SymTech Lab’s Intelligent O2 Sensor Simulator (iO2SS) can eliminate annoying, and sometimes performance-robbing, check engine lights by generating a proper downstream oxygen sensor signal.

EFI Analytics' MegaLogViewer MS is the standard data viewing and analysis software for MegaSquirt EMS. This license unlocks all of the features available in the registered version, including scatter plots, file comparisons, trail mode, calculated fields, custom fields, easier navigation, an ignition log viewer, and more.

Use this MAX9924-based module to add a cam signal from a VR sensor to your MegaSquirt ECU. Cam signals are usually required for sequential coil-on-plug (COP) ignition and sequential fuel injection applications. This module can also be used to condition the signal from nearly any type of pulse generating signal sensor (vehicle speed sensors, wheel speed sensors, etc.).
