Fiat Doblo 1.3 JTD 85hp

Stage 1 chip tuning for the Fiat Doblo 1.3 JTD 85hp increases power from 85 to 113 hp (+28 hp, +33%) and torque from 190 to 240 Nm. Turbocharged diesel engines offer the greatest chip tuning potential – optimizing boost pressure and injection maps delivers significant gains in both power and torque from low RPM.

The remap is performed on the Marelli MJD6F3 ECU (engine code 223A9000) via the OBD2 diagnostic port – no ECU removal required. We use Alientech KESSv2, Bitbox Bitbox, ByteShooter Toolbox and other professional tools. Results are verified with a dynamometer measurement.

Under normal driving conditions, chip tuning a turbocharged diesel can reduce fuel consumption – in Eco mode, savings reach up to 0.5 l/100 km thanks to more efficient turbo operation and optimized injection.

In addition to Stage 1, we offer the following services for the Fiat Doblo 1.3 JTD 85hp: DPF diagnostics and maintenance, EGR valve diagnostics. All work is performed using professional equipment.

If desired, the Fiat Doblo 1.3 JTD 85hp can be upgraded to Stage 2 – a deeper optimization delivering even greater power and torque gains. Stage 2 involves advanced ECU calibration taking into account exhaust system and intercooler modifications. Contact us for a free consultation to evaluate Stage 2 potential for your specific vehicle.

Every vehicle undergoes full diagnostics before and after the remap. We keep a backup of the original ECU calibration and guarantee the option to revert to stock settings at any time. JVK PRO is a professional chip tuning service in Riga with 16 years of experience.
