Hi everyone long story short my 1982 280zx turbro needs a new afm which i do not want to buy and would rather megasquirt, only question is which one should i buy? ms1 2 or 3? im keeping everything stock (besides megasquirt) so not sure if i really need ms 3 any suggestions?
Thanks a bunch

 

I like the MS3 because it has a lot more flexibility than the MS2 and there isn't a huge jump in price.

 

...and... I'm just building a MS2 for a friend. The MS2 doesn't support USB so it's serial which is a pain compared to the USB interface....
