We've been providing industry leading Audi Transmission Software since 2009! 

Unleash the true power of your ZF 8-Speed Transmission with JH Motorsports TCU software - the ultimate performance upgrade for your car! Our software is specifically designed to be flashed directly to your transmission control module through the OBDII port with JH Motorsports proprietary AL551 calibrations and our JHM Power-Connect Flashing Suite, unlocking its full potential and transforming your driving experience.

Our team of experts has spent countless hours researching and testing our in-house ZF8 Test Mules to create the ultimate software for your car. Enjoy faster acceleration, increased shifting speeds, and more assertive shifting in Sport mode and after launching. With increased shift points over 1000 RPM above factory (Proper ECU Software Required), you'll experience an exhilarating rush every time you hit the gas.

But that's not all - we've also raised the launch stall RPM from ~2000 to ~3000, delivering a more aggressive and consistent launch every time. Our refined Drive and normal driving shifting dynamics ensure a smooth ride, while decreased transmission wear due to less slipping from faster shifting guarantees you can push your car to the limit with confidence.

Our raised torque limiters with improved torque management provide the perfect balance of power and control, ensuring you never have to sacrifice one for the other. Upgrade to JH Motorsports TCU software today and experience a driving experience like no other!

Alternatively, you can take advantage of our switch discount to get our matching JHM ECU software for your vehicle, unlocking its full potential.

DISCLAIMER: JHM is now using proven flashing technology in order to get our tunes on our customers' cars in the quickest and most convenient way possible. You will be installing a proprietary JHM software that works ONLY with our flash cable (supplemental software such as Microsoft .net may be required). This program is what allows you to detect your ECU part number, fill in your information, select the correct program based on your hardware and then write JHM Tune to your ECU all through your OBD II port. Both of these programs are highly specific when it comes to configuring your computer to run them properly. While every effort has been made to clearly and completely explain this configuration in our instructions, the customer will ultimately be responsible for removing or disabling their own or third party anti-virus software or firewalls that will block the port required for you to log into our flashing server (see the link to our instructions below to determine whether or not this is something you'll be able to do). Basic technical support provided by JHM to help install these programs on your computer, diagnose programs with your computer, and/or internet connection may be subject to an hourly fee. Additionally, if something happens to your ECU during the flashing process, you should be able to restore it using our software. If you are still unable to make the ECU flash properly, you will be responsible for all costs associated with restoring your ECU and fixing the issue.

Requirements for Tune: 
- Windows computer with at least 1 USB (Universal Serial Bus) port 
- Wired Broadband Internet Connection (wireless can be unreliable) 
- JHM Tuning-Flashing Cable (Flash cable length cannot extend beyond 10 ft long unless a powered USB hub is installed in-line. 
- Battery Charger or equivalent power source capable of sustaining a 40 amp charge
