JHM Software Tuning for B7-A4 2.0T, K04 Upgrade (K04 turbo, S3 injectors and HPFP required) | JHM-B7A420TTUK04

Introducing JHM Tuning for the C5-allroad with the 40v 4.2l V8!!! 

If you are looking for the ultimate in tuning for your C5-allroad whether it is an Automatic or Manual transmission, 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.

The minimum required for your exhaust system is as follows:
-Downpipes: Piggie downpipes (which we sell) are good. Aftermarket downpipes like the Fast Intentions 2.5 inch downpipes we sell are better. Our JHM Longtube Headers are the best setup. However, you will need to do some minor modifications to run our Fast Intentions Downpipes or our JHM Headers on your C5-allroad.
-Cat-back: You must have a high-flow, dual 2.5 inch cat-back with an X-pipe. The Magnaflow cat-back we offer for the C5-A6 2.7T is the most convenient solution for a C5-allroad 4.2L. With slight modifications it will bolt right up to your allroad.

 In typical JHM style here are some videos of the performance our tune is capable of producing on the B6-B7 S4 Platform with a very similar engine:

  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
