The engine control module (ECM)  is one of the most important components of your highway truck. From calculating optimal fuel-to-air ratio to tuning engine spark, it’s responsible for controlling all of the engine management functions.  When the ECM has any problem, it can cause all sorts of issues with your highway truck. In this article, we’ll have a look at the five telltale signs of a bad ECM and how to perform a diagnosis. Let’s get started! Truck won’t start If your truck doesn’t start or take hiccups during startup, the chances are that something’s wrong with your engine. While the problem can range from a clogged fuel filter  to defective ignition switch , but once you rule out these possibilities, the ECM likely requires repair or programming.   Stutter in engine An engine stutter is caused due to fatty fuel-to-air ratio, which can again indicate a problem in ECM. The science behind this problem is fairly simple. The mass airflow sensor re...

To ensure that your engine control module is functioning at optimal levels, it’s essential to perform routine checks and maintenance.  By scheduling regular examinations, you’ll reduce the number of repairs that your vehicle will need in the future. You’ll also be optimizing performance, and extending its service life.    The ECM is the brain of your vehicle. It is a critical component of all modern vehicles, determining efficiency and performance characteristics, and coordinating various integral systems.  The sensors in the engine carry information from various parts of the vehicle to the ECM and back.  Through this information and subsequent calculations, the engine is tuned for maximum fuel efficiency and power.  So for your vehicle to work at optimal levels, you need to take care of the ECM. The following are some crucial maintenance tips: Engine Maintenance Engine oil is your vehicle’s lifeblood. For most vehicle owners, ...

In a post- Volkswagen scandal  world, most people know that their vehicle’s computer can be reprogrammed; this programming determines how several fundamental aspects of your vehicle perform. It also determines whether emissions are within legal boundaries, among other variables. The automakers at Volkswagen played around with software to make it through emission tests with higher-than-allowed emission rates. But here’s the question vehicle owners are asking in the aftermath: if tweaking the system is possible, is it possible for vehicle owners to optimize ECMs for fuel efficiency?  It is. However, you might want to think twice before indulging in your mini-DIY (and probably illegal) project. Why Is It Risky To Hack Into My Vehicle’s ECM? ECMs for automobiles are getting increasingly complex each passing day. While vehicle enthusiasts fiddle with them all the time, irreparable mistakes occur way too often.  Why do people fiddle with them then? Some ve...
