Bottom line. The TRE will do nothing for you that you couldn't do before just by twisting the throttle. The only noticable change will be that it drasticly lessens the engine braking.
There is a definite improvement when rolling on the throttle. It feels ALOT more responsive for the reasons you explained. If you roll on the throttle in 2nd gear, up to half throttle feels like a dog compared to having a TRE. Just my opinion.

Re: What is a TRE

I purchased the X-TRE from HealTechElectronics. I have a GSX-R 1000 ,2005. It works as they claim. If someone is telling you it's not worth it? They just don't know. It maintains your stock gear position indicator. And the throttle response is very good. For a simple 129.00, it will be worth it. Yeah, you get to cut 1 wire. Make sure it's the correct one. No extra gear position indicator, needed. I think some dudes just aren't fellin' it. It's that riding thing again.

This was already clearly stated. For those of you who like to wheelie it is a great mod. If you are a track rider, then it depends on your riding style. 600's are geared for 3rd into the corners. So it helps throttle reponse regardless. And if you ride the front brake (trailbrake) deep into the turns then it is well worth it. Argument over, buy one and you be the judge.

Just google healtech GiPro A TRE. It is well worth it IMO. For any CC sportbike.
+1000 bro !!! i also have this mod. and agree wit u, very worthwhile for the $$

If I understand it correctly you can just circumnavigate the TRE limitation by twisting more throttle if you want?

It's effect is like the linearity of the throttle setting in racing games? If that makes sense? I.e. 0-25% twist is 0-15% throttle opening, 50% twist is 35% opening, 80% twist is 70% opening, 90% twist is 85% opening and 100% twist is 100% opening? I.e. it makes throttle control easy for you?

If I understood it correctly I'll keep it. I have trouble being smooth on the throttle as it is on the 750.

Re: What is a TRE

No, it won't help you with drag racing at all. You have no time at low rpm and a small throttle opening when you're drag racing. I'll tell you one place it sure does help though.

Riding on a wet track. It helps a whole bunch to have smooth throttle response at smaller throttle openings when you are riding track in the rain. There is plenty of time spent just feathering the throttle, and any jerkiness on your part, or the bike's part, will take you down.

I just spent a weekend doing just that. Some semi-dry sessions, but more wet ones. I'm glad I had this mod. You can't just be smoother on the throttle to make up for a jerky throttle response in those conditions. People were dropping like flies as it was, regardless of what brand or model of bike they were on.

Re: What is a TRE

I uploaded these for another thread but I might as well post them here...

(These are for K6/K7 US GSXR-750 (32920-02h10)

Ignition Map (Group 1/2) used in 1st - 4th gear.




Ignition Map (Group 3) used in 5th and 6th gear (all gears with a TRE).





Compare Map ( Group 3 minus Group 1)

Again I'd like to thank you for sharing,so there is not really much gain to use a TRE on the 750...

Re: What is a TRE

so the spot in the comparison group is the spot that the timing is retarded by the 1-4 gear ignition maps. And when we can flash the ECU, those spots will be adjustable with a computer anyway, right??
