The PC-V has a reduced size from PCIII usb (less than half of the size of PCIII) Gear and speed input to allow for map adjustment based on gear or speed Analog input allows user to use any 0-5 volt sensor and build an adjustment table based on input such as boost or temperature -100 to +250 fuel change range wich allows more adjustment range for 8 injector bikes 10 Throttle position columns (up from 9) You can switch between 2 maps "on the fly" and maps can be adjusted on a "per gear" basis ( one map per cylinder, per gear, if required) Allows for adjustment of fuel and timing based on engine temp through the "cold start feature" Will power up with USB cable only for programming purposes Perfect for forced induction applications Comes with a Bosch 3 bar MAP/Temp sensor as part of the PCV harness for expanded capabilities built into the control center software Gives you the ability to modify your fuel curve based off a pressure (boost) table and/or temperature table The pressure table gives you 3D mapping capability based on boost vs RPM, while the temperature table gives you 2D mapping capability with up to 50 points of adjustment Perfect for turbocharged or supercharged applications looking for precision, control, and reliability
