How Do The Volo FS3 Fuel Economy Chips Work

Similar to the other performance and fuel economy chips we carry, the FS3 Chip is a special process called "Dynamic Soft-Flashing."

Working with your vehicle's ECU the FS3 will evaluate the intake air temperature and volume, the oxygen levels in your exhaust, engine speed and load, and a lot of other variables to establish the best efficiency in the fuel delivery rate and timing at up to 256 separate load points.

The FS3 Volo Chip replaces timing and fuel delivery values stored in the ECU's short term memory with optimized values.

This produces the same results as other pricey ECU upgrades, at a fraction of the cost. The FS3 DOES NOT alter rev and speed limiters. Increase MPG 10% to 18% with this fuel economy chip, without loosing horsepower and torque.

Install It In 15 Minutes

The FS3 installs easily into your high speed serial input/output to communicate directly with the ECU through the OBD-II port.. Installation video and vehicle specific wiring print-outs are available on our
best performance chips Instructions page. Fuel Economy Chips

No fine-tuning or vehicle comprehension needed. All gas saving chips come pre-programmed with maps for your specific vehicle. Simply install and hit the reset button for automatic calibration, "set it and forget it".

The FS3 does NOT come with an OBD-II connector. It connects directly to the OBD-II port's data lines. It will not interfere with sacn tools and gauges for OBD II.

Where is my ODBD II port? The connector has to be three feet of the driver and must not require any tools to be exposed. Don't forget to check under the dash and behind ashtrays. Usually you can find it right under your steering column.

Not Sure If You Have An OBD II?

There are two ways to absolutely know if your vehicle is OBD II 1) if there is a connector as shown above and 2) a sticker or plate under your hood that reads "OBD II Compliant"

All light trucks and cars built and sold in the U.S. after January 1, 1996 were mandated to be OBD II equipped. So, even if the vehicle was built in late 1995, all 1996 model year cars and light trucks are compliant.
