DIYAutoTune MegaSquirt Gen 2 plug-and-play engine management systems are standalone units designed as direct-fit, factory ECU replacements offered for a variety of foreign and domestic vehicles. These powerful and cost-effective options typically require an hour or less for installation, and each includes a base map to get the motor fired up easily and ready for fine-tuning to match your engine's needs--from mild to wild. MegaSquirt Gen 2 ECUs get the job done with an impressive feature list that will let you do a lot more than you'd expect anywhere near this price point. DIY AutoTune MSPNP Gen 2 ECUs typically feature: * Fully plug-and-play installation--no wiring required for basic functionality * Base map is pre-loaded to help your engine start on the first turn of the key * Real-time tuning and data-logging with a laptop connection * Supports most aftermarket wideband sensors * 16 x 16 fuel tables allow high-resolution tuning * 12 x 12 ignition tables * Multiple acceleration enrichment strategies * Closed-loop idle speed control * Air conditioner control * Onboard peak and hold drivers support both high and low impedance injectors--no external ballast resistor is needed * Allows removal of stock airflow meter or stock MAF sensor, if so equipped * 12 x 12 air fuel ratio target tables for use with wideband oxygen sensor for precise tuning and table trim * Built-in 2-step rev limiter/launch control with flat shift * Real-time barometric correction * Internal 4-bar MAP sensor reads up to 44 psi of boost * Over-boost protection * Closed-loop boost control (requires boost solenoid kit) * Knock sensor input with adjustable sensitivity * Headphone output for knock sensor--listen for knock while you tune! * Table switching input--change fuel and spark maps on the fly for different fuels, nitrous activation, etc. * Input for flex fuel sensor--switch between E85 and gasoline on the fly! * CAN Bus connector allows interconnection of other MegaSquirt-compatible devices for additional functions, like: EGT input, automatic transmission controller, additional sensors ... the possibilities are limitless! * MegaSquirt Gen 2 plug-and-play ECU * MSPNP RS232 serial tuning cable, 6 ft. (USB adapter sold separately, if needed) * Tuning software and documentation USB stick * 6 ft. vacuum hose for MAP signal and "T" fitting * Four screws for ECU mounting

The versatile DIYAutoTune MicroSquirt Standalone Engine Management System with 8 ft. harness is an entry-level, fully assembled ECU and universal 30 in. pigtail with varied applications—targeting powersports, single cylinder all the way up to 8 cylinders with up to two fuel and four spark outputs. Over 40 different ignition modes are supported—from mainstream applications like GM LS1, Ford Zetec, Bosch Motronic, and Chrysler Gen III Hemis … to unusual modes like Renix Jeep and the Suzuki Swift GTI. MicroSquirt ECU hardware features: * 2 high impedance injector outputs; max peak current 4.5 amps * 2 dedicated spark outputs * 2 general purpose on/off outputs; can be repurposed as spark outputs * 1 PWM IAC output; can be repurposed as general purpose output * 1 dedicated fuel pump output * 2 variable reluctor conditioned inputs * 1 optoisolated RPM input * 1 flex fuel or general purpose switched input * 7 analog inputs MicroSquirt ECU software features - Supports speed density, alpha-N (TPS based), or MAF based fuel and spark tables - 0.66 microsecond injector pulse width resolution - Allows blending multiple load types, including specialized mode for independent throttle bodies - Supports a wide variety of OEM cam and crank position sensors - Accelerator pump or model-based acceleration enrichment - Closed or open loop idle speed and boost control - On/off nitrous control - Wankel rotary support: 2 rotor engines with separate leading and trailing spark tables - Staged injection - Table switching - 16 x 16 fuel tables - 12 x 12 spark tables - 2 step rev limiter (launch control) with no-lift shifting - Wideband AFR target table - Flex fuel sensor input - Real time barometric correction (external sensor required) - Sequential shift cut and air shifter control MicroSquirt with 8 ft. Harness Transmission Control Options: * MicroSquirt transmission control-free firmware allows you to use MicroSquirt with 30 in. harness to control a number of electronic automatic transmissions (gearboxes). It can work standalone or integrate with one of DIY's ECUs over canbus. * Control applications: GM 4L60E I GM 4L80E I GM 4T40E I GM 5L40E (dev) I A341E I 41TE (dev) I Ford 4R70W I Ford E40D (dev) I Subaru W4A33 and more. MicroSquirt with 8 ft. Harness CAN I/O Box Expansion: * Microsquirt I/O Box firmware allows you to use a Microsquirt as a plug-n-play I/O extension box for MS3 or MS3Pro ECUs. It can offer a useful I/O addition: - 7 Analog inputs (0-5 V variable) - 2 Wheel speed inputs (VR or hall type) - 2 Wheel speed (hall type) or ground-switch inputs - 1 dedicated ground-switch input - 2 high current PWM/switch ground-switching outputs - 4 mid current PWM/switch ground-switching outputs - 1 low current PWM/switch 0-12 V output - Perfect for capturing and logging vehicle speed and additional sensor data
