With a modern car, it’s really the electronic controls that modulate the fuel and throttle settings that you used to adjust with a screwdriver. There are plenty of things to dislike about the dependence on your chip, but you’ve got to admit, it provides a whole different level of performance control at your fingertips, with curves you can optimize for maximum efficiency, power, and fuel economy. Apexi is a company that’s been making controllers for these systems for about as long as aftermarket programmers have been around, so you’ll want to go with a genuine Apexi Power Programmer for its advanced features and the convenient design that comes from years of experience and feedback. A great big first step into this world of control is their SAFC Neo, which gives you 16 user modifiable fuel system and throttle settings, so you can enormous power boosts from your engine. You can also use this Apexi Power Programmer to monitor all your crucial systems, so you can find out just how hard you dare to push your vehicle without endangering your engine. The SAFC II is a step up toward competitive levels of control, and the VAFC II is optimized for VTec systems.
