Tune Boxes FAQ

What is meant by tuning...?

Tuning nowadays means electronically releasing power that has been limited by the manufacturer. You can do this by means of Chip tuning, EOBD tuning or a tuning box (also called by-pass-tuning).

Why would you want to tune a car...?

The performance of your car has been limited by the manufacturer in the car factory. This is done, because the car manufacturer has to comply with certain emission requirements, or because the manufacturer wants to market one model of engine in multiple power versions. EPC makes use of these ‘hidden’ reserves and releases them.

Will my diesel particulate filter become blocked if I tune my vehicle...?

EPC makes use of individually adjusted tuning electronics, developed and tested on our dynamo-meter, to ensure that in the so-called full-load ranges (the rpm at which your vehicle must provide the highest torque) there will be no unnecessary soot development. Therefore, EPC tuning for vehicles from the year of manufacture 2008 has been developed with 2-channel or 3-channel technology. (2 and 3 channel hyperlink to explanation about 2-channel and 3-channel explanation).

Will my vehicle use less fuel after tuning?

It has been proven that if you increase your engine efficiency in a specific speed range, and you shift gears in that speed range, your fuel consumption will decrease. In other words: if you had 250 Nm torque at 2000 rpm before tuning, and you have, after tuning, 250 Nm torque at 1800 rpm, AND you adjust your gear switching behaviour in line with this, your vehicle will become more fuel efficient. However, if you use your right foot after tuning, your fuel efficiency will become undone.

Will tuning shorten the life of my engine?

After tuning, a heavier load will be put both on the engine and the power train. Because manufacturers usually design mechanical parts with excess dimensioning properties, we can safely tune your vehicle within safe margins. These margins are tested on the dynamo-meter, after which they are programmed into the software by us. According to an unwritten rule, one should never exceed 18 – 20% as compared to the performance specified by the manufacturer. If you want to go beyond that, you will have to make modifications to certain mechanical components, such as the gearbox, the clutch, the brakes, the bearings, the turbo-compressor, etc.

What does 1-channel technology mean?

1-channel technology means that tuning is realised by the adaptation of 1 signal. EPC tuning works with rail pressure signals, which will see to it that power is released within certain limits. 1-channel tuning can be applied to vehicles up to the year of manufacture 2008.What does 2-channel technology mean?2-channel technology means that the tuning is realised by the adaptation of 2 signals.  Because of stricter emission requirements it is no longer possible to release power with a 1-channel tuning. EPC tuning, therefore, uses the rail pressure signals combined with the turbo pressure signals, which will see to it that power is released within certain limits. 2-channel tuning is applied to vehicles from the year of manufacture 2008.

What does 3-channel technology mean?

3-channel technology means that the tuning is realised by the adaptation of 3 signals.  Because of stricter emission requirements and because of a tuning protection installed by the manufacturer, it is no longer possible to release power with a 1-channel tuning or even 2-channel tuning. EPC tuning, therefore, uses the rail pressure signals combined with the turbo pressure signals and boost control signals, which will see to it that power is released within certain limits. 3-channel tuning is applied to vehicles from the year of manufacture 2010/2011.

Will I lose the manufacturer’s warranty after tuning?

Every adjustment to a vehicle that is not ratified by the manufacturer will result in the manufacturer’s warranty becoming annulled. EPC tuning has been manufactured with automotive connectors, for easy assembly and disassembly.
