Note: This is an add-on that needs to be run with Unitronic software, not by itself. 

Unitronic is pleased to announce the official launch of UniFLEX, the most robust Flex Fuel package of Performance Software.

*Specific Tuned files are subject to availability for your ECU box code.  If Tuned Files are unavailable for your ECU box code, please submit a Tuned File Request or email [email protected] for more information.

Unitronic FLEX fuel-enabled ECU Performance Software Calibrations feature the implementation of its flex-fuel code and additional control mapping into the factory Bosch engine control modules. When combined with Unitronic’s UniFLEX hardware, Unitronic’s FLEX code receives ethanol content over the CAN-bus. It utilizes this fuel composition data to blend mapping of timing, boost pressure, fueling, and much more. Simplified, this allows for seamless transitions from 0% to 85% ethanol content — or said another way, 100% gasoline to 85% ethanol and anywhere in between, without needing an ECU reflash.

*After purchasing this add-on, Unitronic FLEX-enabled files will be available until the highest purchased ECU Software stage. If, for example, you upgrade from Stage 1 to Stage 3 on the ECU side, you will NOT need to repurchase the FLEX add-on to move up to one of the Stage 3 FLEX-enabled ECU calibrations.*

BOOST GAUGE RECALIBRATION

The OEM Boost Gauge has been recalibrated to show relative/gauge pressure rather than absolute pressure.

COOLANT TEMPERATURE PATCH

The coolant temperature gauge has been patched to show actual coolant temperature as opposed to the "dummy" gauge as is factory.

INCREASED POPS AND BANGS

Due to popular demand, Unitronic has implemented sportier impulse combustion sound tuning.

HIGH SPEED DATA LOGGING

High-Speed Datalogging with proprietary custom ECU code patch that allows for data acquisition of hundreds of variables collected at 50Hz in a single log, which allows to collection and analysis of 100% of the OEM process. Other logging tools severely limit data collection variables which make it impossible to have a complete view of the OEM processes, therefore limiting the other tuner's abilities.

EXPANDED UNILOGGER SUPPORT

Additional UniLogger support with custom tailored ECU logging profiles for each SIMOS 19.6 EPK to collect all the data required at the highest sampling rate possible for fast and efficient data collection.

OEM BIO-FUEL OBD2 PID

Thanks to Unitronic's proprietary code-based adjustments incorporated into its UniFLEX Enabled ECU software, fuel composition data (ethanol content and fuel temperature) is streamed via the OEM bio-fuel OBD2 PIDs, allowing 3rd party devices like P3 gauges to pickup and display ethanol content via the OBD2 port.

Ethanol Monitoring Within Your Digital Dash

When a vehicle is flashed with a Unitronic FLEX enabled ECU calibration and cruise control is set to the OFF position, the factory power gauge will now show ethanol content percentage. Best of all, cruise control functionality remains unaffected and the power gauge works like stock, showing engine power when the cruise control is turned on and/or engaged.

Unitronic E85 Manager iOS/Android Application

Unitronic's E85 Manager application offers another way for you to wirelessly monitor ethanol content, calculate future gas/ethanol content blends depending on your performance goals and more while using your mobile device's Bluetooth connection. Compatible with iOS and Android devices.

Unitronic's E85 Manager allows you to wirelessly view your vehicle’s current ethanol content and integrate this fuel composition data over your vehicle's CAN-BUS, when combined together with the UniFLEX module, an Ethanol Content Sensor and ECU Performance Software calibrated to add Flex Fuel functionality, while using your mobile device's Bluetooth connection.

The included E85 Mix Calculator allows you to calculate current and future gas/ethanol content blends to ensure you can achieve your target ethanol content using your fuel tank size, current fuel level, current ethanol content, target ethanol content, and more!

• View Ethanol Content & Fuel Temperature

• Customize Sensor Calibration Offsets and CAN integrations**

• E85 Mix Calculator

• OTA Updates

**Even if you’re not using UniFLEX with Unitronic’s Flex-enabled ECU Performance Software calibrations, customizable CAN integrations are available for use with other tuner’s ECU calibrations, negating the need to run additional wires to the ECU, through the firewall into the passenger compartment, or the need to keep additional accessories connected to the vehicle’s OBD2 port. We encourage you and your tuner to reach out to learn more about the customizable CAN integrations available with UniFLEX!
