Many Mustang EcoBoost owners use the EcoOBD2 forum to discuss performance modifications and diagnostic tools. One common topic is using Forscan Lite on iOS devices to monitor and adjust vehicle parameters. This post explores a user’s experience with Forscan Lite on iOS, focusing on its configuration capabilities and observations regarding intercooler performance.
A user on a popular EcoOBD2 forum reported difficulties accessing the Powertrain Control Module (PCM) using the OBDFusion app on their iPhone. Consequently, they switched to Forscan Lite, seeking to monitor specific parameters, including charge air temperatures, while running a Ford Performance tune. While Forscan Lite successfully connected to the vehicle, the user found their configuration options limited. The question arose whether limited configuration access is typical for Forscan Lite on iOS, especially concerning the ability to adjust the bass rolloff setting.
The user’s primary goal was to monitor charge air temperatures (IAT2) to assess intercooler efficiency. Initial observations revealed minimal temperature differences between the intake air temperature (IAT) and IAT2 sensors, even after highway driving with ample airflow. This led the user to question the stock intercooler’s effectiveness in cooling charge air temperatures. They observed significantly high IAT2 readings after exiting the highway, despite anticipating cooler temperatures due to consistent airflow during the drive.
Charge Air Temperatures After Highway Driving
The user’s experience raises questions about the stock intercooler’s performance in the Mustang EcoBoost. It challenges the assumption that consistent airflow during highway driving sufficiently cools charge air. The observation of high IAT2 temperatures after highway driving suggests potential heat soak issues, even under relatively normal driving conditions. This highlights the importance of monitoring charge air temperatures, especially for tuned vehicles, and potentially upgrading to a more efficient intercooler for improved performance. Further discussion on the EcoOBD2 forum could provide additional insights into these findings and potential solutions.
