The injectors running at higher pressures, generate more heat inside the cylinder and can burn holes in the pistons. These systems have been known to be hazardous. These gains don’t always come cheap though.
With the added increase of fuel, the engine will have modest gains of 10-20% more. More pressure equals more fuel being forced through the injectors and into the cylinder. Diesel performance chipsĪ diesel chip is a simple device that joins into the common rail pressure circuit and ramps up the fuel pressure inside of the common rail. Let’s look at two of the most common options available in today’s market – Diesel Performance Chips & ECU remapping. Improving today’s diesel engine performance To increase today’s 4×4 diesel engine, you have to get technical – it’s all about the computer control unit. This means that bolting on parts to push your vehicle to new limits is no longer enough. Thanks to the introduction of the common rail diesel system, the engine’s combustion is now regulated by computer control units known as ECU’s. Performance upgrades in today’s Diesel 4WD market are the result of technological advancement. But don’t forget that on top of that small fortune, you’re most likely going to have to upgrade the rest of the engines combustion system to get it working at top capacity. These performance upgrades are all well and good if you’re willing to spend a small fortune. The goal of these modifications was to cram more of the good stuff into the chamber – which resulted in a bigger bang. Performance upgrades focused on fitting bigger turbos, bigger injectors and also highly modified injector pumps. It’s no wonder so many are seeking performance upgrades! So, what’s changed?Įarlier model diesel 4WD’s ran mechanical injector pumps. Then, when it comes to overtaking or climbing hills, well… just forget it. We’ve all been there… you’ve added another set of wheels to tow along behind you and the extra load capacity is sapping your vehicle’s performance. You feel like you’re barely chugging along at the speed of smell.Ģ. The standard engine package doesn’t quite cut the mustard. There are a number of reasons you and other Australian 4WD owners are switching to performance products but really it comes down to these two ġ. Why upgrade your vehicles diesel performance? This article will take the guesswork out of choosing a system that performs the best, doesn’t break the bank and most importantly won’t risk the lifespan of your engine. Have you ever found yourself confused by the number of technological gizmos on the market claiming to enhance the performance of your modern Diesel engine? – Rest assured you’re not alone.
