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-S5 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-RS5 4.2L FSI V8. We purchased our in-house B8-RS5 4.2L in mid-2017 and immediately began developing software. After countless revisions and putting the vehicle through our rigorous R&D process, we are happy to now offer the ultimate performance software for your B8-RS5 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-S5 4.2L FSI Performance Software, we began extensive research and testing with our in house B8-RS5 4.2L. Our tuning will give your RS5 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 RS5:
- Engine Rev limit increased to 8800rpm
- More aggressive throttle control in Sport Mode
- Increased shifting speeds
- More assertive shifting in Sport mode and after using Launch Control
- 1-2 short shift issue in factory file fixed and raised from 7800 rpm to ~8500 rpm
- All other gears raised from 8300/8400 rpm to 8500 rpm
- Launch Control RPM raised from 5500 to 6300
- Launch Control attempts raised from the 200 max limit to unlimited
- More aggressive and consistent Launch Control
- Refined Drive and normal driving shifting
- Current gear displayed on dash in all modes
- "True Manual Mode" Manual Mode holds and will not down shift or up shift (OPTIONAL)
- Higher pump speeds for transmission cooling.
- Higher clutch pressures at all RPM and LOADS
- Raised TQ limiters
Our preliminary testing we have shown exceptional results of 11.88@115mph on 91 Octane and in this video 11.89@116mph
In addition to optimal performance, our JHM Stage 2 Performance ECU and TCU Software significantly improves the RS5s EGT (Exhaust Gas Temperature). This is beneficial because lower EGTs will improve catalyst life, and better engine protection for long periods of hard use for Road Racing, Autocross, Etc..

and add to your cart after adding the tune, just selecting the option is NOT enough. Make sure you have THOROUGHLY read through the instructions and are confident that you can set your computer up correctly. If you select this option for your tune, you must select a shipping method for your order so we can ship you a JHM Tuning-Flashing Cable. Please select a shipping method once you've added the tuning and the flashing cable to your cart.

If you already have a JHM POWER CONNECT Cable, select "I already have a JHM POWER CONNECT Cable." **NOTE: This is a proprietary cable with drivers specific to our Flashing Software so you must make sure that you have a JHM POWER CONNECT Cable, NOT just a generic USB Vag Com cable.** After receiving your paid order, we will send you an authorization form which we will use to create your JHM Tuning Flash Browser account and login information.

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 two separate programs on your computer: VPN software to access our flashing server securely and our JHM Tuning Browser which is the program that writes the JHM Tune onto your car. 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.
