How it Works:
The FS2 uses an exclusive process of Dynamic Soft-Flashing not available anywhere else. Each FS2 comes programmed with a set of EPROM addresses that directly affect efficiency and performance. When the ECU attempts to read one of these addresses, the FS2 patches the factory value with one from its on-board performance tuned map.
The FS2 is based on our most powerful Dynamic Soft-Flasher, the VP12. Operating at 20MHz with plenty of Flash Memory, the FS2's 8-Bit CMOS microprocessor offers extended compatibility along with faster patching for safer, higher, and more consistent gains.
Will the FS2 void my warranty?
Unlike ECU ROM chip replacements or permanent ECU flashing, the FS2 makes no changes to the ROM itself and does not require opening the ECU. It will not void your factory warranty.
Will it be compatible with my current modifications?
Modifications that do not alter factory compression ratio or stroke are 100% compatible with the FS2. Many upgrades such as aftermarket intake and exhaust will compliment the FS2's performance. The device will automatically compensate for your modifications during its initial calibration.
What if I plan to add modifications later?
Anytime you add a modification that affects engine performance, you must reset the device and allow to recalibrate. During calibration the Volo Chip will extrapolate new target value sets based on your vehicle's current performance characteristics, fine tuning engine output.
How will the FS2 affect horsepower and torque?
The FS2 will cause no loss in power. For HP and torque gains, check out the VP12 on our website.
Will it work with HHO disabled?
Yes. HHO output is metered dynamically by formulation given intake air volume, fuel delivery, and O2 sensor output. The Volo Chip must be calibrated with the maximum HHO output you intend to use. The Chip can then adjust for any amount between zero up to your maximum on the fly.
Will I still need an EFIE or other device?
No. The FS2 was designed to replace EFIE, MAP sensor enhancers, and O2 sensor modifications. Using these in conjunction with the Volo Chip may cause erratic gains.
Why is it so much cheaper than other ECU mods?
The FS2 was purpose built and is not capable of more advanced features like altering rev limit or disabling the top speed governor.
How much can I expect to gain in my Fiat Stilo?
Gains with HHO disabled will average 15-18%. Gains with HHO enabled will vary greatly depending on many factors.
Installation time : 10-20 minutesTools required : Screwdriver, PliersThe FS2 does NOT include an OBD-II connector, but connects directly to the OBD-II port's data input/output via four tap-in connectors. Most OBD-II scantools will not interfere with operation.You must press the RESET button and allow the engine to idle 1-3 minutes to calibrate the device after first installation or after modifications. Frequent installation and removal of the device is not recommended.
