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 Sonic 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. 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. Larger injectors are required due to increased fuel system demand, but sizing will depend on what turbo setup you are running etc. If you need assistance choosing the correct injector size reach out to 

This kit will not work without our PCM Tune that is setup for it. This kit and instructions are built for the Chevy Sonic. Does not work on the Cruze, we are working on that kit currently.

Super easy install

This works and it was a super easy install the only difference is when your connecting into the j port on the ecu I wish the directions would have an arrow or a circle on the specific pin section on the connection you have to put the wire in other then that it’s easy and took me maybe 15 minutes to set up with the proper tools. It took longer to pre read the directions then it was to install. I don’t have the zzp tune but it was compatible with another tune that I already had.
