  • How Remote Tuning Works

    How Remote Tuning Works

    1 - Order & Ship

    Purchase your RTD4 package here. We will ship the hardware interface directly to your door.

    2 - Read & Sync

    Plug the RTD4 into your vehicles OBD port. Open the TDN smartphone app via Bluetooth, read your stock file, do a datalog and input your current vehicle modifications.

    3 - MSD Calibration

    Our expert calibrations team receives your file, reviews your mod list, and assigns your custom map to your account.

    4 - Flash & Drive

    Open the app, download your newly assigned MSD calibration, flash it straight to your vehicle's PCM, and enjoy the drive!


    Please Note: 

    A stable data connection is required while syncing files via the TDN application. 

    Ensure your phone battery is charged and car electronics are turned off (fans, lights, radio) while flashing.

  • Safety Information

    Beware: All ECU calibrations are not created equally...                         

    There are many ways to calibrate  a modern vehicles ECU but the sad fact remains that a huge percentage of the tunes we see have had all the safety strategies and drive logic features removed from them. These modern Bosch PCM's have exceptional engine control strategies built into them and these systems are a key reason that as standard, these vehicles drive so amazingly well. Smooth, linear and powerful to the rev limiter. And safe too... the protection strategies are incredibly complex and work alongside a very comprehensive torque model in order to deliver what the driver asks, but keep the engine in one piece should things go wrong.                       

    To  recalibrate a PCM properly, from scratch as we do, takes many hundreds of hours of development on our in house dyno. But the results are worthwhile.
                                     
    For further information on how the PCM safety strategies work, why not heard our to our calibrators technical blogs on the subject:

Direnza Ford Focus MK4 ST – MVT Front Mount Intercooler 2018 – Present

Direnza

                          Provided performance gains of +21.8bhp / 16.8nmIntake Temperatures by 10°C116.7°c Temperature dropDesigned using state of the art 3D CAD and CFD modellingDirect replacement for the original IntercoolerTIG welded for maximum strength and durabilityMVT technology designed by Direnza offers greater intercooler efficiency in comparison to other aftermarket alternatives. This is achieved through the use of carefully placed vanes in the end tank which evenly distribute air across the entire core. Ensuring the full surface area of the intercooler core is optimised to cool your charged air, resulting in more power.Test car: Ford Focus MK4 ST 291.4hp / 429.2nmPut through its paces on a state-of-the-art Maha MSR 500 Dyno, our Multi Vane Technology Intercooler for the Focus ST yielded some highly impressive results.After installing our revolutionary MVT Intercooler, engine performance improved significantly. With the Focus now producing 313.2hp & 445.9nm of torque, that’s an increase of +21.8hp & 16.7nm of torque without any additional tuning.What’s more impressive is the cooling power of MVT. Using sophisticated data logging software, we measured intercooler inlet temperatures at 140.1°c. The stock intercooler performed well, reducing this to 63.9°c at the Intercooler outlet. However, with MVT installed, outlet temps were reduced an additional 40.5°c down to 23.4°c! That’s an overall temperature drop of 116.7°c. Thus, providing huge tuning potential and greater reliability when combined with a remap & supporting modifications. The perfect addition to any track or modified road car!  Click here for the fitting guide

Forge Ford Focus ST MK4 280 Induction Kit

Forge

Gains of up to 17BHPBlack powder coating for ultimate protection and durability.  Forge Pleated performance air filter No engine management check lights (EML) Increased air flowLifetime warrantyThis FMINDK37 is the cold air intake system for the Ford Focus ST Mk4 and has been designed to improve airflow in several key ways. It routes the air more directly into the vehicles engine, using an increased diameter CNC mandrel bent alloy pipe. This induction system also improves the airflow by adding our Forge high flow pleated air filter, in place of the more restrictive factory air filter.The choice of air filter was made after many rolling road sessions and data logging test drives. As we have seen many times before with Ford power plants our Forge Hi-Flow pleated air filters gave the best results. The construction and build quality of the filter oozes superior quality and enhances the ST 280s engine bay. Forge Hi-Flow filters are made using a premium quality, high flow, synthetic nanofiber filtration media which is pleated to maximise surface area and in turn increase air flow.The CAD designed, laser cut, and precision folded heat shield is designed to form a barrier between the air filter and radiant heat from the engine. It also helps duct the cold air to the air filter, to help preserve low intake temperatures. The heat shield is designed to incorporate the OEM air duct and fits directly to the standard factory air box mounting points and rubbers without the need for modification.The diameters on this air intake have been carefully tuned to provide exactly the correct quantity of air flow into the turbo charger, ensuring consistent power gains throughout the rev range without any loss of low-end torque, increasing power and enhancing induction acoustics for added character and excitement.We used Performance Remap in Gloucester with their VTEC 4 wheel-drive dynamometer, this was to ensure all our data has been collated independently, The results below speak for themselves, Testing and development took place on a MK4 ST 280 with Mountune STAGE 1 software. The stock dyno pulls gave a base figure of 307 BHP at 5458 RPM, from simply swapping out to the Forge Motorsport Intake in the matter of around 30 minutes, yields of over 17 BHP were achieved.When studying the dyno graph below the peak torque figure does appear to be 5NM below the stock airbox figure however please take note of the 17NM gained from the Forge Motorsport induction kit throughout the midrange.With both the BHP and torque figures held higher throughout the rev range your engine will definitely have the edge and feel more responsive when pushed to its limits. As with all Forge Motorsport products we offer a no quibble lifetime guarantee on all parts of this kit excluding the filter.
