JHM ECU Tuning or Tune for D3 S8 5.2L V10 FSI

Introducing JHM Tuning for the D3 -S8 5.2L V10!!! 

IMPORTANT: After purchase you must email sales@jhmotorsports.com with your order number to receive your account credentials.

If you are looking for the ultimate in tuning for your D3 -S8 5.2L V10, you are in the right place.

 Why is our tuning the BEST? Our tuning is specifically designed for an aftermarket exhaust. It is not another “cookie cutter” software that will work on a stock car, thus limiting its abilities. 

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

UPDATE 4-1-21: All C6 S6 V10s and D3 S8 V10s use ONLY the one POWER CONNECT cable to flash BOTH ECU and TCU. So if you have one of these cars do NOT buy the OLDER TUNING flash cable. This is the ONE and ONLY cable you ned to do BOTH ECU and TCU..

For Flashing Method, select “Flash Myself, SEPARATE 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 POWER CONNECT 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 manufactured for us 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 POWER CONNECT 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 POWER CONNECT 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.

If you’d like to get tuned at a JHM dealer close to your location, you can find one using our Dealer Map by clicking the “Dealers” Tab at the top of this page. You will need to contact your preferred dealer directly and schedule a tuning appointment with them. You shouldn’t be charged more than an hours’ worth of labor for your JHM Flash.

DO NOT SHIP YOUR ECUs TO JHM without contacting us first!!!

NOTE for customers with an ECU that already has brand-x software:

**UPDATE, 10-1-2012**: JHM Flash Tuning technology will overwrite **most** previous tuning on your ECUs. If you’re already tuned with a poorly performing, “brand-x” ECU tune you do not need to worry about it interfering with the process for becoming JHM Tuned.
