Fiat 500 / 595 / 695 1.6 JTDM Stage 1 Remap
On Fiat 500 / 595 / 695 1.6 JTDM 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. 1.6 JTDM engines with 105–120 bhp reach 135–155 bhp with a Stage 1 remap; the largest gain is +35 bhp (500 1.6 JTDM 120hp). 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 Fiat / Alfa Romeo 1.6 and 2.0 Multijet (JTDM)
The 1.6 and 2.0 Multijet power the Fiat Tipo, Bravo, Doblo, 500X, Alfa Romeo Giulietta, 159, Jeep Renegade and Compass, from 105 to 170 hp. They are Fiat's own modern common-rail engines, not PSA-derived.
How a Stage 1 remap works on the Fiat 500 / 595 / 695 1.6 JTDM
Stage 1 recalibrates rail pressure, injection duration, boost and the torque limiter. A full mid-range torque gain results; on common versions such as the Tipo 1.6 Multijet overtaking confidence improves clearly. On DCT automatic cars the torque limit is respected.
Pre-remap checklist
- DPF load and regeneration history.
- EGR valve and cooler.
- Boost leaks and intercooler hoses.
- Dual-mass flywheel and clutch.
