FAQ GUBELOG ( series 01-02-03) – MULTIFUNCTION DATA LOGGER

What is the GUBELOG series and what is it designed for?

GUBELOG is a range of compact, high-performance multifunction dataloggers built for precision acquisition in motorsport, automotive, industrial machinery monitoring, precision agriculture, process analysis and R&D laboratories. The system acquires, synchronises and records up to 38 inputs simultaneously.

  • GUBELOG-01 — 1 Hz GPS/GNSS receiver with internal antenna, prepared for connection to an external Wi-Fi module for data transmission and cloud monitoring.
  • GUBELOG-02 — 1 Hz GPS/GNSS receiver with internal antenna, plus an integrated LTE module with SIM card that sends telemetry straight to the cloud over the cellular network.
  • GUBELOG-03 — designed specifically for high-dynamics motorsport: a high-frequency 10 Hz GPS/GNSS receiver with external antenna for millimetre-accurate trajectory tracking.

The housing is made of PA12 nylon with very high mechanical resistance. The unit is rated IPX7 — protected against dust, splashes, oils and temporary immersion — and operates reliably between −20 °C and +85 °C.

Which inertial and navigation sensors are built into the hardware?

  • GPS/GNSS receiver — 1 Hz on the 01 and 02, 10 Hz on the 03, for coordinates and lap time calculation.
  • 6-axis inertial platform (IMU) — three accelerometers (±30 g) and three gyroscopes (±2000 °/sec), sampled internally at 1125 Hz with hardware low-pass filters.

What sampling rates can be set for the external channels?

Rates range from 0.001 Hz for slow monitoring up to peaks of 200 Hz or 400 Hz for fast telemetry acquisition.

How many analogue and digital inputs are available, and of what kind?

  • 8 analogue inputs (12-bit ADC) — four 0–5 V voltage channels and four 0–20 mA / 4–20 mA current channels, with a built-in 250 ohm pull-down resistor.
  • 4 digital frequency inputs — for pulse signals from 0.1 Hz up to 20 kHz, such as RPM and wheel speed.

How do the two digital outputs (DO1 and DO2) work?

They are tied to software alarms and generate a 0–5 V signal, or drive external relays as a low-side switch rated at a maximum of 60 V and 1.5 A, so that automated actions can be triggered from the telemetry.

Which main connector does the unit use?

A 26-pin automotive-grade JAE Electronics MX23A26NF1 connector, sealed to IPX7, with a Click-Lock mechanical latch that holds against vibration.

Which CAN bus protocols can GUBELOG handle?

The unit has a High-Speed CAN 2.0B bus with up to 16 channels. It supports OBD-II, SAE J1939, ISOBUS (ISO 11783), OpenCAN (EN 50325-4) and custom protocols. A CAN Bridge function is included, which retransmits onto the bus the physical values acquired from the analogue and digital sensors.

Where is the data recorded, and how is it downloaded?

Data is written in RAW format to an internal microSD card; 16, 32, 64 and 128 GB cards are supported. Download is over USB-C through DataStudio, or by removing the microSD card and reading it directly on a PC for a much faster transfer.

What is AI Analyst in the DataStudio software?

AI Analyst is a multi-agent artificial intelligence system built into GUBELLINI DataStudio. It analyses datasets, runs Fourier transforms (FFT), searches for anomalies and produces professional technical reports in PDF.

FAQ GUBENAV – 6-AXIS IMU AND HIGH-DYNAMICS 100 HZ GPS/GNSS SENSOR WITH CAN 2.0B

What is GUBENAV, and why is it more than a racing GPS antenna?

GUBENAV is not a simple receiver but an advanced positioning and dynamics module, combining a GPS/GNSS receiver with a 6-axis ICM-20649 inertial platform (IMU). Through sensor fusion algorithms it calculates coordinates, speed, heading and the true attitude of the vehicle, merging the data at a 100 Hz update rate.

In which sectors and on which vehicles is GUBENAV used?

It is used in motorsport, for trajectory and lean and pitch angle analysis; in precision agriculture, for ISOBUS and NMEA2000 autonomous guidance systems; in marine applications; on automated guided vehicles (AGV); and on R&D test benches.

What are the technical characteristics of the internal sensors?

It carries accelerometers (±30 g) and gyroscopes (±2000 °/sec) sampled internally at 1125 Hz, with hardware low-pass filters. The processor runs the sensor fusion algorithm at 200 Hz.

Which quantities does it compute, and how often does it transmit them?

It provides latitude, longitude, speed, heading (yaw), linear accelerations on X, Y and Z, and angular rates for pitch, roll and yaw. The update rate of the packets on the CAN bus can be set to 1 Hz, 10 Hz, 50 Hz or 100 Hz.

What are the dimensions and power requirements?

