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/Cruze 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 customerservice@zzperformance.com. 

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.
