Mitsubishi Outlander owners often discuss modifications and performance enhancements on online forums. One common topic revolves around the limitations of the original inverter in the Outlander’s powertrain system. This post delves into a user’s experience with modifying a similar setup in a Triumph Spitfire and the insights gained, which could potentially apply to the Outlander’s system.
The original poster encountered several limitations with a generator-motor and inverter setup mirroring the Outlander’s. The maximum RPM was capped at 1000 in one direction and 6000 in the other. Furthermore, the phase current peaked at 230 amps, resulting in a torque output of only 70Nm. While functional in a lightweight car, this setup proved inadequate for optimal performance, requiring first-gear starts and limiting top speed due to the motor RPM constraints.
Another challenge arose when using a 96s battery pack. The inverter, originally designed for an 80s battery, refused to operate with the higher voltage. This issue was resolved by modifying the battery measurement resistor array to trick the inverter into recognizing the 96s battery as an 80s equivalent. This workaround highlights potential compatibility issues when upgrading battery systems.
A significant breakthrough came with the implementation of an openinverter firmware. This upgrade unleashed the full potential of the motor, enabling phase currents of 400-500 amps and eliminating the RPM limitations. The improved performance allowed for second-gear starts and significantly higher speeds, eliminating the need for frequent gear changes.
This experience suggests that the Outlander’s original inverter might possess untapped potential. Further investigation within the Outlander Forum community could reveal methods to enhance performance without replacing the entire system. Exploring topics like custom firmware or adjustments to internal settings might yield similar improvements in power and RPM capabilities. While attempting to run the inverter on the motor output yielded minimal results in this specific case, further experimentation and knowledge sharing within the Outlander forum could uncover hidden potential within the factory system. This user’s journey provides a valuable starting point for Outlander owners seeking to optimize their vehicle’s performance.
