Here are some more information for Computer Ecu:

The National Agricultural Research Center (NARC) of Japan has engaged in a robotic project that fully mechanized rice production with a global positioning system (GPS) capability that can painstakingly transplant rice using sensors and computers which can be independent from human activities or the use of human labor. The transplanting machine can make an accurate plan and direction on where to transplant around a six inch long rice seedlings. The rice seedlings are grown over two weeks on a long mat, using hydro-phonics culture system.

The long mat containing the seedlings is unrolled from the machine, and each seedling is sown into the soil, six in a row each time. Twenty rolls of mats weighing a total of two hundred eighty kilograms (280 kg.) are needed to cover a one hectare area. The transplant robotic machine is estimated to cost a farmer for acquisition cost around sixty thousand US dollars (US$ 60,000).

However, the technology is still under evaluation at present. But once proven ready for commercialization, price of the equipment may decrease to accommodate especially the farmers in developing nations where the traditional old methods of rice production are still prevalent.

Mass production of the same can lower the price or cost of the technology. A Controller Area Network (CAN) bus is set up to oversea the activities of the rice transplanter through its Equipment Control Unit (ECU), where all the sensors, motors and a main computer are all connected.

Prior to the transplanting operation of the machine, the four corners of the field and the travel path have to be plotted. During transplanting, the main computer controls actions to minimize the deviation from the desired travel path in accordance to position and direction data. The travel speed of the transplant robotic machine can be revised from the main computer in order to make any adjustments from the deviations of transplanter's path. The main computer commands the robotic to stop at the end o a field, lifts and turns it to the next path. As observed, deviations from the planned path is at ten centimeters.

To measure direction and inclination of the machine, an Inertia Measuring Unit (IMU) that has fiber optic gyro sensors and accelerator is used. The NARC is actually on a six row transplanter that already exists in Japan. Ninety nine percent of rice farms in Japan are already mechanized and even rice transplanting is reportedly in practice by one hundred percent of Japanese farms.

Apparently, Japan's average rice yield is six metric tons per hectare compared to the developing countries of three and a half metric tons only per hectare. Transplanting maximizes land use and cuts weed presence. Japan has its own mechanized rice planter since 1966 yet, but it was dependent with human labor pushing the transplanter while the farm worker's feet are on knee deep on the ground.

With the present GPS system, Japan's rice production may be fully mechanized from land preparation to harvest time. The NARC has proposed that in order to be cost efficient in producing this farm equipment technology, it has to compact the system by combining the sensors and computer segments on a rice transplanter, combine harvester, fertilizer and a tractor segments are shared as the first stage of their plan.

In the next stage, they are planning to develop an autonomous combine harvester using the Controller Area Network (CAN) bus to share with GPS receiver, IMU and a main computer attached to the rice planter.

Eclipse Emissions Testing Procedures And Ecu Replacement

Although an Eclipse ecu replacement is not an easy job, we included information on vehicle emissions testing for the ecu to help you better understand the testing procedure and what the computer test results mean. Vehicle emissions testing requires an expensive piece of equipment called an infrared exhaust analyzer. Some analyzers measure only two gases, hydrocarbons and carbon monoxide (HC and CO), while others measure three, HC, CO, and CO2 (carbon dioxide), or four, HC, CO, CO2, and O2 (oxygen) gases. Carbon dioxide and oxygen are not pollutants, but their level in the exhaust gases can be used for diagnostic purposes  on catalytic converter equipped Eclipse vehicles. Exhaust analyzers cannot read oxides of nitrogen (NOx) levels. Most vehicle emissions checks begin with an underhood visual inspection to see whether any emission control devices have been disconnected or are missing. The inspector may also check the Eclipse gas tank filler neck to see if the unleaded fuel restricter has been punched out so regular leaded gasoline can be used.

The second part of the test involves inserting an exhaust analyzer probe into the vehicle's tailpipe and checking emissions at idle. Some tests also include running the Eclipse engine at  higher speeds, but since pollution levels are greatest at idle, an idle check will usually catch any problems. Each state or metropolitan area is free to set their own ecu standards. The passfail point is usually set low enough so most Eclipse cars pass, but those emitting excessive pollution won't. The standards are determined by the model year vehicle, with standards for older vehicles being more lenient than those for newer ones. If an ecu fails an Eclipse emissions check engine light will activate, it means it is putting out too much HC or CO, or that the inspector found something missing or inoperative during his visual inspection.

In some states, there's a cost waiver that says if repairs bring a vehicle into compliance the law will exceed a certain dollar amount, then the Eclipse will be passed anyway. This is to avoid an undue financial hardship on those who can't afford to keep their vehicles ecu n good repair. Other states have no such waiver. And even in those states that do have a waiver, there is no waiver allowed for eclipse cars that have been deliberately tampered with. In other words, if the inspector finds that you've replaced the catalytic converter with a piece of exhaust pipe or disconnected any ecu control device, the vehicle must be restored to its original condition before it will be passed. Any missing or intentionally disconnected ecu emission control systems must be replaced regardless of cost. Since the specifics of vehicle emissions testing vary considerably from one area to another, we suggest you contact your state department of transportation or environmental control for details. Even if you live in an area where no periodic emissions checks are required, having a normal engine ecu your eclipse ecu checked at a local garage or dealership as part of a tune-up or diagnostic checkup can tell you a lot about your eclipse ecm  health. Or, if your Eclipse fails a state required emissions check, knowing the causes of high HC and CO emissions can help you determine the repairs needed. High HC emissions often indicate an ignition problem such as a misfiring or fouled spark plug, a cracked distributor cap, or bad plug wire. Anything that interferes with good ignition will permit unburned fuel to pass through the eclipse ecu and into the exhaust.

Badly worn piston rings and  valve guides that allow your engine ecu to burn oil will also cause high HC readings. Carburetor flooding.  or an excessively rich fuel mixture likewise can contribute to high HC levels. Loss of compression due to a leaky valve or blown head gasket can pass unburned fuel into the exhaust, too. Carbon monoxide indicates incomplete combustion resulting from too much fuel and or not enough air. Things to check for here include a clogged air filter, sticking choke, misadjusted
carburetor, plugged or inoperative PCV system, or a problem in the air pump or air injection system. Overadvanced ignition ecu timing can also send eclipse co levels soaring.

ENGINE COMPUTER ECU MODULE?? would it fit?

I have a 2000 Crown Vic LX non police car. Happens to be that the ECU went bad on my car and it's sending the wrong signals to the transmission. I was wondering, would a crown vic police car ECU fit on my car? I do have to understand that there will be some what more power if changing to a police ecu.

Will it fit, physically? Sure. All EECV ECU's look the same on the outside. But will it work properly? That's pretty doubtful.

"There are a lot of lines of code in the programming, and the instructions include calibration information designed for a specific vehicle application. So unlike Windows XP or some other piece of software you might purchase for your personal computer, the programming for a PCM is unique to that vehicle and that vehicle only.

The programming will vary depending on the year, make and model of the vehicle, the size of the engine, whether it has California, federal or Canadian emissions calibration, the type of transmission, gear ratios and tire size, and whether it has special options (such as traction control, automatic climate control, etc.) that interact or communicate with the PCM.

No Swapping!
Because of this, you can’t simply swap a PCM from one vehicle into another and expect it to work perfectly. The swapped PCM may allow the engine to start and run, but it may also cause weird driveability or emission problems, or various fault codes to set."
