Description
If you already own an HP Tuners interface, buy our Starting Point Tune. After you flash your car and take some initial scans send us the file. We will make fine adjustments to the tune and return it for you to upload. Depending on the situation, this may require three to six iterations. Going forward, you will always have the ability to scan all ECM and TCM parameters.
Within the TCM we start by ensuring the latest GM software updates are applied, then adjust base line pressure tables for all forward gears, with TCC on and off, in addition to all base shift pressure tables. These changes will make your transmission shift more firm and crisp than stock, without feeling too harsh.
Within the CCM we adjust the active exhaust settings to make them more user friendly. For example, the exhaust baffles will no longer slam open under light throttle at 3,500 rpm.
To make sure we give you the best performance possible we ask customers to fill out our Tuning Questionnaire. (requires that you have a HP Tuners interface)
Tapout Tuning can tune the following control modules:
- ECM = engine control module (2016 through 2019 ATS-V engine settings)
- TCM = transmission control module (2016 through 2019 ATS-V A8 automatic transmission settings)
- CCM = chassis control module (2017 through 2019 ATS-V active exhaust settings)
The TCM (2) and CCM (3) tunes both require additional Universal Credits for the HP Tuners module. If you are ordering one of those options make sure you are adding the correct number of additional credits. Click here to add Universal Credits to your order.
