About the remap

Stage 1 chip tuning for the Volvo Trucks FH 12 420hp increases power from 420 to 503 hp (+83 hp, +20%) and torque from 2000 to 2450 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 C ECU (engine code D12D) via the OBD2 diagnostic port – no ECU removal required. Results are verified with a dynamometer measurement.

In addition to Stage 1, we offer the following services for the Volvo Trucks FH 12 420hp: DPF diagnostics and maintenance, EGR valve diagnostics. All work is performed using professional equipment.

If desired, the Volvo Trucks FH 12 420hp 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.

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.
