What is VCM Suite?
VCM Suite is not your traditional handheld device or programmer - it is much more powerful. It is a comprehensive tuning tool for late model EFI (electronic fuel injection) controlled vehicles that was designed for everyone from the casual beginner to the advanced dyno tune shop or race team. It allows performance tuning and scanning (data logging) of the many parameters that control the operation of the engine and transmission. Whether your desire is to increase the fuel economy of your daily driver or take a twin turbo LS1 down the quarter mile in 9 seconds, VCM Suite is the tool you need to tune your vehicle.
A typical late model vehicle uses computers to control all aspects of the engine (and in many cases the transmission) operation. Some examples of important parameters that VCM Suite can scan/log and change are:
What many people don't know is that your modern vehicle controller also includes various protection mechanisms designed to prevent abuse and premature component failure. These features are of little value in many applications. Some examples are:
VCM Suite gives you complete control over the various facets of performance tuning. In addition, it does not overlook the simple (and often forgotten) things such as changing cooling fan operation, recalibration of speedometer for final drive ratio changes, disabling of anti-theft systems for retro installs to name a few. Regardless of your application, VCM suite covers all the main parameters to tune your vehicle and remove any artificial "power robbers" that decide the 60 foot mark is where your 11 second pass should end.
Just as in the days of carbureted engines, knowing what to change is only half the story. Being able to accurately and conveniently record data that reflects the current state of your car's tune is paramount to any tuner's ability to extract that "extra little bit." VCM Suite includes comprehensive scanner capabilities that allow you to record important parameters while the engine is running. Important parameters such as RPM, spark advance, inlet air temperature, coolant temperature and more can be logged, saved and reviewed to determine how well the current tune is functioning. Add to this the ability to directly incorporate Wideband O2 (A/F ratio), Exhaust Gas Temperature and other sensor readings directly into the data stream via the optional Enhanced I/O (EIO) cable hardware and you have a complete tuning tool that will help you achieve optimum results at the track or on the street.
What is a VCM (Vehicle Control Module)?
In this context we use the term Vehicle Control Module (VCM) to mean the control module that is primarily responsible for engine and transmission operation. In some vehicles there are actually two modules: an Engine Control Module (ECM) and a Transmission Control Module (TCM). In general, the number of modules required to be read or written will be transparent to the end user or become obvious during the reading/writing process.
Generally, vehicles contain many other modules that control different aspects of the vehicle's operation. VCM Suite does not currently allow modification of any of these other modules. Some examples are: Body Control module (BCM), Anti-lock Braking System (ABS) module, Instrument Panel Cluster (IPC), Active Handling module, Radio module, Heater, Ventilation and Air Conditioning (HVAC) module, and Navigation system module.