Power is 9 V to 24 V DC with a draw of just 150 mA. The PA12 nylon body measures 93 × 63 × 30 mm, weighs 180 g and is sealed to IPX7.

Which CAN bus protocols does GUBENAV support?

Two standards, configurable over USB through DataStudio:

  • GUBENAV proprietary protocol — built on four customisable 11-bit or 29-bit CAN IDs, suited to pairing with the GUBELOG-03 and to motorsport use.
  • NMEA2000 standard protocol — transmits PGN 129025 (position) and PGN 129026 (course and speed over ground, COG/SOG) on extended 29-bit IDs.

Is GUBENAV compatible with third-party dataloggers and control units?

Yes. A standard CAN database file is supplied (gubenav.dbc) containing all definitions, scaling factors and offsets, so the unit can be integrated immediately into any data acquisition system.

How should GUBENAV be positioned and oriented?

The sensor must be mounted perfectly square to the vehicle axes: the X+ axis pointing in the forward direction of travel and the Y+ axis pointing upwards, towards the sky. It needs a clear view of the sky, away from metal panels and sources of electromagnetic interference.

How is GUBENAV installed on vehicles subject to heavy vibration?

It must be anchored rigidly to a structure that does not flex, and never mounted on soft plastics. Where vibration is extreme — single-cylinder engines or agricultural machinery — rubber anti-vibration mounts are recommended, to prevent the accelerometer data from saturating.

Is data recorded by the MICROLOGGER compatible with the analysis software?

Yes. Datasets recorded by the MICROLOGGER are natively and fully compatible with the GUBELLINI DataStudio suite. The acquired files benefit from exactly the same analysis functions available for GUBELOG, including advanced statistics, mathematical Virtual Channels and the AI Analyst artificial intelligence integration.

FAQ MICROLOGGER – ULTRA-COMPACT CAN BUS DATA LOGGER

What is the GRIPONE MICROLOGGER, and how does it differ from the GUBELOG series?

The GRIPONE MICROLOGGER is an ultra-compact datalogger designed to acquire data exclusively over a CAN bus network. Unlike the GUBELOG series, the MICROLOGGER has no analogue inputs, no digital inputs, no inertial sensors (IMU), no GPS module and no Wi-Fi or LTE connectivity. It is the right choice when the job is simply to record the traffic of an existing CAN network in a very small space.

What are the dimensions and electrical characteristics of the MICROLOGGER?

The MICROLOGGER is exactly half the size and weight of a standard GUBELOG unit, which makes it suitable for installations in tight spaces or on compact wiring. Its electrical characteristics are identical to those of the larger series: it runs on 7 V to 24 V DC, with the same low power draw and the same reliability.

Which CAN bus protocols can it read and record?

The device shares the CAN bus specifications of the GUBELOG family. It interfaces with High-Speed CAN 2.0B networks and supports, through software configuration, OBD-II, SAE J1939, ISOBUS (ISO 11783), OpenCAN (EN 50325-4) and custom architectures.

How is the MICROLOGGER programmed, and how are datasets downloaded?

Programming and initial configuration are done over USB with the free GUBELLINI DataStudio suite, exactly as for the GUBELOG series. Recordings are saved to an internal SD card. Downloading, however, is by SD card only: the memory card has to be removed from the device and read directly on a PC. Direct telemetry download over USB is not supported on this model.

Is data recorded by the MICROLOGGER compatible with the analysis software?

Yes. Datasets recorded by the MICROLOGGER are natively and fully compatible with the GUBELLINI DataStudio suite. The acquired files benefit from exactly the same analysis functions available for GUBELOG, including advanced statistics, mathematical Virtual Channels and the AI Analyst artificial intelligence integration.

FAQ GRIPONE ISIDE 2 – TRACTION CONTROL SYSTEM

GRIPONE ISIDE 2 is an additional ECU that work as traction control to manage the power of engine and limit the sliding of rear tyre… It is a extremely fast traction control but also a reliable anti wheelie control

No, GRIPONE ISIDE 2 works as traction control but also as wheelie control  and gear quick shifter.

GRIPONE ISIDE 2 is available in plug & play kit. Every kit includes: one ECU, one wiring loom, +/- remote buttons (to change the level of control), one remote led (to advise the rider when GRIPONE is operating on the power),  one USB cable (to programm the ECU), the software to manage the maps (XP, VISTA, WIN7, WIN8, WIN10, WIN11). Speed sensors, brackets kit for the speed sensors (not plug & play) and quick shifter additional kit are avaiable as optional upon request.

 TRACTION CONTROL:

When we say that GRIPONE ISIDE 2 can work with or without speed sensors on the wheels, it means that GRIPONE ISIDE 2 base kit does not include the speed sensor . At this stage, the traction control works using a sophisticated algorythm that evaluate the tyre load, the lean angle (by the internal inertial platform) and the RPM rate of change. When these three parameters do not match the correct range, GRIPONE reduce the power to avoid the sliding of rear tyre.

