DiabloSport inTune i3 Platinum 8345 Performance Programmer with PCM Swap – Dodge, Chrysler & Ram HEMI

Vehicle Compatibility and HEMI Applications

The DiabloSport inTune i3 Platinum 8345 is marketed for supported Chrysler, Dodge, and Ram performance applications. However, exact fitment depends on model year, PCM architecture, engine, and transmission.

Important fitment notice: The supplied 2004–2014 year range is not a confirmed universal fitment range for every listed vehicle or engine. Part #8345, PCM swap requirements, and supported model years should be confirmed against DiabloSport’s current application guide before purchase. Not every model or year requires the same PCM procedure.

Dyno-Tested HEMI Performance Tuning

Increase Horsepower and Torque With Optimized ECU Calibrations

The factory PCM manages essential engine operating parameters, including ignition timing, fueling, electronic throttle behavior, and other vehicle-specific functions.

The DiabloSport inTune i3 Platinum provides access to compatible performance calibrations developed to optimize these settings for supported engines and fuel grades.

Depending on the vehicle and selected tune, performance tuning may deliver:

• Improved acceleration and throttle responsiveness.

• Increased horsepower and torque within the limits of the supported calibration.

• Revised transmission behavior where supported.

• Improved part-throttle drivability.

• More consistent performance with compatible modifications.

Actual horsepower gains depend on the engine, fuel octane, vehicle condition, environmental conditions, and calibration. Performance improvements and fuel-economy gains are not guaranteed.

Easy Tune Mode: Customize Your Driving Experience

The DiabloSport inTune i3 Platinum goes beyond simply installing a performance tune.

Its Easy Tune functionality allows owners to modify supported vehicle parameters without navigating complicated tuning software.

Tire Size and Speedometer Calibration

Changing tire diameter can affect speedometer readings and calculated vehicle speed.

On compatible applications, the inTune i3 allows tire-size adjustments to help compensate for aftermarket wheel and tire combinations.

This is particularly valuable for Ram 1500 owners who have installed larger all-terrain tires or modified their suspension.

Transmission Shift Optimization

On supported automatic-transmission applications, the inTune i3 may provide access to transmission-related settings such as shift points and shift firmness.

These adjustments can help tailor drivetrain behavior for everyday driving or performance applications.

Transmission tuning availability depends on the vehicle and calibration. Some Chrysler applications require additional transmission-controller support.

Speed and RPM Limit Adjustments

Supported vehicles may allow adjustments to engine rev limits and speed-limiter settings.

These settings should only be changed when appropriate for the engine, tires, drivetrain, and intended operating conditions. Increased limits do not increase the mechanical capabilities of the vehicle.

OBD-II Diagnostics and Engine Data Monitoring

One of the most useful features of the DiabloSport inTune i3 Platinum is its ability to combine performance tuning with basic engine diagnostic functions.

The handheld device can read and clear supported diagnostic trouble codes, making it useful when troubleshooting Check Engine Light concerns before or after tuning.

For example, incorrect fuel delivery, vacuum leaks, sensor faults, or ignition problems can affect engine performance regardless of how well a vehicle is tuned.

Understanding Fuel Trims Before Tuning

Short-Term Fuel Trim (STFT) and Long-Term Fuel Trim (LTFT) are important indicators of how the engine management system is correcting fuel delivery during closed-loop operation.

Monitoring these values with suitable diagnostic equipment can help identify problems such as intake leaks, inaccurate airflow measurements, or fuel-delivery issues.

The availability of specific live-data parameters, including fuel trims, depends on the vehicle and firmware. The i3 is not a substitute for professional diagnostic equipment or wideband air-fuel monitoring during advanced custom tuning.

PCM Swap and Unlock Requirements Explained

Certain late-model Dodge, Chrysler, and Ram vehicles use protected PCM architectures that restrict aftermarket calibration changes.

For these applications, performance tuning may require a compatible unlocked PCM or a manufacturer-supported PCM modification process.

The DiabloSport inTune i3 Platinum can be part of this tuning process, but the handheld device itself does not automatically unlock every factory PCM.

Before purchasing: Confirm whether the specific vehicle requires a PCM swap, PCM unlock service, security bypass module, or additional hardware. Do not assume these components are included with part #8345 unless they are explicitly identified in the seller’s package contents.

Easy OBD-II Installation and Tuning

For supported vehicles with a compatible PCM, the inTune i3 connects through the standard OBD-II diagnostic port.

The general tuning process includes connecting the device, identifying the vehicle, selecting a compatible calibration, and following the on-screen instructions.

Before programming, ensure the vehicle battery is properly supported, use the fuel octane required by the selected tune, and never disconnect the device while the PCM is being programmed.

Unlike an inline throttle controller, the inTune i3 changes supported ECU calibration data. Factory settings may be restorable through the device, but tuning history and warranty implications can remain.
