What You Should Know About Your Jeep ECU

Automobile manufacturers consider a number of factors when they design electronic systems for their vehicles. In Jeeps, most manufacturers consider performance levels, dependability and emission levels. Though Jeeps are performance oriented vehicles, emission norms and the dependability of the engines normally override it during the manufacture. So what happens is that the engine performance on the road is much lower than what it is supposed to be.

To enhance the performance levels, two things can be done: the Jeep ECU (engine control unit) is tweaked by externally modifying the ECU, without altering the original mechanics of the engine or even replacing it with a specifically tuned ECU that will help improve performance.

Mostly, people get their Jeep ECU tuned when they need more power or higher fuel efficiency or even for better emission controls. Some decades ago, this was called chip tuning and it was very much in vogue.

The original ECU of your vehicle may be replaced with a custom-made ECU to handle the required functions. Alternately, a programmable ECU, which can be mapped to the engine, can also be wired in. These days, the ECU can also be tuned by software updates. Make sure that you get your replacement ECU from a reliable dealer, who will properly program and flash it to your vehicle.

The vehicles which have the modified ECU must use high quality fuel and have to be serviced more frequently. However, there is also another thing that Jeep owners, who want to get their vehicles tuned, need to be aware of; many of these software upgrades escape the attention of the vehicle manufacture. So the warranty on the engine holds despite the higher tuning that the vehicle has been modified with. In addition to this, many of the systems may not be as per norm on the regulatory or environmental fronts and could be treated as a violation, if there is a clamp down on it.

Some countries in the European Union have brought in a regulation where these aftermarket tuners must meet the requirements of a recognized authority or regulator. If vehicle owners don't meet these terms the vehicles operating permit may be revoked and will stay so, even after the software is taken out. The regulations further states that the insurance companies are informed about all upgrades for the ECU. This would, of course, mean that the vehicle owner will have to shell out a heftier premium for the modification on the car.

Not all Jeep owners go in for the tuning. Some of them need to replace the Jeep ECU. In most cases, the ECU will not need to be replaced often; it will have to be replaced just once during the life span of the Jeep. Sometimes the ECU gets damaged because of extreme climatic conditions; especially humidity and moisture. It may also get affected by vibration, an internal failure or if the memory crashes. There are a number of replacement dealers and you have to be careful that you select a high quality replacement ECU for your Jeep.

Things You Should Know About the Dodge ECM

Today only a small percentage of people are still surprised that their cars are equipped with computers. The majority of car owners and drivers know that cars have up to seven microprocessors in the vehicle. These microprocessors enhance performance, comfort, and safety and are environment friendly.

Let's take a look at what the Engine Control Module (ECM) does in your car. It controls the fuel injection, the ignition timing and everything else that makes the drive smooth. If the ECM starts malfunctioning, then its time you thought of a replacement.

It is not for nothing that the Federal Government has mandated that fuel injection systems and ignition, in motor vehicles, must be computer controlled. There are three reasons for this move. Safety is the primary reason, followed closely by fuel efficiency and finally to bring down emissions.

In a number of cases, mechanics and owners have not been able to find out the real cause for problems in starting the cars. Take the case of my friend's Dodge ECM. He spend over $1000 on repairs and replacing parts before he realized that all that was required was that the ECM had to be replaced. So it is important that you identify the problem properly.

Parts such as the distributor, battery, ISC (idle speed control) motor, injectors, TPS (throttle position switch) and intake cam sensors are the ones which are often misdiagnosed as faulty. So if the mechanic does not realize that the fault is with ECM, you will end up paying a lot of money for parts you don't require.

When you are trying to locate a problem in the fuel injection systems you should take the informed approach to find out the error in the engine computer. In the case of the Dodge ECM, you should get it tested to see if it is functioning as per norm. What is required is an analog volt/ohmmeter. You need to place the testers on the top right and the bottom left pin for the ECM scan cable harness. If there is a total sweep from left to right then your Dodge ECM is functioning well. If the movement is only to the left, it means the ECM is not working.

You should get your Dodge ECM scanned by the authorized personnel who have the right tools for this function. Many of the manufacturers have tools for scanning the ECMs. The scan will throw up the errors. You can also check the ECM without the scan tools; for that you will have to refer to the manufacturer's manual.

The methods to monitor the malfunction indicator lamp (MIL) differ on certain vehicles. Some vehicles have an MIL built into the ECM while in some the check engine light will glow in series.
You will need to check the Dodge ECM if there is starting trouble. If the engine computer has packed up then you need to get a replacement. There are many online stores where you could pick up an ECM which is programmed for your vehicle.

There are also places where you could repair the Dodge ECM. These online stores are cheaper than the dealers. These remanufactured ECMs are ready for shipping so there is no waiting time.

Considering Buying A Car? Perhaps You Should Consider Buying A Former Rental

ByJennifer Calvin

Rental vehicles have to be reliable but of course, it simply makes sense that the only way a rental company is going to make money off these vehicles is by offering reliable vehicles. It is for that reason that most rental car companies don't hold onto their cars too long. Even if a car has been reliable and in good condition for the duration of the time they've been using it, most companies end up getting rid of these vehicles around 50,000-70,000 miles.

With the standard overall mileage of a modern vehicle being approximately 200,000 miles this leaves a lot of life left in those automobiles that a rental car company is going to be discarding and there are other reasons why these may be your most suitable option while shopping around for a used automobile. And some of them lie in the ways in which rental vehicles are babied.

Now a lot of people worry about the number of different drivers and the ways in which they may have beaten on a particular automobile but studies show that people tend to beat upon an unfamiliar vehicle a lot less frequently then they do on their own vehicle. For the most part this is because of the fact that they are more uncomfortable with a car that is not their own.

And in general rental car companies keep their vehicles well tuned and in service regularly. Because of the nature of the business and the need to offer secure and safe cars to renters most rental companies have a mechanic look most automobiles over weekly. Doing so helps to make sure that they are kept in the very best condition for as long as feasible. Of course the average vehicle owner does little by way of servicing their vehicle unless it's a required service or there is a problem.

If you are looking to pick up a dependable second hand vehicle you might not need to look any further than your local rental car agency. Most turn vehicles over on a pretty consistent basis and some will even get in touch with you when new cars become available. Knowing who owned your automobile and that they kept up on servicing it will help make sure you get many more miles out of that used vehicle. You'll likely pay a little more for a former rental vehicle than from one being sold privately by an individual however to obtain a reliable vehicle it is likely worth paying a bit more.
