We've added two major capabilities to The Torque Lab: diesel ECU remapping and European car tuning. This means we can now tune virtually any vehicle that comes through the door - Japanese, European, diesel, petrol, classic, and modern.
What's new
We've invested in professional ECU reading and flashing hardware that covers over 2,800 vehicle applications. This gives us access to factory ECU calibration data across the full range of diesel and European platforms - something that previously required sending vehicles elsewhere.
Combined with our Mainline hub dyno, every tune is custom-calibrated and verified with real data. No generic files, no guesswork.
Diesel tuning
We now offer DPF-safe diesel ECU remapping for the full range of diesel vehicles in New Zealand:
- Utes - Ford Ranger, Toyota Hilux, Nissan Navara, Isuzu D-Max, Mazda BT-50, Mitsubishi Triton, Volkswagen Amarok
- SUVs and 4WDs - Toyota Prado, Toyota Fortuner, Mitsubishi Pajero Sport, Nissan Patrol, Isuzu MU-X, Ford Everest
- European diesel - BMW 320d/520d, Audi Q5/Q7 TDI, VW Tiguan/Touareg TDI, Mercedes C220d/GLC
- Light commercial - Toyota Hiace, Ford Transit, Mercedes Sprinter
- Agricultural and marine - tractors, harvesters, and marine diesel engines
Typical gains on a common rail diesel ute are 20-30% more power and 25-35% more torque. Fuel economy improvements of 5-15% are normal under regular driving conditions. Every tune is DPF-safe and emissions compliant - we do not remove, bypass, or disable any emissions equipment.
For 4WDs and vehicles that can't run on a traditional dyno, our ECU file calibration service means we can still deliver a precision tune without the dyno. We read the factory ECU, calibrate the file using proven data from your platform, and flash the optimised calibration back.
European car tuning
We now remap factory ECUs on the full European range:
- BMW - 1/2/3/4/5 Series, M Sport, X range. N20, N55, B48, B58 engines.
- Audi - A3, A4, A5, A6, S3, RS3, Q5, Q7. EA888 and TDI platforms.
- Volkswagen - Golf GTI, Golf R, Polo GTI, Tiguan, Amarok. EA888 platform.
- Mercedes-Benz - A-Class, C-Class, E-Class, AMG, GLC, Sprinter.
- Others - Volvo, Skoda, SEAT, MINI Cooper S/JCW.
European factory ECUs are heavily detuned for global markets. The same Golf GTI engine ships to 30+ countries with identical hardware but conservative software calibrated for the worst-case fuel and climate. In New Zealand, with 98 octane fuel, there's significant performance left on the table.
A factory ECU remap on a Golf GTI typically adds 40-55 kW. A Golf R sees 50-65 kW. BMW 3 Series turbo models gain 30-40%. Every remap is verified on our Mainline hub dyno with before-and-after data.
How it works
The process is straightforward:
- We read the factory ECU calibration via the OBD port or bench flash
- The calibration data is modified - fuel maps, boost targets, ignition timing, torque limiters
- The modified calibration is flashed back to the factory ECU
- The tune is verified on the Mainline hub dyno with real-time data logging
- You leave with before-and-after dyno sheets showing exactly what changed
No aftermarket boxes, no piggyback devices, no tuning modules. Just a refined factory calibration that unlocks what the hardware was always capable of.
