TRE/ EFI Mods

Who has experience with a TRE? I'm wondering who makes the best ones for performance gains, and does it really create a noticeable difference in throttle response? Also, anyone had problems with their Gixxer's EFI system after installing PC and an aftermarket Exhaust? I may just need to clean my ****, but who knows? I've talked to other Gixxer owners and they have had the same problems with starting up their bikes after the mileage racks up, especially in cold weather.

TRE won't do anything for performance as it is a mod used to make the bike more street friendly. In most cases it allows normal timing to be used in gears 1-4 below half throttle. They normally don't put any kind of timing retard above half throttle. I know it use to eliminate some kind of governor on the Busa, but I don't think that is true for the gixxers.

I know you can fix the cold weather start problem by getting an aTRE that turns itself off in neutral and fixes any issues you have with cold start by starting it in neutral. I designed one myself for the SV.

So by starting my bike in neutral with an aTRE on it it will reduce the effects of cold start? Not tracking, could you explain in further detail? Maybe draw a picture those work great for me. haha.

An aTRE is an automatic TRE. It is designed to turn itself off electronically when you put the bike in neutral so cold starting with a TRE isn't an issue because the TRE is off.

How a TRE works is it tricks the computer into thinking it is in a certain gear all the time. With the SV TRE, you made the computer think it was in 5th gear all the time by feeding the computer a certain resistance for the gear you want. When you open circuit this connection, it thought it was in neutral. So I used a transistor and the voltage feeding the neutral light to act as an electronic switch, so when the neutral light came on, the switch opened causing the open circuit desired.

I really don't see why you would need a TRE on a 600. On my liter, the biggest issue was throttle response. Teh TRE helped that.

As for you EFI issues, you must have something f'd up with the PC and exhaust

It's not, it wasn't helpful on the SV either. That thing felt like an on/off switch regardless of what you did to it.

It really depends on what you want to do with it. The SV is a great all around bike, it's got a lot of get up and go but not much throttle control. It really doesn't build like a 600 does. You should know that feeling of precise throttle control from your zx. The SV on the other hand is boom, it's there and that's all the pop it is going to give you. It's still a very very fun bike. I am sure PC would love it.
