What do all the version numbers mean for the hardware and code(s) for MegaSquirt?
A. Right now there are two processors for MegaSquirt: • 68HC908 was used on all MegaSquirt® EFI Controllers up to 2005, and many after it. It is a discrete 40 pin IC (integrated circuit – aka. ‘chip’). It will run the standard MegaSquirt® code, • MegaSquirt-II™ add on daughter card replaces the standard 68HC908 microprocessor and allows the controlling of ignition advance and stepper motor idle air controllers (IAC), as well as having 12×12 tuning tables (for both fuel and ignition), and a number of other features. You can find out more here: www.megamanual.com/ms2/ There are 6 versions of the MegaSquirt® main board (PCB) in service: • V1.01 DIY main board from the first group buy in 2001. These are no longer available, • V2.2 DIY main board from the second group buy (2002) and all sales until July 2005 (they can be identified because they are primarily green, and have V2.2 printed in the top left corner), • V3 DIY main board that has a number of extra features specifically designed fo
