Schematics

• MegaSquirt IRLZ44 FET Idle Valve & Solenoid Spare Drive Schematic - PWM Boost
  This document contains two electronic schematics related to MegaSquirt engine management installations, apparently comparing idle valve / solenoid drive circuit options. The left schematic shows an IRLZ44 MOSFET driver…
• TIP120 vs IRLZ44N Pinout & Specs - MegaSquirt PWM Idle Valve Driver Schematic
  This is a composite reference image comparing two transistors and showing a related driver circuit, uploaded as electronics reference material for an engine-management (MegaSquirt-style) project. The left panel is a…
• TIP120 vs IRLZ44N Pinout & Specs - MegaSquirt PWM Idle Valve Drive Schematic
  This document is a composite reference image comparing two transistor options, the TIP120 NPN Darlington transistor and the IRLZ44N N-channel power MOSFET, alongside a solenoid/spare drive schematic (typical of…
• Opto-Isolated Tach/RPM Input Schematic (4N25) - 5V & 12V Mods, Subaru COP Swap
  This document is an annotated electronic schematic showing an RPM/tachometer input circuit built around a 4N25 opto-isolator (U3). The signal path runs from a TachIn input through a TachSelect jumper and an OptoIn…
• Subaru COP Tach Input Adapter Schematic - NTE192/2N5551 High Voltage Tacho
  This hand-annotated schematic shows a tachometer input adapter circuit for use with a Subaru coil-on-plug (COP) ignition setup and a MegaSquirt-style ECU. The Subaru ECU's 12V pulse signal from cylinder #1 (taken from…
