Schnitz ECU Reflash Suzuki GSXR1000/R (17-24)

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').

What is the PAIR Valve? The PAIR valve is a solenoid that opens to allow fresh air to enter into the exhaust system to aid in burning hydrocarbons to reduce emissions.  There is no performance gain from removing the PAIR valve.  The only possible benefit is reduced deceleration backfire or popping. If this is removed, a code will be tripped and the dash FI light will turn on.  We can disable this in the ECU for a small fee.

What is the Exhaust Valve Servo Motor? The exhaust valve is a butterfly valve in the OEM exhaust system that is used to lower exhaust noise.  Many aftermarket exhausts eliminate this valve.  If a delete device is not installed, a code will be tripped and the dash FI light will turn on.  We can disable this in the ECU for a small fee.
