 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
