Schnitz ECU Reflash Suzuki GSXR750 (11-24)

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').

How can you offer this at such a low price?  We have been tuning sport bikes for 15 years.  Our business is offering performance products for motorcycles.  If an ECU is programmed to limit power output of that engine, then our products performance will not meet your expectations.  We want to ensure you get all you can out of your purchase from us. Pulling the ECU data is no longer a “black science” limited to just a handful of computer wizards that have an exclusive on this technology and expect you to pay 3 or 4 times our price.  We’ve been doing this since 2006 on Suzuki sportbikes that were limited.  Now we have expanded to various other models.

How does your service differ from others – Our reflashing services remove restrictions that the OEM's have programmed to meet government regulations and that reduce throttle response and power output for novice riders.  You are not purchasing a “lifetime” flashing subscription for services you won’t use.  Our a la carte style checkout system allows you to purchase only the options you need.  While we do offer fuel adjustments to match aftermarkets exhaust systems, we believe that you should have control over fuel adjustments with units such as Power Commanders that can be adjusted to match your specific needs.

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.
