TVS custom ECU software solutions for the EA855 2.5TFSI EVO are divided into different performance levels, supporting various 99ron and suitable for both with or without any hardware modifications.
At this stage*, no hardware is required** although an upgraded air intake may achieve slightly higher figures.

Figures maximum values measured on a car using 99ron fuel. Please check the fuel you use, many “premium” fuels are below this rating and will can cause problems when tuning.
*TVS ECU tuning stages work slightly differently to what we are used to. Please note these figures are advertised as “stage 2” by TVS’ website.
** While no hardware is required, TVS TCU software is recommended to run this torque level on the DQ500.

Features and Options:

Temperature Protection
Next to increased performance, TVS enhanced engine cooling and oil temperature management keeps your engine within optimal and safe temperature limits for maximum performance, durability and reliability!

Improved Fuel Efficiency
Besides increasing performance, TVS is always focussing on several parameters related to fuel economy, especially while city driving or highway cruising. Depending on several factors such as driving style and fuel quality, improved fuel economy may be achieved.

Vehicle Speed Limiter
TVS is able to adjust or remove the vehicle speed limiter from your vehicle to any desired value.

Engine Rev Limiter
TVS is able to adjust or remove the engine speed limiter from your engine to any desired value.

Motorsport (Hard Cut) Rev Limiter
Most factory vehicles limit the engine power output before hitting the actual (hard) rev limit by closing the throttle valve. TVS Motorsport REV limiter allows to reach the actual rev limit without prelimiting the engine power output first. This way all the engine power stays available up to the actual rev limit which allows better acceleration and a true motorsport experience.

Lambda / O2 delete (decat)
When installing a decat downpipe it is important to carefully recalibrate the ECU software and optionally disable the function of the second lambda sensor located after the removed catalyst.

Exhaust Crackle / Pops & Bangs
For various gasoline ECU’s TVS developed exhaust crackle sound software also known as “Pops & Bangs”. This feature will add an outstanding crackle to your exhaust sound after lifting off the throttle, decelerating or while free revving at standstill.
Please note that we do not recommend using this feature on a stock downpipe or sports cat.

Start/Stop OFF
For those of you that hate the Start/Stop technology TVS can fully deactivate this feature within the ECU software. For some models, reversing of the functionality is also available.
