1.6 D 16V 107 BHP Bosch EDC16C3/34

The Mazda 3 1.6D 16V 107 BHP engine responds extremely well to a stage 1 remap. Not only do you get a massive amount of torque, you also get lots of top end power so you can keep pulling all the way through the rev range. Our online remapping service can provide a custom written tuning file with all parameters optimised to the Volvo ECU software, the software is written in house from your original ECU software.

Stage 1 – DPF safe (138 BHP | 280 Nm)

Our stage 1 remap provides constant and increased torque through the entire rev range whilst remaining well within the safe limits of your clutch, dual mass flywheel and turbo charger. The torque delivery will be smooth and stable and it won’t drop off in the higher RPMs like the stock mapping, making your Mazda 3 1.6D much more fun to drive.

We’ve designed our stage 1 remap to run cleanly and in unison with the DPF system, this means that there is no increased risk of clogging the DPF filter as long as regular long journeys are undertaken by the vehicle.

Most customers also see a small economy gain during normal driving conditions.

You can program the ECU yourself using our online remapping service. For this we recommend to use the Kess V2 tool. With this tool you can you program directly over the OBD port.

If you prefer to send the ECU to us for the programming work, you can use our postal remap service.

Stage 1 + Full Power Remap (143 BHP | 295 Nm)

The full power stage 1 remap from HDI Tuning will take your Mazda 1.6D 110 to 143BHP and 295Nm. You can run a performance down pipe and exhaust system when using the Stage 1+ Remap.

We’ve developed our 1.6 remaps not only to give optimal performance, but also to remain within the limits of the stock hardware of your vehicle such as the dual mass flywheel and the clutch, and most importantly the turbo.
When a DPF is removed the pressure ratio across the turbine is increased, and hence the spooling characteristics of the turbo charger will be changed significantly. Our stage 1 remap completely re-writes the control parameters of your VNT turbo to suit the change in pressure. This not only enhances the smoothness of your torque curve, it also protects your turbo from over boosting. HDI Tuning’s remaps are the only 1.6 HDI remaps designed to protect your turbo charger.

The Stage 1+ Remap is more aggressive and when used on a vehicle with a particle filter there is an increased risk of clogging, it’s important to do regular long journeys to avoid that risk.

Stage 2

On the 1.6 110 model we generally skip the stage 2 step. The reason for this is so that we don’t over stress the turbo, we like to keep our remaps safe and reliable. Instead, if we want more power we need to fit a larger or stronger turbo charger such as a GTD1244VZ and also a larger intercooler. That’s not to say you won’t get more power if you’re running a Stage 1+ remap with an intercooler and exhaust upgrade, you definitely will, we just won’t push the turbo any harder than the Stage 1+ settings as these have proven to be safe and reliable over many years of testing for a standard GT1544V turbo.

Stage 3 – Option 2 GTD1244VZ (155 BHP | 320 Nm)

We have a great option for a turbo and injector upgrade, this upgrade is almost a direct fit and uses the turbo from the newer 1.6 engine.

The GTD1244VZ uses fourth generation Garrett GTD technology which means earlier spool and better top end power. Another plus is that this turbo fits directly on to the stock exhaust manifold.

To run this remap we also require you to upgrade to the 0445110297 injectors, fit a 3.1 Bar MAP sensor, performance down pipe and an EGR blank (for track use only). It’s well worth while to fit an uprated intercooler, with this you can push for nearer to 160 BHP. Please see here for the GTD12 fitment guide.

Stage 3 – Option 3 (185 BHP | 370 Nm)

The next step up is to build a hybrid GTD12 using a 49mm compressor wheel (please contact for full specifications before building your turbo).

To run this remap we also require you to upgrade to the 0445110297 injectors, fit a 3.1 Bar MAP sensor, performance down pipe and an EGR blank (for track use only). You will also need a large front mount intercooler with a straight through exhaust system of 2.5 inch.

The clutch will need to be upgraded to at least a stage 2 Kevlar clutch, or better is a full stage 3 ceramic paddle clutch.

Stage 4 (205 BHP | 380 Nm)

HDI Tuning have developed a completely custom turbo manifold kit to fit the 1.6 16V engine. The turbo used is a TF035 from a 2.2 Mitsubishi engine with a very modern VNT system. This turbo offers excellent spool and crazy top end power.

Upgrades required:

• TF035 manifold;
• TF035 turbo;
• 3.1 bar or 4 bar MAP sensor;
• Turbo down pipe;
• 2.5 inch exhaust system;
• Large FMIC;
• 0445110297 or 0445110353 injectors;
• The clutch will need to be upgraded to a full stage 3 ceramic paddle clutch.

Air Doser Delete

The butterfly/throttle and intercooler bypass valves in the intake can sometimes go wrong or leak. You can either disconnect it, or make a custom air doser delete pipe (this must have a mount for the boost sensor and the temperature sensor). We can then delete this part through a software remap. This can only be carried out if the DPF system is removed, the intercooler bypass valve works during regeneration modes.

Price:

• £50 for only ADD delete (online remap only), included with any remap if requested.

DPF Delete (off road and track use only)

For vehicles with a DPF fault which will be used for off road or track use only, we can remove all DPF related software, the DPF system must then be emptied out to ensure no further problems. DPF Delete is illegal and should only be used for off road use and for track use. For optimal race performance fit a straight through pipe in its place. You cannot run a remap with DPF Delete software without removing the DPF filter as it will no longer regenerate, hence it will clog. On Mazda 1.6 variants the additive pump must remain connected after DPF delete as a level sensor is present. It is possible to refill the reservoir with diesel.
