I have a 87 CRX HF with Carb. I would like to change to fuel injection (option on SI model) and MegaSquirt to control fuel and spark.
I want to tune the car for best MPG currently I get 38-44MPG.
I know every one is going to say read the FAQ and manual but I get page not availible error. I started reading messages here.
Any sugestions as were to start ? I can get an intake and injectors from an SI model but what about other sensors?

really need to start at http://www.megaquirt.info If its down, wait for it to come back up. There's way too much you need to know that cant be put into a post on these forums...
