Stage 1 Torque

Stage 1 (120 BHP | 270 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 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 1.6 D much more fun to drive.

Most customers also see an economy gain during normal driving conditions when running our Stage 1 remap. For best results remember to carry out regular services to keep the oil clean, the fuel and air filters need to be regularly changed to get the best out of your 1.6 HDI engine.

Our software is custom written in house and only available from HDI Tuning or one of our representatives. All 1.6 TDCI software was developed on our own 1.6 TDCI fiesta test car which was great for perfecting the Stage 1 remap and also developing the stage 3 setups which are very popular.

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 2

On the 1.6 90 model we generally skip the stage 2 step. The reasons for this are because the turbo is very small and pushing it too hard can result in boost instability making the car not so good to drive. A Stage 3 remap uses higher flowing injectors and a larger VNT turbo from the 110 BHP model.

Note: In Scandinavian countries there are some 90 BHP models fitted with the 110 injectors and turbo, this means you can jump straight to the stage 3 remap.

Stage 3 – Option 1 (145 BHP | 290 Nm)

For the HDI tuning stage 3 upgrade we need to fit the turbo and the injectors from the 1.6 16V 110 model. The turbo required is the Garrett GT1544V, this is a VNT turbo instead of a waste gated turbo. The turbo will provide perfectly stable boost within the safe limits of the turbo charger.

HDI Tuning are the only company able to offer remapped software with full VNT control. Others will try, but they will be unable to gain full control of the turbo and this will result in unstable turbo pressure or even turbo failure. Our remap on the other hand will offer excellent turbo reliability by keeping turbo pressure well within safe levels and by not allowing the boost pressure to spike (over boost).

The injectors must also be upgraded. Here we need to choose the correct part number so that the correction codes can be programmed in to the ECU.

0445110239 should be upgraded to 0445110259

0445110311 do not need to be upgraded as they work well at 145 BHP, but if you want to upgrade you can use 0445110297. 0445110353 is also an option in place of the 311 injector, this comes only on newer ford models.

If you use an injector which does not have the same length of correction code the vehicle will still run ok after being remapped to account for the calibration, however you won’t be able to add the correction code. Over time, the ECU will automatically adjust to account for the correction.

All other hardware on the 90 engine is the same as on the 110 engine, so we won’t need to change any other parts.

Some people choose to run this remap with an EGR blanking plate, this is only acceptable for off road use as it is not road legal.

We put together a full fitment guide for the GT15 turbo, please see here.

Stage 3 – Option 2 (155 BHP | 320 Nm)

We also have another option for a turbo and injector upgrade, however this upgrade is not such a direct fit, but is well worth the extra work. 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 full fitment guide.

Price:

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.

Please see here for the full fitment guide.

Price:

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 injectors
  • The clutch will need to be upgraded to a full stage 3 ceramic paddle clutch.

Air Doser Delete

The butterfly/throttle valve 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.

Price:

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

Programming Methods – OBD programming or Bench Programming

There are two variants of the 1.6 EDC16 ECU, EDC16C3 and EDC16C34. The C3 ECU has a 1MB flash whilst the C34 has a 2MB flash.

Recommended programming method:

Program over OBD using the Dimsport MyGenius standalone tool

blank

The Dimsport MyGenius tool is the safest, easiest and most reliable way to program your ECU from home. Simply connect to the OBD port and let the tool do the work, no need to remove your ECU or bench program for most ECU types. For more information have a read here

Programming via OBD EDC16C34

  • Obtain a suitable programming tool; we recommend to use Dimsport MyGenius, you can also use Kess V2.
  • Install the tool to a reliable laptop.
  • Connect to the OBD port of your car, make sure you have backup chargers to the vehicle battery and the laptop battery.
  • ID the ECU and then take a read of the ECUs flash memory.
  • Email the software to remap@hdi-tuning.co.uk along with a description of the remap you require.
  • Send payment through our webshop.
  • We will modify the software and send back to you. This normally takes less than 2 to 3 hours during working days.
  • Using the same tool, ID then write to the ECU. This will overwrite the ECUs flash memory, it’s important not to interrupt the process. If you encounter any problems we can fix the ECU for you so there’s absolutely nothing to worry about.
  • Let your engine warm up and then take the car for a spin, enjoy the extra power!

Programming via BDM100 EDC16C3 & EDC16C34

  • Order a suitable tool such as Kess KTAG or BDM100.
  • Install the tool to a reliable laptop.
  • The ECU must be removed from the vehicle, and then the tabs on the lid can be carefully pried open and the casing of the ECU removed.
  • Using a pogo spring probe connect to the ECU board, power the ECU to the ECU connector plugs as described by your programming tool.
  • ID the ECU and then take a read of the ECUs memories for a backup (please save separately, and not as a combined file). For EDC16C3 the performance maps are in the 1MB flash. For EDC16C34 the performance maps are stored in the 2MB flash memory.
  • Send payment through our webshop.
  • We will modify the software and send back to you. This normally takes less than 2 to 3 hours during working days.
  • Using the same tool, ID then write to the ECU. This will overwrite the ECUs memory, it’s important not to interrupt the process. If you encounter any problems we can fix the ECU for you so there’s absolutely nothing to worry about (You can always repair an ECU if you take a full BDM backup of all memories).
  • Straighten the lid on the ECU and seal with a little silicone.
  • Refit the ECU and start the engine.
  • Let your engine warm up and then take the car for a spin, enjoy the extra power!
