FAQs – ECU Programming & Motorcycle tuning at PKB Performance

  1. What is ECU programming?
    The ECU (Engine Control Unit) controls all the important engine parameters – from injection and ignition to torque limiters. With ECU programming or an ECU flash, we customize these maps to your specific motorcycle.
    Goal: more power, better drivability, optimal throttle response – motorsport-proven and field-tested.

  1. How long does ECU programming take?
    A standard ECU tuning usually takes 1-2 hours.
    A custom dynamometer tune takes longer because the motorcycle is measured and adjusted multiple times. An appointment is absolutely necessary for this.

  1. Where is the ECU programming performed?
    All ECU programming and map optimizations are carried out directly in-house.
    We use our own performance test bench for professional tuning.
    Alternatively, you can send us your control unit by post – we will carry out the programming and send it back as soon as possible.

  1. Will I lose my warranty if I tune the ECU?
    Manufacturer warranties may be limited or voided by ECU tuning. We recommend checking this with your dealer or manufacturer beforehand. Many customers opt for tuning after the warranty period has expired.

  1. Is ECU tuning legal and compliant with German road traffic regulations (StVO)?
    ECU optimization is generally not approved for road use, as it alters the original homologation.
    Our ECU programming should therefore be understood as racing/export products.
    They can be used without restriction on the racetrack.

  1. What is a quickshifter (QS)?
    A quickshifter allows shifting without the clutch and without letting off the throttle.
    The result: lightning-fast gear changes, more stable handling and more driving fun – whether on the road or the racetrack.

  1. What is a fuel cut-off (fuel popping/fuel crackling)? Deceleration pops)?
    During overrun fuel cut-off, the injection is interrupted during overrun mode.
    This creates crisp popping sounds from the exhaust and can be combined with quickshifter systems to achieve even shorter shift times.

  1. What is a flame limiter?
    The Flame Limiter ensures spectacular flames from the exhaust at the rev limiter.
    Through precise control of injection & The ignition produces the typical racing sound – and the matching show to go with it!

  1. What does a regular ECU tuning entail?
    Adjustment of the injection maps
    Optimization of the ignition maps
    Adaptation to exhaust system & Fuel quality
    Removal of torque and speed limiters (model dependent)
    Activation of additional features such as quickshifter, launch control, overrun cutoff

    The result: noticeably more driving pleasure, healthy engine running, powerful performance & Increased torque.      

  1. Can I have my motorcycle restored to its original condition?
    Yes – we back up your original ECU software and can flash back to the factory settings at any time.

  1. How much does ECU programming cost?
    Prices vary depending on the model, control unit and desired scope.
    Standard programming starts from 50 €, Individual test bench tuning will be calculated separately.

  1. Do you also offer suspension modifications?
    Yes – besides ECU programming, we are also your partner for chassis optimizations and chassis modifications.
    We are an official service center for Öhlins & TracTive and authorized dealer for YSS Suspension.
    Whether it's service, modification, individual tuning or complete chassis tuning – we get the maximum out of your motorcycle.
    Our chassis work is carried out in-house and can be directly combined with ECU tuning or dyno work.

  1. Why can you do all that?
    Because we are not just a workshop, but a team of specialists with diverse backgrounds.
    We combine experience from motorsport, workshop practice, software and electronics development, as well as chassis and engine technology.
    We use this knowledge in a combined way.

  1. How many people are behind PKB?
    All together we are a team of 7 people!

  1. Are you also familiar with the topic of engine tuning?
    Of course! We tune and develop engine parts – from cylinder heads and camshafts to compression modifications, we are your contact.
