We have specialized in tuning naturally aspirated (NA) or “all motor” 4.2L V8 engines since we started tuning the B6-S4 in 2008. Ever since then we have been the number one company when it comes to Audi V8 performance. Like our success with the B6-B7 S4, B7 RS4, and B8-RS5 4.2L has shown, our software has been proven time and time again to deliver real world performance. That continues with our tuning for the B8-S5 4.2L FSI V8.

Why is our tuning the BEST? Our Stage 2 performance ECU and TCU software is specifically designed to work in harmony together maximize the engine power output capabilities.  Following our success with the B7-RS4 and B8-RS5 4.2L FSI Performance Software.  Our tuning will give your S5 improved throttle response and more power throughout the entire RPM range leading to faster acceleration and a much more rewarding and refined driving dynamic.   

By making a ECU and TCU combination that works together we were able to do the following for your S5:

NOTE: The ranges are due to the fact that mods and ambient temp affect power so the increases are more when you have more power.

• 0-60 mph times decresed by 0.5 to 0.9 seconds
• Engine Rev limit increased to accommodate higher shift points
• 400 to 500 more RPM when stalling converter to get the hardest launch (power braking). Increases 60ft and 0-60 times.
• More aggressive throttle control in Sport Mode (Dynamic)
• Increased shifting speeds
• More assertive shifting in Sport mode
• 1-2 short shift issue in factory file fixed and raised 300rpm to 400rpm
• All other gears raised 300rpm to 400rpm
• Refined Drive and normal driving shifting

• Raised TQ limiters

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

You can download and view the instructions HERE to determine whether or not this is something you would like to do.
