Week0 Narrative

 * This week two of my teammates and I were assigned the ECU project for our Project 1. ECU stands for Electronic control Module. Our team started by watching the video given to us by the professor, This weekend we are going to be watching video |ECU Tuning Technology, this help my teammates and I understand what we doing dealing with.
 * Professor Forester has assigned me to be in charge of the group and try to get to the next step. We obtained ECU's from wheelchairs and will see what we can do with those. I will also try to gather my team and go to crazy rays to grab an ECU out of an old car. This weekend we are going to have separate tasks that include searching videos, begin 3rd document coder, and one person to start flidling with the wheelchair ECU we obtained in class.


 * I will start looking into my first project and try to find the next steps of the ECU project. I will bring my OBD connecter to school, a device that reads the computers in cars most commonly used to read engine lights.If you want to see how it works visually, watch the video | Reading and Understanding a CEL. Ironically a part time car dealer, I have one of these readers in hand. Will now try to find the next step, and with myself being the team leader, this should get interesting.
 * CEL = Check Engine Light

Week1 Narrative

 * My partner and I Sarah have been working solo as out third team member is a no show. This week I headed to the car, gathered all my tools, dismounted the ECU, striped all the wires, unplugged all the sensors, and brought what I removed to my lab in CL158.
 * This took about two hours and it was tough to work in the space provided, plus the neighbors thought I was crazy. Ended the evening by documenting my experience.
 * The next day I starting watching how to videos such as | How to reflash your ECU. This demonstration shows you how to alter your ECU to do things such as add horsepower, or even boost performance on other parts of the car. The ECU is the brain of the car.

P.S. - When I started the project,the OBD Auto Scanner did not read any codes, therefore the ECU did not emit any Check Engine Lights at the start of this project.

Week2 Narrative

 * Started off the week by presenting to the class about my findings thus far. My next step is to color coordinate the 50 or so wires down to the 5 wires that are connected to the OBD connecter end. The other 45 wires must go to the hundreds of sensors around the car, which I will not be using. I will temporarily leave the wires on the plugs for now until I have to take them off.
 * The five wires that are connected to the OBD connector head and the 7 or 8 wires that are connected to the plugs on the back of the ECU all have stripped ends now as I cut off the plastic wraps on their ends. I obtained two power lines from the car, both about one foot long, one of them is black and one of them is red. They are thicker than normal. I will finish up this week by opening up the ECU shell and try to figure out how I will be able to add power to this source.
 * Opened the ECU box but looks all too confusing. I found a ECU wiring diagram online which I have to carefully read and understand a little more. The website is called ECU Wiring Diagram for a 1996 Isuzu Hombre.
 * Next step is to add power to the ECU, before connecting the plugs to the OBD connector....

Week3 Narrative

 * The next step is to buy a | ECU Simulator which allows you to test a ECU by using the simulator as fake car.


 * This should get interesting...


 * This will not work now as it does not resolve the purpose of our problem.


 * Will now continue to find a power source for the ECU, and start to put together the ECU this weekend in respects to the wiring.

Week4 Narrative

 * So there are three plugs that go into the ECU that are colored Blue, White Black. There are a total of 54 wires coming out of the plugs and the online diagram I found of that ECU Wiring diagram only stated 45 wires. Between the physical 54 wires and the 45 documented wires, there were 9 wires that were missing on the diagram. The OBD connector plug has 5 wires that I need to connect. I color coordinated those five wires and now have 11 possible wire combinations that would work.

 File:ECU Wiring Diagram.JPG|ECU Wiring Diagram. 54 physical wires, 45 documented wires. 9 physical wires missing from the diagram. Highlighted the ones I found that I need to connect to the OBD connecter. 
 * Out of the possible 11 wires, 4 of them were not found on the diagram (out of 5 total). Out of 54 wires, the 4 that I need out of 5 wires missing of the total is somewhat odd.


 * The wiring diagram can also be found here. ECU Wiring Diagram for a 1996 Isuzu Hombre


 * Next step is to buy a Can Bus on amazon which is a simulator.
