Hello all,
I am a newbie to this message board but have found it to be filled with a great deal of knowledge. There seems to be a plethera of interesting projects going on here!! I have had plenty of experience with fuel injection systems in the auto world, but have never designed and built anything from scratch before. I looked throughthe archives and found quite a bit of usefull information, but thought I would ask a few questions.
I am working on a VERY basic fuel and ignition control project. I am trying to do this with as few inputs as possible to keep costs down. My thoughts were to use a Motorola 68HC11 as the basis for this system mainly because I have experience with them, but also because it has everything I need on a single chip!!! I obviously need the crank position sensor, but do I need the cam position as well? If not, how do I make sure what stroke I am on and if I need to either spark or inject? Here is the catch; I want to try to get away without using a MAF for this system. Can I do a pseudo speed density setup with just an intake air temp sensor? Also, my application doe snot need to meet any emissions standards as of right now. I am not planning to use an O2 or an EGT. Can you think of other inputs that may be absolutely necessary? I want to minimize component count and cost, as well as board space.
I would appreciate input from anyone out there who may be able to help me on this project!
