MegaSquirt-III is back in stock! Pricing is $195 for a daughter board kit for upgrading an MS1 or MS2 (You'll also need an MS3-specific case), $365 for a V3.0 unassembled kit with MS3 daughterboard, and $540 for a complete MS3 V3.57 (silver case). MS3X expansion boards are $90 each. A complete MS3 V3.57 with MS3X already installed and a black anodized case is $640.
MegaSquirt-III is the latest generation of MegaSquirt hardware from Bowling & Grippo. With a high speed dual core processor, onboard SD card logging, built in USB adapter, and many features requested from the racing world, this takes MegaSquirt to a new level. The MS3X expansion board pushes things even further, allowing you to upgrade your MS3 to have 8 sequential injector drivers, 8 logic level spark outputs, 6 relay / solenoid driver outputs, and more. Plus, the MS3X expansion board will drop right into your MS3 with easy bolt in installation - no soldering required! For more information, see the official MS3 website at ms3efi.com.
The MS3 daughterboard can be installed on V3.0 or V3.57 main boards. It plugs in where the processor or MS2 daughter card would go. We stock the MS3 in kit form with the V3.0 board and ready to go with the V3.57. The two boards are functionally very similar, just the V3.57 is machine assembled.