As soon you plug the optional speed sensors kit, GRIPONE ISIDE 2 is able to detect the wheel speeds and automatically it start to function using a second set of strategies to control the rear sliding. At this stage GRIPONE is more powerfull and more accurate then any other system, because it combine both strategies appling the propper power reduction.

WHEELIE CONTROL:

As well, the anti wheelie control use two different set of strategy. Without speed sensors, GRIPONE ISIDE 2 evaluates the pitch angle and the pitch rate by the inertial platform. As soon the pitch angle is bigger then a certain value, GRIPONE reduce the power.

When you include the speed sensors in your GRIPONE system, the anti wheelie apply the  second strategy estimating the front and rear speed and their accelerations. One more time at this stage GRIPONE combine both strategies to evaluate the propper power reduction.

QUICK SHIFTER:

With optional gear shift sensor kit GRIPONE ISDE works as proffesional quick shifter. One device for many functionalities

GRIPONE  can be connected up to 4 cylinders (via 4 coils or 4 injectors). The connection varies from bike to bike (refer to the list of applications to verify the type of connection for your bike). GRIPone takes power directly from the coils or from the injectors so it does not need to bring any wires to 12volt. In most of our applications, GRIPONE is connected to one coil and by an additional wire to the ground of the bike (or to the negative pole of the battery).

Unplug the battery

Access the battery and disconnect the two poles + and -. When you work on electricity it is better avoid short cut.

Remove the tank

GRIPONE must be connected to the coils so remove the fuel tank and the air box to access to the engine’s head and the coils

Plug the wiring loom

Unplug one coil (normally the second or third cylinder)  from the main harness and use the plug&play harness to bridge it

Place the wiring loom

Extend the wiring to the point where you want to place the GRIPONE control unit. Normally the most suitable place is under the saddle or in front of the motorcycle

Connect the groud

The wiring loom includes one wire with a end that must be connected to the ground. Remove a 6mm screw from the chassis and plug the wire in that point. Tight again the screw.

Place the ECU

The ECU must be placed in the front end of the motorcycle. Try to find a position where it is not too close to heat sources. Fix the ECU on a foam (or rubber) support and bring the wire to the plug&play wiring loom and connect it.

Place the remote led

The remote led help you to keep an eye on what is going on with your GRIPONE. For example t blink when your are sliding on wheely. close to the dashboard so you can see it anytime.

Fix the buttons

You can fix the buttons on the left handle bar by the included bracket. while riding, you can change level of control by the asphalt condition.

No. GRIPONE wiring loom is a plug & play loom that can be plugged to the OEM loom with original connectors.
The speed sensors must be placed in proximity of the brake disk (front and rear) in such a way as to detect the passage of the screws that secure the brake disk to the wheel rim. as accessory, we can provided a set of universal brackets that fits generally to a wide range of models. If the brackets are not compatible with the bike, it is up to the customer to adapt them or create new ones.
When GRIPONE should decrease the power, it cuts a certain number of firing (or injected if it is connected to the injectors) at a certain frequency. The number of cuts and the frequency are preciselly defined by an algorithm, based on lean angle, RPM and tyre load. The firing cut prevent damages to the engine because it keep the temperature of engine low. In addition the cut is earable so the rider can manage the throttle easly.
GRIPONE can be adjusted in two ways. First of all by sending a map from the computer to the unit (via USB cable). On our website there is a free software that allows you to open/edit/save/send the map. The map contains many parameters. Each parameter varies one function of the traction control, wheelie control and quick shifter. By sending the map to the unit you can fix the operation of GRIPONE.
Moreover you have 2 buttons by which you can move (up and down) the level of traction control and the level of wheelie control. Based on the parameters included into the sent map, the button lets you change the operation on GRIPONE.
During the first installation the user can connect to our online database to the site www.gripone.com to get the “base map”. Each engine (4, 3 or 2 cylinders) has its own base map. The map must be open with software and sent to the unit via USB. It is recommended to initially use the base map. After a few tests you can change the parameters in the map to adjust the GRIPONE operation according to your needs.
GRIPONE S3 has two buttons on the handlebars, included in the kit (one green and one red). These buttons are used to vary the sensitivity of the traction control, on 3 levels: MAP TC1, TC2 MAP and MAP TC3. Besides changing the sensitivity of the traction control, the buttons can enable / disable all controls and turn on / off the pit limiter.
The inertial platform IMU is a sensor that detects accelerations along the three axes of motion (longitudinal, lateral and vertical). Accelerations provide basic data for the elaboration vehicle’s dynamic motion. Through the inertial platform, for example, GRIPONE is able to establish the wheel loads and the leaning angle of the motorcycle. THE Inertial platform is internal to the ECU so you do not need to install other external devices.
