Ok, I know I have read about this on this board, but I can't find the thread. Anyway, does the TRE work as advertised on the 2002 model? If not, is their another alternative to unrestriciting the 02. Im more interested in the smoother power delivery as advertised on the Hayabuszone website than top end.
I have the TRE on my '02. Big difference in throttle response in low gears,
Idles a bit rough, I like that... sounds like a big-block with a high lift cam...
But I don't know if it derestricts. From what I have read, it does not because the '02 ecu restricts 5th gear also, which is what the TRE makes it think it is in 5th gear. To me, no biggie as I don't plan on going that fast.
I do, however like to go fast in a hurry. Just got my 16tooth sprocket today. Gonna slam that puppy on before dark, I hope. If I can ever get out of work!
GOSH!!!!!! I know 194 is nothing but it really is..it's not 200
............................................sumthi'n about a number..
imagine going 100 mph over 100 mph..kinda magical !YEA!
N.E. Let us know when you got there..
Oh btw..way narisccus.[sic]..wrote an article how to make a switchable tre, which i did..sitting at a stoplight..flip the switch= equals smooth idle..yea...resistor and switch..a little soldering..some wire and shrink tubing ..all is well....buy at radio shack..20 dollars..or so.
the mph speed is not the concern of the restriction. It is the rpm's. 10500 is the restricion by the ecu. the 2002 model restricts rpm's in 5th and 6th gears. the 2001 only restricts 6th gear. The TRE tricks the ecu into thinking it is in 5th gear. Thus, works fine on the 2001, but not on the 2002.
quote from ivansperformanceproducts.com - "The TRE will disable the speed limiter on the 2001 GSXR1000 and 2001 GSX1300R. This due to the fact that the ECM does not see the 6th gear ignition map, which has an earlier rev-limiter."
If someone's special TRE eliminates the rev-limiter on an '02 busa, then it does not create the 5th gear resistance. It is telling the ecu it is in 4th. If that is the case, then I apologize for my mistake. 99% of TRE's out there read 5th gear resistance. Any TRE that eliminates the 2002 is not using the 6th or 5th gear resistance.
Do your own research, I have done mine. You seem to have all the answers and consequently won't believe anything you read here.
Contact Ivan ( I have, again, 5 minutes ago) and ask him the question yourself. He said he needs to update the web page.

You may also be incorrect about how the ECU limits function.
The 99-00 ECU retarded the timing in all gears but 5th-6th. The TRE for those years makes the ECU think it is in 6th gear, hence removing the timing retard. (99-00 TRE uses a 6th gear resistor for all gears) Those years the ECU had no restriction on RPM in 6th.
The 01-02 ECU restricts the RPM in 6th gear so it consequently restricts to top speed. The TRE makes the ECU think it is in 5th gear so the RPM can go above 10,500. (00-01 TRE uses 5th gear resistor). I also believe the maps in the 02 are slightly different.
In the early Busa years (99-00) the riders in the UK discovered that better performance could be had by using the 5th gear resistor and were using that instead of the 6th gear resistor from day one. I took their word for it as I haven't tried it.
This topic has been beat to death on LaBusas and SH.org. Go to either site and do searches on "TRE 02" or better yet call Ivan. Like I said, his response (which I read) addressing this issue on sh.org was lost.
If you won't take my word for any of this, just call Ivan. That's what I do when I disagree about some issue. Just go straight to the well. In this case Ivan, the inventor.
To everyone else yes Ivan's TRE works on the 02 Busa.
