Our team partnered and worked with HP Tuners engineers to validate the flashing procedure, beta test this new product and define all the required calibration tables. Full tuning support is now available, and allows proper ECM calibration for aftermarket intake, throttle body, downpipes and more. Enjoy increased boost and higher rev limiters with no more Check Engine light!
Please note that you must ship your original ECM to HP Tuners for unlocking service in order to start the tuning process. This means you will need to plan ahead to be without your car for a short period of time. Although it’s technically possible to learn a new ECM to your car, that process would permanently immobilize your original ECM, and there would be no way to restore it’s functionality. For this reason, it will be necessary to ship your original ECM to HP Tuners for unlocking service.
All Global B cars will need to have their ECMs unlocked in order to be tuned. If your car has the A10 Automatic transmission, you also have the option to get your TCM unlocked and tuned, but this is not required.

The ECM is actually the easiest part to remove from the entire car. Coincidence? We don’t think so. The ECM is located under the hood on the passenger side fender. For cars with A10 transmission, the TCM is just behind/under the ECM.
To make sure we give you the best performance possible we ask customers to fill out our Tuning Questionnaire.
When you purchase a Tapout tune, we typically cover any edits you may want or need for the first 30 days. After that, our annual or monthly tuning subscriptions allow you to continue with data scan review and tuning edits. This would cover things like new periodic checkups, new mods, different octane fuels, race track specific tunes, etc. The Prepaid One Year Subscription provides access to tuning services (at a 50% discount compared to ordering a Basic Monthly Subscription)!
