JH Motorsports is proud to release our JHM C7 S6-S7 and D4-A8 4.0T - RS7 or RS7-R Turbo  ECU and TCU Software!

 *NOTE: THIS SOFTWARE IS A FREE UPGRADE IF YOU ALREADY OWN JHM STAGE 1 OR 2 ECU/TCU COMBO *

Experience the ultimate in performance with our Stage 3 RS and RS+ performance ECU and TCU software designed to maximize the engine power output of your vehicle equipped with RS7 or RS7-R turbos. Developed and refined by our engineering team over years of daily driving and abuse, our software takes the guesswork out of tuning and provides the most comprehensive and effective solution available.

With our one-and-done solution, all you need is one flashing cable and an internet connection to flash your ECU and TCU with our optimized software. Our transmission tune is specially optimized with a launch control that eliminates massive tire spin and provides consistent launches on street tires and RS7 turbos. You can easily adjust the launch RPM based on your tires, traction, and driving conditions, all backed by our extensive testing and hundreds of test passes performed.

By making an ECU and TCU combination that works together, we were able to deliver unmatched performance for your C7 S6-S7 and D4-A8 4.0T. Our software features an increased engine rev limit of up to 7200 RPM, more aggressive throttle control, increased shifting speeds, and faster clutch clamping with higher clamp loads. You'll also enjoy more assertive shifting in Sport mode and after launching, as well as a variable launch RPM that delivers a more aggressive and consistent launch.

Our software is also designed to refine drive and normal driving shifting dynamics, decrease transmission wear by reducing slipping from faster shifting, raise TQ limiters, and provide a more aggressive torque curve. Plus, you'll enjoy maximum boost for each gear with faster spool, safe EGT management for stock catalyst protection, and a larger range of fuel and ignition adaptation for more power from better fuel. Finally, our ESP/traction control is adjusted to eliminate micro braking due to tire spin, helping to prevent axle breakage when launching.

Upgrade to Stage 3 enjoy the ultimate in power and performance with our Stage 3 RS and RS+ performance ECU and TCU software. Get yours today and experience the difference for yourself!

FLASHING INFORMATION:

For Flashing Method, select "Flash Myself, SEPARATE POWER CONNECT Cable Purchase Required, CLICK LINK BELOW" if you're going to be buying a cable from us and flashing your car on your own. You'll need to add this option.

GO HERE FOR JHM POWER CONNECT CABLE

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. Instructions for installing the flashing software on your computer will be emailed to you after purchase.

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. This is the information you will use to access our server and flash your car with the JHM Tuning-Flashing Cable that you already have.

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.
