    Having spent countless development hours on newer engine types and various high power projects since our 2.0TFSI KO4 software was first released, we thought it beneficial to our existing customer base to incorporate some of this new tuning into our production software. Based on both these new tuning developments and customer feedback this tuning update has been developed, tested and is now available through the Revo Dealer Network.


    Stage Overview:


    Stage 1 Performance Software is designed to enhance the performance of an otherwise standard engine. Power, torque, responsiveness and flexibility are all improved while maintaining stock levels of smoothness, reliability and fuel economy. Stage 1 software is suitable for a healthy vehicle with standard components. Stage 1 software is boost, fuelling and timing adjustable allowing the vehicle to be setup to suit the fuel quality, driving conditions and driver preferences.

    Stage 2 Performance Software has been specifically developed to attain the best possible performance from cars with bolt on performance modifications. Stage 2 allows you to run a de-cat or sports cat without getting a ‘CAT Efficiency’ error code or a having CEL (Check Engine Light) come on. It also gives you slightly more flexibility with settings over stage 1 to make the most of the additional potential from the up-rated hardware. Stage 2 software is also boost, fuelling and timing adjustable allowing the vehicle to be setup to suit the fuel quality, driving conditions and driver preferences. 2.0TFSI Stage 2 software is specifically tuned to suit the limitations of the standard high pressure fuel pump and is designed to suit the following hardware upgrades:

    • Turbo Back Exhaust
    • Cold Air Intake
    • FMIC (Recommended but not required)

    Stage 2+ Performance Software has been specifically developed to attain the best possible performance from cars with bolt on performance modifications as per Stage 2 software, however is specific to cars with up-rated high pressure fuel pumps. Power increases depend very much on the hardware, settings and fuel being used. The up-rated fuel pump allows much more power throughout the rev range but specifically in the midrange where the stock pump is insufficient. Stage 2+ software is boost, fuelling and timing adjustable allowing the vehicle to be setup to suit the fuel quality, driving conditions and driver preferences. Hardware requirements are:

    • Turbo Back Exhaust with High Flow CAT or De-CAT
    • Cold Air Intake
    • Up-rated High Pressure Fuel Pump
    • FMIC - Recommended


    Update Overview:

    Increased flexibility of boost adjustment

    A bigger difference in requested boost values between boost setting 6 and 9. Boost setting 9 will ask for much more throughout the midrange than boost setting 6. This allows a greater level of adjustability to suit varying driver preferences; boost 6 giving a much more progressive setup than boost 9. Boost 9 giving a much bigger ‘shove in the back’ at low rpm.

    Increased flexibility of fuelling adjustment
    A wider level of fuelling adjustment allows a greater level of flexibility in varying conditions.

    More efficient temperature correction
    Improved temperature correction for hot running conditions, the higher the temps. the more the ECU will pull back to compensate.

    Fix to prevent incorrectly setup car suffering from power dip in midrange
    Alteration to the way ECU correction effects power delivery if a vehicles settings are incorrect for the operating conditions or fuel quality being used; preventing an excessive dip in midrange typically referred to as a hesitation around 4500-5500rpm.

    Linear Throttle options available for all 2.0TFSI K04 Stage2 and Stage2+ vehicles
    Linear Throttle offers the driver more control over the vehicle than the factory standard throttle response. Rather than giving full load at low throttle input, Linear Throttle gives you exactly what you ask for. i.e. press the throttle down 25% and you get 25% of engine capability, press it down 100% and you get 100%. Giving a much more useable vehicle, a must have for the true driver.

    Fix to prevent sporadic ‘System too Rich at Idle’ fault
    Fix to issue previous seen on some ECU codes, not all 2.0TFSI K04 codes were affected.

    FAQ’s:

    Do I need to have this update?

    It’s not a requirement however it’s a FOC upgrade with benefits to the drivability of your vehicle. The best just got better!

    How much more power will my car have?
    The revised software is showing gains in the midrange with peak figures largely unaffected. As with all Revo software the emphasis is on the useable power, torque, smoothness and reliability. We aren’t tuning for ‘dyno/pub talk’ figures but for real world useable performance.

    Will my SPS still work with the new software?
    Your SPS will work with the same functionality it currently has. The performance modes will need to be altered to suit the new Revo settings once your car has been setup on the revised software.


    Please contact your Revo Dealer to arrange for your software update.
    Note: Revo Dealers reserve the right to charge a labour fee for their time.

    Over the next few days we will be arranging Revo 'update' events throughout the UK; details to follow.

    If you have any specific questions about these updates or the effect on your vehicle, please contact the Revo Support Office.
