With the Boost Control License for the MFD28 and MFD32 you can use your data display to control a clock valve via PWM. You can assign a fixed timing or adjust the timing depending on other sensor values. There are up to four user tables available on the display for this function, so you can regulate the open loop boost pressure depending on, for example, the accelerator pedal position, speed and gear. When you have placed your order: 1. Send the serial number of the device to be used to info@speeding.nu (It shows when starting up the device.) 2. Add your order number 3. We will get back to you with information asap.
