The MicroSquirt and MegaSquirt families of EFI controllers are proven designs. Of course, you can always find room for improvement - that's the entire theme behind using aftermarket controllers!

- Reading the manifold pressure when using ITBs can be tricky. This unit not only returns the lowest pressure reading, it also tells you when your 'index' cylinder is in its intake stroke.
- The MicroSquirt isn't able to control a stepper motor, but this device converts the PWM FIdle signal to a stepper 4-wire output signal.
- The V3.57 Motherboard doesn't allow for much in the way of customization, and some of the functionality of the processors get left by the wayside. This easy to install card allows the use of the JS4, 5, 7, 10, and 12 pins through the DB15 connector.
