaust temperature and turbo speed limits are kept.
Pre-remap checklist
- Injector condition and leak-off test.
- Leaks in the turbo and boost circuit.
- EGR valve and, on DPF cars, the differential pressure sensor.
- Clutch and dual-mass flywheel; the extra torque can cause slipping.
Catalogue figures assume a healthy engine; diagnosis first, then software.
