PATCHED PCMscan 5.9 - soft for ELM327




If you are looking for a powerful and versatile tool to scan and diagnose your vehicle's performance, you may have heard of PCMscan, a generic OBD-II scanner and diagnostic software that supports a wide variety of OBD-II hardware interfaces. But did you know that there is a patched version of PCMscan 5.9 that offers more features and benefits than the original one? And did you know that you can use it with an ELM327 device, a programmed microcontroller that translates the on-board diagnostics (OBD) interface found in most modern cars?




PATCHED PCMscan 5,9 - soft for ELM327



In this article, we will explain what PCMscan and ELM327 are, what they do, and how they work together. We will also show you how to install and use the patched version of PCMscan 5.9, which is also known as soft for ELM327, and what features and benefits it offers. By the end of this article, you will have a clear idea of how to use this tool to scan and diagnose your vehicle's performance, troubleshoot problems, and optimize your driving experience.


What is PCMscan and what does it do?




PCMscan is a fully featured generic OBD-II scanner and diagnostic software that supports a wide variety of OBD-II hardware interfaces. It allows viewing, charting, logging, and playback of diagnostic data in real time via the vehicle's OBD-II diagnostic data port. It also allows viewing of vehicle Diagnostic Trouble Codes (DTCs), Freeze Frame data, and other vehicle information.


PCMscan supports all vehicles that are OBD-II compliant, which means most cars sold in North America since 1996, as well as some European and Asian vehicles. It supports various OBD-II protocols, such as SAE-J1850 (PWM and VPW), ISO-9141, ISO-14230 (KWP2000), ISO-15765 (CAN), SAE J1939 (250kbit/s), SAE J1939 (500kbit/s).


PCMscan enables you to monitor various parameters of your vehicle's performance, such as engine RPM, coolant temperature, fuel pressure, oxygen sensor voltages, throttle position, timing advance, intake air temperature, air flow rate, etc. You can also perform virtual dashboards, drag strip tests, dyno tests, data logging, freeze frame data analysis, trouble code reading and clearing, vehicle information retrieval, performance tracking, etc.


What is ELM327 and how does it work with PCMscan?




ELM327 is a programmed microcontroller produced for translating the on-board diagnostics (OBD) interface found in most modern cars. The ELM327 command protocol is one of the most popular PC-to-OBD interface standards and is also implemented by other vendors.


The ELM327 abstracts the low-level protocol and presents a simple interface that can be called via a UART, typically by a hand-held diagnostic tool or a computer program connected by USB, RS-232, Bluetooth or Wi-Fi. The ELM327 can also be used to implement an interface compatible with the OBD-II standard.


The ELM327 works with PCMscan by acting as a bridge between the OBD-II port of your vehicle and the software running on your computer. You can connect the ELM327 device to your vehicle's OBD-II port using a cable or a wireless connection, and then connect it to your computer using a USB, RS-232, Bluetooth, or Wi-Fi connection. The ELM327 device will translate the OBD-II signals into a format that PCMscan can understand and display on your computer screen.


What is the patched version of PCMscan 5.9 and why is it useful?




The patched version of PCMscan 5.9, also known as soft for ELM327, is a modified version of the original PCMscan 5.9 software that offers more features and benefits than the original one. The patched version of PCMscan 5.9 is not an official release from Palmer Performance Engineering, the developer of PCMscan, but rather a result of reverse engineering and hacking by some enthusiasts who wanted to improve the functionality and compatibility of the software.


The patched version of PCMscan 5.9 is useful because it allows you to use PCMscan with any ELM327 device, regardless of the firmware version or manufacturer. The original PCMscan 5.9 only supports ELM327 devices with firmware version 1.3 or higher, which means that some older or cheaper ELM327 devices may not work with it. The patched version of PCMscan 5.9 bypasses this limitation and makes PCMscan compatible with any ELM327 device.


The patched version of PCMscan 5.9 also offers some additional features and benefits that are not available in the original PCMscan 5.9, such as:


  • Support for more OBD-II protocols, such as ISO-15765 (CAN) 11bit/29bit 250kbit/s/500kbit/s



  • Support for more vehicle parameters, such as fuel level, fuel consumption, fuel trim, etc.



  • Support for more virtual dashboards and gauges, such as turbo boost, oil pressure, oil temperature, etc.



  • Support for more drag strip and dyno tests, such as 0-60 mph, 0-100 mph, quarter mile, etc.



  • Support for more data logging and playback options, such as CSV export, graphing, etc.



  • Support for more freeze frame data and trouble codes options, such as live data display, code description, code clearing, etc.



  • Support for more vehicle information and performance tracking options, such as VIN decoding, engine hours, distance traveled, etc.
