headache

straight to the point, when our project comes to the wiring, i swear it really gives me a big headache. when we took it off the car, we had to cut most of them, there was no way which we could keep them completely. so when we put them on the table, all the components, the ECU and the wire harnesses are seperately in a really big mess. even some of them are not part of our project, but you just have to take them together as well. there is no way you can work them out without a wiring diagram. so we downloaded all the wiring diagram related to EFI system. i have learned the theory before, but when all the wires, ECU and componnets put on the table, you just have no idea how struggle you can be. after consulting with Tony, we determined to start from clearing all the wires first, coz they tangled together. it would be very wise if we labled them and taped them in order when we took them off the car. but now we have to face the fact which we did not do so. we started from the wirs on the ECU, we put them one by one and taped them so it won't tangle with others again. honestly, i even read the diagram wrong when i first tried to work on it. after all the wires are labled and cleaned, we continued to located all the connectors to each sensors.

seriously, even when i am doing all calculations i nerve got headache, but this just keeps me struggling.

process

we basically have all the requirements to start our project. today, we put our EFI components onto a board. Tony and i think it will be a good idear, if we can make the whole system works first, then next semester, we will improve it and make it better. under the concern of friendly evirionmentally and sustainability, we think we will use some kind of fluid which is not flammable and no corrosion ability to injectors to simulate the gasoline spray patterns in the injectors.since we also need to simulate the spark in the spark plug, this is why we can not use gas. as all the componnets in a car, you may never notice how imporant it is of the design of the whole sysem such as how to connect them in a logical way. but once you have to put them on a limited board the location of the many components are critical to the whole project design. before we actually fix them onto the board, we have to swap all the parts all around to get their perfect location.
