Don't know who all here are using Megasquirt products. I've been using MS3.57X for about 2 1/2 years now. This is full sequential fuel and LS coils from a truck.
It runs great and gets around 30 mpg on the highway and 24 around town.
PM me if you are interested in a copy.

Helped my friend do MS3 on his 300zx. Great system.
