Product Description
The Kawasaki Ninja 1000SX is a great machine, but the factory ECU programming leaves plenty of room for improvement. Soft throttle response, restricted midrange power, and throttle blades that close down at high RPM keep this bike from performing to our standards. You twist the throttle asking for more, but the ECU has other plans.
Schnitz Racing ECU reflashing addresses these restrictions to deliver sharper throttle response, stronger midrange acceleration, and a harder pull through the upper RPM range. We revise the electronic throttle maps so the blades open more aggressively and stay open when you’re asking for full power. Revised ignition timing improves low-end and top-end performance, while removing the top-speed restriction lets you take advantage of what the engine has to offer.
You paid for the full speedo—so let’s use it!

What is ECU Reflashing? ECU stands for "Engine Control Unit." It is the computer that takes information from the various sensors on the engine like crankshaft RPM, manifold pressure and throttle position to determine how much fuel to deliver through the fuel injectors and when to fire the ignition coils. The computer "chip" that is the heart of the ECU is usually an EEPROM -- an Electronically Erasable Programmable Read Only Memory chip. The Read Only part of that means the chip retains its programming without periodic electronic refreshing; loss of electrical power doesn't lead to the chip losing its programming (It's like the CMOS BIOS of a computer). "Flashing" the chip involves electronically erasing the read only program and replacing it with new, updated information (the engine control 'map').
