Introducing JHM K04 ECU and TCU Tuning for the B8 A4 2.0T FSI! 

Our software will give your K04 B8-A4 2.0T FSI improved throttle response and more power throughout the entire RPM range leading to faster acceleration and a much more rewarding driving experience over A K03 car. Our experience in all motor or naturally aspirated FSI tuning has allowed us to safely maximize the capabilities of the 2.0T motor making it hit hard in the low end of the RPM range and then extract more power from it "up top" once the boost begins to taper off.

We have used our extensive experience and latest advancements in Audi ECU calibration to bring you the best high-performance ECU calibration for your 2.0T FSI. In our ECU tuning, we change 100s of parameters in the ECU to allow the 2.0T motor to make the most power it is capable of producing safely without sacrificing reliability and dependability. 

This is a one-and-done solution with only ONE Flashing Cable Required (JHM Power-Connect) and can be flashed in the convenience of your own home with an internet connection. 

By making an ECU and TCU combination that works together we were able to do the following:

• Engine Rev limit 
• More aggressive throttle control
• Increased shifting speeds
• More assertive shifting in Sport mode and after launching
• Launch Stall RPM raised 
• More aggressive and consistent Launch
• Refined Drive and normal driving shifting dynamics
• Decreased Transmission wear due to less slipping from faster shifting
• Raised TQ limiters
• More Agressive Torque Curve
• Maximum Boost for each gear with faster spool
• Safe EGT Management 
• Larger Range of Fuel Adaptation for More Power from Better Fuel
• Larger Range of Ignition Adaption 

FEATURING JHM LAUNCH ASSIST - Another advancement that we have brought to the B8-A4 2.0T Platform is our proprietary JHM Launch Assist. Developed for the B7-RS4 as an industry first, we have implemented our JHM Launch Assist on all 6-Speed Manual tunes for the B8-A4 2.0T. When activated and engaged, the JHM Launch Assist reliably gets your car from zero to all out acceleration every time!

OPTIONS: When you place your order for JHM Tuning, please specify your year, body type, octane, transmission type, and flashing method by using the drop down boxes below.

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
