PTC Velocity is a Sales Enablement Platform, powered by SAVO Group. The goal of this project was to revamp the web UI and navigation that result in better user experience.
User Research • Prototyping • UI Design • UI Development
Though its purpose is to enable better sales process, PTC Velocity’s bad UI and poor content organization were not tailored to fit the needs of our daily users, the sales reps and partners reps.
We knew the website refresh needed to start from home. The old homepage did not serve much of its purpose. Randomly placed announcement banners and unclear buttons on top made the homepage to look confusing.
With the this project, we wanted to accomplish following goals:
To learn more about our users’ experience with the current site, we conducted user interviews and usability testing. Based on the feedbacks we collected, we were able to identify 3 major user behavior using this platform.
“When I go into Velocity, I care more about information design than pretty looking UI. As long as I can find contents as quickly as possible, the better.”
Many users struggled navigating through pages to find the right content. We needed to find the best way to make their discovery experience easy and seamless.
The design process consisted of card sorting, information architecture, task flows, and creating low-fi/high-fi wireframes.
Typical wiring/voltage notes
The ECU is typically located in the lower front pillar portion near the front right seat. ECU Pinout and Terminal Overview
The ECU is typically enclosed in a durable metal housing with multiple high-density multi-pin plug connectors. These connectors are split into distinct blocks—often referred to as the Engine Side (Connectors going to sensors/actuators on the block) and the Vehicle/Chassis Side (Connectors handling power, ignition, and dash clusters). Power Supply and Ground Pinouts (Top Connector)
: Features a 32-bit microprocessor with RAM, ROM, and EEPROM to store correction data even when the battery is disconnected. Typical ECU Pinout Functions
Before diving into the pinout, it's essential to clarify a major point of confusion. The search term "Mitsubishi 4M51" can lead you to two completely different systems. mitsubishi 4m51 ecu pinout top
Clean, isolated ground paths reserved strictly for sensitive sensors (e.g., crank and cam sensors) to prevent electrical noise.
While specific pin numbering can vary slightly by manufacturing year, the following components are critically integrated into the 4M51 ECU harness: Fuel Management Spill Valve (SCV)
Signals the internal microprocessor to initialize system boots when the key turns to the "ON" position.
Before diagnosing any sensor or communication faults, you must verify that the ECU is receiving clean, stable power and has a solid ground path. Fluctuations here can throw false diagnostic trouble codes (DTCs). Main Power Inputs Typical wiring/voltage notes The ECU is typically located
Multi-pin male terminal arrays accept a combination of delicate signal pins and heavy-gauge power blades.
A critical safety pin that drops to 0V to halt fuel delivery and kill the engine when the key is turned off or a catastrophic failure is detected. 3. Primary Engine Monitoring Sensors
In this guide, we dissect the top connector (typically a 22-pin or 24-pin rectangular AMP/Tyco or Yazaki connector) pin by pin.
This is why verifying every single wire with a multimeter before making any connection is an absolute necessity. You cannot assume that pin 10 on your friend's 4M51 is the same as pin 10 on yours. Power Supply and Ground Pinouts (Top Connector) :
Are you currently troubleshooting a or performing an engine swap ?
There are several ways to obtain the Mitsubishi 4M51 ECU pinout:
If diagnostic scan tools cannot establish a link, look up your specific engine layout's Scribd Wiring Manuals to verify continuity on the K-Line diagnostic line or the high/low Controller Area Network (CAN) pins. Best Practices for Harness Pin Diagnostics
The ECU processes signals from critical engine components to maintain optimal performance. Key pin assignments typically include: Mitsubishi 4m51 Ecu Pinout
There is never a perfect design! We had a lot of positive feedbacks from our users with the redesign. Users were satisfied with cleaner UI and improved navigational experience.
However, even the new design could not satisfy our users 100%. As they continued using the tool, they faced with new sets of problems. I learned how important it is to never get fully satisfied with the design decisions and the continue the effort of iteration, which should not be an option but a habitual routine.
