Hello I have seen an adapter for the ms2 on ebay and am guessing a forum member makes these. I plan on redoing all the wires in future but would love a plug n play unit just to start learning the program. I haven't bought it yet but am buying the megasquirt 3 with extension soon. I have a 2nd gen 1986 s4 n/a with a bridgeported 13b efi engine, only difference to stock is i plan on using my aem wideband instead of reg 02 sensor and maybe in future something diff than stock fuel pressure regulator when I start really modding besides removing fuel pressure dampener. thanks -seth
