MS1/Extra - MS2/Extra - MS3

Introduction

The developers of MSEXTRA and MS3 have invested hundreds of hours in coding and supporting the Megasquirt firmwares to deliver what our users are requesting. If you appreciate our work, you may wish to make a voluntary contribution.

Bruce Bowling (Megasquirt founder) noted "We (B&G) "give" the major developers of megasquirt items like extra hardware in order to implement and test code, and $$$s to purchase needed tools (i.e. server space to support this forum, for instance). Also we give a very small amount of dollars to them* as funds dictate - which then gets sucked right back into MS.
Let me say that the absolute tiny amount of money made is by no means even close to any sense of real payment with respect to the astronomical amount of time and effort put forth by the developers. Let me make it clear that MS is not a profit center by any sense of the word, anyone thinking otherwise needs a real education. We (B&G, resellers, etc) are not getting rich or rolling in $$$s - in fact it right on borderline break-even and losing ground everyday."
* "Them" is James Murray, Kenneth Culver, Philip Ringwood and Philip Tobin

MS2/Extra

The MS2/Extra firmware took the original MS2 B&G and extended it with the features from MS1/Extra. Every-tooth wheel decoding, a whole host of OEM wheel patterns, up to six spark outputs, EAE fuel enrichment, switchable tables, closed-loop idle, boost, nitrous control, built-in tooth analyser, increased precision in calculations.
Most recently 4 cyl sequential fuel control was added.
