Is megasquirt worth it?

[nando]

worth it for the average joe who wants to just put a chip in their car? no, not really

worth it for somebody who is obsessed with having total control over every part of their engine and is willing to learn everything about EFI from scratch? definitely.

for your car, it would be fine. you wont need a knock sensor but if you are going the boost route, you would like it. knock sensor is an option you have to add - there are instructions.
I know youre the type that can figure things out and get through them, this is a management system for you.
