One of the best VTEC and air flow controllers just got better. A'PEXi took the functions of its SAFC and VAFC and combined it into a single, easy-to-use tune controller with a bright color screen. There are 16 points of fuel correction, air map settings and control adjustments for VTEC, based off engine RPM and load. Even if you don't rock a Honda, you can still use the AFC Neo as it can also protect your car from stalling out, particularly if you're running hotwire sensors or open-air blow-off valves. Another cool feature is the flash memory status, which retains any data settings if the battery is disconnected.
