Kelly Posted September 5, 2004 Report Share Posted September 5, 2004 Hi All, I just bought a GSXR that has a TRE switch. Could someone tell me what this does. The last bike I owned was 6 years ago, so I don't know all the computer setup on the newer bikes. Thanks for the help. Kelly Quote Link to comment Share on other sites More sharing options...
Bones Posted September 5, 2004 Report Share Posted September 5, 2004 My understanding is that the 'TRE' switch is a mod that tricks the gear position sensor that it is in 5th gear. The ECU uses a different map in 5th gear (better performance), and will increase low rpm throttle response. Also it will remove the 186mph restriction if your bike has it. Don't know of what the dis-advantages are; if any? Cheers Quote Link to comment Share on other sites More sharing options...
stuman Posted September 9, 2004 Report Share Posted September 9, 2004 TRE = Timing Retard Eliminator GSXRs retard the timing in the first 3 or 4 gears at low revs so you have less power. It's supposed to make the bike easyier to ride. The TRE fools the computer so it does not retard the timing and you get more power at low RPMs in the lower gears. On the Busa it also bypasses the top speed limiter that would normaly kick in at 186 MPH. Quote Link to comment Share on other sites More sharing options...
Kelly Posted September 11, 2004 Author Report Share Posted September 11, 2004 Will it hurt the engine if I leave it activated all the time. Basically it works like the older timing advance gears. Quote Link to comment Share on other sites More sharing options...
stuman Posted September 12, 2004 Report Share Posted September 12, 2004 No it won't hurt. Most people don't even use a switch. Quote Link to comment Share on other sites More sharing options...
