Summary of change:
I have a 1967 Chevy C10 pickup which I would like to convert to electronic fuel injection. http://www.ices.utexas.edu/~cell/images/c10.jpg The engine in question is a 292 cubic inch inline 6 cylinder -- a somewhat rare motor. http://www.ices.utexas.edu/~cell/images/292.jpg ---- VEMS or MegaSquirt? My decision to use VEMS over MegaSquirt is twofold: * I already have experience with Atmel AVR microcontrollers * I know C ---- Manifold As there was no version of this engine (that I am aware of) which came with fuel injection, there is no existing manifold which supports port injection. There is the option of purchasing a performance manifold which can mount a 4 bbl carburetor, onto which a tbi assembly could be mounted. However, I have no desire to spend $300 on an intake manifold. I will be taking a welding course in march (8 weeks from now), at which point I will be able to fabricate my own manifold. This will tie nicely into a book I am reading, "The scientific design of intake and exhaust systems". My plan is to make a tuned intake for optimum highway efficiency. ---- Use existing manifold? Well, it turns out that 1bbl fuel injection throttle bodies do exist, which means I may be able to get this project off the ground using my existing manifold. According to the [http://en.wikipedia.org/wiki/GM_Iron_Duke_engine#Tech_IV wikipedia page on the iron duke], the GM 2.5L inline 4 was fitted with a single injector 1bbl throttle body which had many applications in the 1980's. At first glance, the mounting gaskets appear to indicate this may be a simple bolt-on solution: http://www.ices.utexas.edu/~cell/images/c10-gasket.jpg http://www.ices.utexas.edu/~cell/images/lumina-gasket.jpg Time to hit up the junk yards and get my hands on one so I can take some measurements. ---- Post Injection Vaporization started a page (PostInjectionVaporization) to discuss implementing this.
Optional: Add document to category:
Wiki formatting: * is Bullet list ** Bullet list subentry ... '''Bold''', ---- is horizontal ruler, <code> preformatted text... </code> See wiki editing HELP for tables and other formatting tips and tricks.
