FI GSX-R an TL TRE Mod.....from Gixxer.com
Those of you with Fuel Injected GSX-R's and TL's, heres a quick and cheap mod for your bike. Myself, Canadian Gixxer and Jim did ours today and the difference is quite noticable. Heres what this mod does....
As per the original post @ Gixxer.com...
When you are in 1st, 2nd, or 3rd gears, the computer figures out how much fuel to inject as usual, but, to limit torque, it backs off this amount and / or closes the secondary throttles a bit to limit your power. This is to keep torque down when you are in the lower gears. I guess it's to keep you from zipping around on the streets or whatever. It doesn't do this in the higher gears, because if you're in 4th gear or higher at low RPM's and nail it, you don't have much torque anyway.
The gear position sensor is a variable resistor. When in 1st gear it's like 500 ohms. When in 6th gear, it's about 15,000 ohms. So, if you clip the wires going to the ECU, and hook up a 15K ohm resistor, the ECU *THINKS* you are really in 6th gear all the time because it is sensing 15K ohm (6th gear) of your resistor rather than what the GPS is actually reading. So, when you roll on the gas, it puts out the full amount of power the engine is capable of
