Boost Control Mod Kit

Give your MegaSquirt ECU the ability to control a boost solenoid—doubling its power as a programmable electronic boost controller! This Boost Control Mod Kit includes all the components needed to install a boost control output circuit on your V2.2, V3.0, or V3.57 PCB. Compatible With: MS1/Extra MS2/Extra Any MegaSquirt variant that supports external boost control Not required for MS3-Pro, MSPNP, DIYPNP, MS3X, or MicroSquirt—these already have built-in boost control outputs. Kit Includes: Power FET Resistors Mica insulator Heat sink compound Mounting hardware This is the exact boost control circuit we’ve run on our DIYAutoTune MR2 and dozens of customer builds—with fast, reliable switching and excellent solenoid response. Works with most common boost control solenoids (we recommend our EBC Solenoid – sold separately). Why Choose This Circuit? Of the various boost control designs in the MS/Extra documentation, this circuit has been chosen for its universal compatibility and performance. The FET-based output delivers high-speed, consistent switching across a wide range of MS setups.
