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-V or CTS V Sport tune ($499, in person, or sent in ECM) 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. Running ethanol will increase the need for a larger fuel system, we highly recommend monitoring your fuel pressure to make sure it is holding at the correct PSI during WOT. 

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

Works on 2016-2019 LF4 ATS-V and 14-17 LF3 CTS V Sport models only. If you have a 2.0 liter engine, you want this one instead.
