MobiSquirt allows you to connect your iOS device to a MegaSquirt ECU, view realtime data from your car's engine control system and log that data for later analysis using available tools such as MegaLogViewer.

MobiSquirt will eventually support all versions of the MegaSquirt firmware but initial versions of the app will concentrate on compatibility with MegaSquirt 1, MegaSquirt 1 - Extra, MegaSquirt 2 and MegaSquirt 2-Extra. It is also anticipated that support for MegaJolt will be added.

Version 1.1 of the App has been tested against most versions of the MS1-Extra and MS2-Extra firmware. Other firmware versions have partial or no support in this version.

Use of this app will require provision of a WiFi connection to your MegaSquirt ECU. Details of suitable options for this are available on the app web site - and in the user manual available at
