This product will connect inline with your fuel line and it will be constantly monitoring the fuels ethanol percentage and then sending a signal to the PCM. With our ZZP ATS/CTS PCM Tune setup for this kit, it will allow you to run any mix of e85/premium gasoline and the PCM will adjust the fueling, timing, and boost specifically for it.

This kit will not work without our PCM Tune that is setup for it.

Works on 2013-2015 ATS/CTS 2.0 liter LTG models. Will not fit the 2016 at this time due to a different ECU. If you have the twin turbo 3.6 liter ATS-V or CTS, you will need the ATS-V or CTS V Sport version instead.
