Product Information

Cutting Edge Digital Tuning Technology

The CRTD4 SENT Petrol Tuning Box from TDI Tuning for the Audi A8 3.0 TFSI Quattro 335 BHP / 340 PS / 250 KW / 500 NM / 369 LBFT  is at the cutting edge of digital tuning box technology with the capacity to remap brand new digital sensor based engines from Audi and Porsche. Powered by a powerful 80 MHz ARM microprocessor the CRTD4 remaps vehicle performance moment by moment based on digital data received via the engine sensor interface harness. The engine fuelling profile of the vehicle is then remapped to increase power and torque whilst improving power delivery, eliminating acceleration flat spots in specific gear RPM ranges, and creating a smoother and more responsive drive experience. For your engine, available power will be increased by 64 BHP and available torque will be increased by 65 Nm.

 

A Revolution In Vehicle Performance Tuning

For domestic vehicle owners the CRTD4 SENT is a flexible tuning solution when compared to traditional ECU Remapping, allowing owners to adjust power and torque output via 7 operating mode settings ranging from maximum economy up to maximum power delivery, ideal for switching between everyday driving and long-haul trips. On top of this the ability to be reprogrammed for over 99% of modern turbo diesel and petrol vehicles, unlike a remap, also represents great value with the cost of a reprogram starting at nearly a ¼ of the cost of a brand new product.

Improved Fuel Efficiency:
The TDI-Tuning box can improve fuel efficiency by up to 20%. This fuel efficiency improvement is down to your own individual driving style.
5 Year Product Warranty:
The TDI-Tuning Box comes with a 5-year product warranty. This is a fully comprehensive product warranty. If anything goes wrong with your TDI-Tuning Box, we will fix it or replace it free of charge.
Traceless Removal:
The TDI-Tuning Box is traceless once removed from the vehicle. It does not leave a digital or physical trace behind. This is because the tuning box adjusts your engine sensor readings before the ECU (Electronic Control Unit). Please ensure you remove your tuning box before inspection.

    Warm-Up Timer

    The TDI-Tuning Box comes built in with a 30 second warm up timer. This means the map file will not begin to run until 30 seconds after your engine is turned on. This is to protect your engine, primarily for cold engine starts. If you would like to increase, or decrease this map timer, you can adjust it using the TDI-Tuning App.
