A Guide to Buying the Best ECM, TCM & ECU for Your Car

23 Oct

Nowadays, most modern cars normally come with ECUs, or engine control units.  The engine control units are computers that control some functions to ensure that your car is performing at optimum levels.  Also known as powertrain control modules, these computers are hardwired into many different parts of a car so as to monitor and manage aspects such as emissions, fuel economy, and a range of other functions.  In addition to this, ECUs gather information from the sensors which are located in various parts.  This data is then analyzed and the suitable action taken in accordance.
If you are considering buying an ECU for your car, it is important to learn about the options available for you.  You may decide to buy a new unit for the car by visiting a spare part dealer who sells new parts.  Also, you can decide to purchase second-hand ECU, by approaching your local car repair shops to look for a used, compatible engine control unit.  On the other hand, you can shop for the unit online through websites such as eBay.  Online shopping is particularly better since you will get various alternatives from several traders.

Before buying the engine control unit from any store, it is important that you do your due diligence.  You should be educated on how the units work so that you may differentiate between a high-quality unit and an inferior one.  It is also wise to establish whether your car really needs a new part in the first place.  Sometimes, your car can function optimally with an ECU remapping instead.  Therefore, it is advisable to seek professional help to determine whether your car needs a new part.

These days, modern cars are usually bought with inbuilt ECUs.   These engine control units are designed to function in driving conditions as foreseen by the manufacturers.  In the majority of these cases, the cars are driven by typical drivers.  Thus, when modifications are made to the car, they will send the manufacturer-supplied ECU to a shock, causing it to malfunction or fail to function altogether.  You will then need to buy a new unit if that one cannot be reprogrammed.  It is, therefore, necessary to ask such questions before you buy a new unit.

It is also good to know if your car can function with an ECU remapping.  If your car has a programmable ECU, then you may choose to remap it rather than buying a new ECU.  However, remapping needs access to some software and associated know-how, although it is not hard to fix.
