Ivan's TRE (Timing Retard Eliminator ) is available from the
part is a simple plug in that vastly improves drivability in
the lower gears and on the later top speed restricted models,
the TRE removes the restriction.
How does it
work? Your bikes ECU (computer) changes the ignition advance
depending on what gear you are in. The best advance for all around
drivability is the one in 5th gear. The TRE tricks the ECU into
thinking it is in 5th gear all the time. Same for the speed restrictor.
The computer kicks in a rev limiter in 6th gear to restrict top
speed. Again, with the TRE, the computer never knows it is in
What do users
say about the TRE
cow..No wonder Suzuki's legal department made them retard the
timing in 1st and second.
It has smoothed
out the on/off throttle whack by about 50% for me.But, what shouldn't
have surprised me and did, is the power delivery's improved.
And it's so smooth that you're at redline before you have a clue.
I'm gonna have to allow a bigger budget for rear tires. Another
user mentioned having to adjust the suspension to allow for the
greater power delivery, which I thought was a bit of hyperbole,
but he was correct."
The TRE does
not increase horsepower as measured on a dyno. The TRE may violate
federal emission controls, and is for "off road" use
