MegaSquirt® Forums

There are a number of MegaSquirt® forums (they all started at, but our needs and volume grew beyond one set of forums in September 2006). Currently the forums are: Educational, development, and research on the base B&G MegaSquirt® code and hardware. This was the original forums, but has been 'down-sized' considerably to make information and support easier to find. This board is primarily for support of the DIY oriented MS-I™ and MS-II™ processors on V2.2 or V3 main boards. Dedicated forums for MicroSquirt® users who are looking for details specifically about MicroSquirt® EFI controllers (which are smaller, fully assembled controllers using surface mount technology components and printed circuit boards compared to the DIY oriented MS-II™ controllers on V3.0 main boards). Dedicated forums for GPIO board applications, such as the MShift™ transmission controller, and GPIO board assembly assistance. Success stories for users of all variants of MegaSquirt® controllers who have successfully used MegaSquirt® on their vehicle, or who want to document their MegaSquirt® project, Specialized MegaSquirt® user groups based on location, application, or specific interests,

The rules for all B&G forums above are here: B&G forum rules. Be sure to read them, they may not be the same as other forums you have used.

www.MSextra.comForum for users of the msextra code variants as well as all support for the MS3 EFI hardware (i.e. not the V3 main board, the controller called the MS3).
