MegaSquirt ® and MicroSquirt ® controllers are not for sale or use on pollution controlled vehicles. The board is sealed in a weather proof enclosure. 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. With the app, you can view data display functions, change basic settings, and clear fault codes directly from your smartphone or. 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. The new Haltech Connect is a feature-lite application for both iOS and Android mobile devices that connects wirelessly to Haltech Nexus ECUs for adjusting basic engine parameters and reviewing data in real-time. 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. We have free, accessible start-up maps for a range of vehicles from a 1UZ to a MX5 1.6L engine. ![]() The fuel injector drives will max out at 5 amps each, enough to drive one low-impedance (or 4 high-impedance) injector per bank. The PlugIn ECU engine Start-Up maps are also stored within PC Link meaning you can download maps for any of the PlugIn ECU range we have, plus more. No pulse width modulation (PWM) to limit injector current. Dual Spark capability: The major new feature in MicroSquirt® v2.822 embedded code is the capability to use two inputs and two outputs for ignition. ![]()
