And the serial RS-232 signals come out of the AMPSEAL connector (instead of a DB-9 on the front, as with MicroSquirt®). The bootloader is externally accessible, so there’s no need to open the case, even to load new code.

You can still upgrade to newer versions of the code as they are released, of course, but you won’t have to load the code initially to get MicroSquirt® working. Pre-loaded code: Unlike MegaSquirt®-II, MicroSquirt comes with the embedded code already loaded onto its processor.

MicroSquirt’s® board size, including the 35-pin AMPSEAL connector, is very small – 2.4″ x 3.5″ (61mm x 89mm), just slightly bigger than a credit card. Amazingly, the board is the physical size of a business card – connector and all. The MicroSquirt® board uses the 35-pin AMPSEAL connector and a sealed case to make a fully sealed unit. PWM Idle valves, as well as on/off idle valves, can still be used.ĭifferent connector and case. No stepper IAC control: In order to make room for the dual ignition inputs and dual outputs, the ability to to control a stepper IAC was removed. See the MicroSquirt® hardware page for more information on MAP sensors. An external MAP sensor, such as those from General Motors products, can be used instead. In order to shrink the ‘footprint’ of MicroSquirt®, the MAP sensor was left off the board. For example, for motorcycle use MicroSquirt® will be perfect! For up to 4 high-impedance injectors per bank. This is not a ‘peak and hold’ driver, but it does clamp the current at 5 amps, so it can be used with one low-impedance injector per bank, however the close time may be a tad higher (or you can use resistors). To get everything to fit without lots of heat sinking, MicroSquirt® uses the ST VND5N07 from STMicroelectronics to drive the injectors. The fuel injector drives will max out at 5 amps each, enough to drive one low-impedance (or 4 high-impedance) injector per bank. No pulse width modulation (PWM) to limit injector current.

Non logic level coils can be used with the addition of EFI Source coil driver Part # CI-101.ĭual Spark capability: The major new feature in MicroSquirt® v2.822 embedded code is the capability to use two inputs and two outputs for ignition.

The coil drivers have been eliminated from this version and Ignition outputs are logic level only. The New V3 MicroSquirt® has a waterproof case as well as adaptive noise filtering on the VR circuits. Trying to estimate what your engine will specifically need beforehand can be more confusing than productive.MicroSquirt® V3 with 8 ft harness is a fully-assembled surface mount technology (SMT) version of the MegaSquirt® fuel injection controller. In general, this is all much easier to understand when you are working on a running engine. Also see the code specific tuning parameter's guide for the code you are running, such as those for 2.905 or 3.770 Not doing so can cause damage to your engine. The most fundamental parameters are in the 12×12 volumetric efficiency (VE) table(s), the 12×12 air/fuel ratio (AFR) table(s), and the 12×12 spark advance table.īe sure to read all of this document, and the configuration document BEFORE starting to tune your engine. These include things like cold start pulse widths and acceleration enrichments. Tuning involves setting all the parameters that the MegaSquirt-II™ (or MicroSquirt®) controller uses to be optimal for your non-pollution controlled engine, injection components, and driving style. If you are not familiar with tuning EFI systems, you might want to review the material in the Principles of Tuning page before reading this document.
