What Does the HP Tuners MPVI3 Do?

The HP Tuners MPVI3 enables communication between the vehicle’s OBD-II port and the VCM Suite software running on a computer.

Depending on vehicle and control module support, the following operations can be performed with the MPVI3:

• Reading the engine control module software

• Reading the transmission control module software

• Saving the original vehicle software to a computer

• Viewing tuning tables and parameters

• Performing engine and transmission tuning operations

• Writing the modified software back to the control module

• Reading and clearing diagnostic trouble codes

• Reviewing records related to the Malfunction Indicator Lamp

• Viewing live sensor values

• Analyzing vehicle operating data in graphical form

• Recording datalogs during road and dyno tests

• Performing standalone data logging without a computer connection

• Running supported vehicle-specific service functions

The features available with the MPVI3 may vary depending on the vehicle’s make, model, production year, engine, transmission, and installed control modules.

Reading Vehicle Software

HP Tuners VCM Editor enables the software stored in supported engine and transmission control modules to be read.

The original vehicle software can be saved to the computer in HP Tuners’ HPT file format. This allows the original software to be backed up before starting the tuning process.

Keeping the original file makes it easier to:

• Compare the changes made

• Return to the previous software when necessary

• Organize and archive different tuning files

• Track vehicle and software versions

Tuning Operations with VCM Editor

VCM Editor is the HP Tuners software used to view and modify tuning parameters within the engine and transmission software of supported vehicles.

Depending on vehicle and control module support, the main adjustable areas may include:

• Fuel tables

• Ignition timing tables

• Torque management parameters

• Engine RPM limits

• Vehicle speed limits

• Throttle control parameters

• Electronic fan activation and deactivation temperatures

• Turbo boost control values

• Target lambda values

• Target air-fuel ratios

• Engine torque limits

• Transmission torque limits

• Gear shift points

• Transmission line pressure values

• Torque converter lock-up settings

• Tire diameter settings

• Final drive ratio settings

• Speedometer corrections

Writing the Modified Software to the Vehicle

Once the tuning process has been completed in VCM Editor, the modified software can be written back to the vehicle’s supported control module through the MPVI3.

During this process:

• The original vehicle software should be backed up.

• The vehicle battery voltage should be kept stable.

• A professional battery support unit should be used when necessary.

• The computer’s sleep mode should be disabled.

• The correct vehicle software should be selected.

• The OBD-II and USB connections should be checked.

• The ignition position should be set according to the instructions.

• Connections should not be interrupted before the writing process is completed.

Diagnostic Operations with VCM Scanner

The HP Tuners MPVI3 can be used not only for tuning but also for performing diagnostic checks on the vehicle.

Using VCM Scanner:

• Diagnostic trouble codes can be read.

• Applicable trouble codes can be cleared.

• Records related to the Malfunction Indicator Lamp can be reviewed.

• Emission system data can be displayed.

• Live sensor values can be monitored.

• Vehicle operating parameters can be recorded.

• Freeze-frame data can be reviewed.

• Supported special functions can be performed.

• Learned engine and transmission values can be reset on certain vehicles.

• Tire and final drive ratio settings can be adjusted on supported vehicles.

Live Data Monitoring and Datalogging

VCM Scanner enables live vehicle data to be displayed and recorded in real time.

Depending on vehicle support, the main values that can be monitored include:

• Engine speed

• Vehicle speed

• Throttle position

• Engine load

• Ignition timing

• Short-term fuel trim

• Long-term fuel trim

• Lambda value

• Air-fuel ratio

• Oxygen sensor values

• Manifold absolute pressure

• Turbo boost pressure

• Fuel pressure

• Engine coolant temperature

• Intake air temperature

• Gear information

• Transmission fluid temperature

• Engine torque values

• Torque management data

• Knock retard values

Live data can be displayed in table, graph, or gauge format. Recorded datalog files can be used to analyze the effects of tuning changes on the vehicle.

This allows the results of fuel, ignition, turbo boost, torque management, and transmission settings to be evaluated more accurately under different operating conditions.

Standalone Data Logging

The HP Tuners MPVI3 can record vehicle data to its internal memory without remaining connected to a computer, thanks to its Standalone Data Logging feature.

Standalone data logging can be particularly useful for:

• Road tests

• Dyno tests

• Full-load tests

• Acceleration tests

• Long-duration driving records

• Turbo boost monitoring

• Fuel system analysis

• Engine temperature monitoring

• Tuning validation

• Racing and track applications

Data logging can be controlled using the button on the device or through predefined start and stop conditions.

After the test is completed, the MPVI3 can be connected to a computer, and the recordings can be viewed and analyzed through VCM Scanner. Standalone Data Logging and advanced recording functions are included in the MPVI3 Pro Feature Set.

Pro Feature Set

The Pro Feature Set is the professional feature package included as standard with the HP Tuners MPVI3.

The package includes:

• Standalone data logging without a computer

• Advanced datalogging features

• PROLINK+ connection support

• Data acquisition from external sensors

• Viewing and recording analog and CAN data through VCM Scanner

Using the PROLINK+ cable, data received from compatible external sensors can be recorded in the same datalog file as live data obtained through the vehicle’s OBD-II connection and analyzed together.

The PROLINK+ cable is sold separately.

PROLINK+ Support

PROLINK+ is an optional connection cable that transfers measurement data from external sensors to the MPVI3 and VCM Scanner system.

PROLINK+ can simultaneously record:

• Two 0–5 V analog sensor signals

• One CAN bus signal

This connection can be used in professional tuning applications involving:

• Wideband lambda sensors

• External MAP sensors

• Turbo boost pressure sensors

• Fuel pressure sensors

• External temperature sensors

• Compatible CAN-based measurement devices

Universal Credits Licensing System

HP Tuners uses a credit-based licensing system called Universal Credits for tuning operations.

The software of a supported vehicle can be read and saved to a computer. However, the relevant vehicle or control module may need to be licensed using Universal Credits before the modified software can be written back to the vehicle.

The number of credits required may vary according to:

• Vehicle make

• Vehicle model

• Production year

• Engine option

• Transmission type

• Control module type

• Number of control modules to be licensed

Vehicle Compatibility

The HP Tuners MPVI3 can only be used for software reading, tuning, and writing operations on vehicles supported by HP Tuners.

The following information should be considered when checking compatibility:

• Vehicle make

• Vehicle model

• Production year

• Engine displacement

• Engine code

• Transmission type

• Engine control module type

• Transmission control module type

• Required number of Universal Credits

• Required cables or adapters

• Required unlock procedures

• Control module service requirements

The presence of a vehicle manufacturer on the HP Tuners supported vehicle list does not mean that every model, engine, and control module from that manufacturer is supported.

Some newer control modules may require:

• A control module unlock procedure

• A control module service procedure

• A security access cable

• A make- or model-specific OBD-II adapter
