An LS engine is a great way to modernize a vehicle and take advantage of the attributes the engine has to offer. If you’re going to stick with EFI for the LS engine you can use the stock ECU, however, an aftermarket system will give you more control. The FAST XFI Sportsman Fuel Injection kit for GM LS Applications brings more tuning options and power management to your fingertips.

An OEM ECU will control an LS engine for a high-performance swap application, and it will cost less than an aftermarket unit, but, it won’t be as robust as an aftermarket ECU like the XFI Sportsman system. The extra level of control the XFI Sportsman system offers will provide precise control of fueling, spark, air/fuel targets, and much more. CAN network support is part of the XFI Sportsman’s functionality, so it will support different devices via a CAN network wire.

The EZ-LS Ignition Control that comes with the FAST XFI Sportsman Fuel Injection kit for GM LS applications will cover all the spark duties for your engine. Another advantage of the FAST XFI Sportsman system for LS engines is the fact it allows for real-time tuning, which means you don’t have to constantly reflash the ECU as you do for an OEM system. The FAST XFI system also comes with the Alpha-N strategy to help drag racers be more consistent at the track.
