The right EFI kit can make a big difference when it comes to performance at the track. Modern performance EFI systems have more options to put you in control of your vehicle’s power output than ever before. That’s why many drivers are upgrading, not just from carburetors and OEM systems, but from older performance fuel injection kits to newer designs.
1. Control Over Your Power Profile
Fuel injection systems are designed to learn from the environment and your engine’s behavior to optimize the results you get from your engine. When you upgrade to a performance EFI, you gain the ability to fine tune the way the ECU handles those changes by tweaking the timing and other features to optimize for overall power output, throttle response, or other situationally-specific needs.
That gives you an edge when switching between competition events by giving you the chance to load out profiles tuned to each one. Coupled with the right tools and a rooftop cargo carrier hard shell for your street vehicle to keep them nearby, it lets you make big changes on site when your situation pivots.
2. Data Logging for Better Fine Tuning
When you have the numbers on your vehicle’s performance over time, you can dial in your ECU profile even better. This is especially helpful when you make big changes to your engine like the installation of a supercharger kit, because it can show you where to adapt your existing profiles to make the best possible use of your new upgrades.
That’s an advantage that keeps paying off as you keep replacing or upgrading parts. It’s not just an advantage when you’re going up a performance level, either. Refreshing spark plugs or other cyclically replaced parts can change your performance enough to make a look at the numbers worth your time, just to be sure. Chances are you tuned things over time as parts aged, right?
3. Improved Mixture Distribution
It’s not just a matter of having the right fuel/air mixture to optimize the reaction every time your engine fires. A state-of-the-art EFI system also normalizes the distribution of the mixture across all cylinders, leading to a more even power output across the entire engine. The more sophisticated your EFI system, the more powerful its ECU and software gets, the better it is able to do this. A better distribution of work across the entire engine helps maximize its life, too.
4. Better Power and Torque
When you make the change from carburetion to injection with an EFI conversion kit, you make noticeable gains in power output because you’re feeding the engine more precisely. Upgrading your fuel injection kit to a more sophisticated and powerful system builds on those improvements, delivering you further gains and helping to make sure you get the most out of the rest of your racing upgrades.
If you have recently made some changes that should improve your power out more than they have, it might be time to improve your fuel system again. At the very least, it’s worth checking out this year’s models to see if the changes are big enough to put it into your long-term upgrade plans.
