The TRE is a device
which allows much better throttle response in the first 4 gears on
EFI sportbikes. What the motorcycle manufacturers have done is
to make a separate ignition map for each gear. This has been
done for either safety and/or emissions reasons. However, it
limits the power and smoothness of your bike in the first 1/2 turn
of the throttle in gears 1 through 4. The motorcycle
manufacturers were clever in the design of the stock timing retard:
It still allows full timing at full throttle. As you shift up
through the gears, the amount of throttle needed to access the
advance curve decreases, until you make it into 5th gear and then
it's gone - you have nice, smooth operation. The TRE makes
your motorcycle respond just as smoothly in the lower gears.
Quick facts
about the TRE
-
A direct "plug
in" installation - no cutting or splicing.
-
Has no effect at
full throttle (except ZX-14).
-
Does have an
effect from closed throttle up to half throttle in gears 1
through 4 at ANY rpm.
-
Disables the
speed limiter on the 2001 through 2006 GSXR1000 and 2001 through
2006 GSX1300R. This is because the ECM does not see
the 6th gear ignition map, which has an earlier rev-limiter.
-
DOES NOT affect
full throttle horsepower (except ZX-14). This has been
verified on the dyno as well as on the road under controlled
conditions.
-
For "race use
only"
-
Does not comply
with your warranty.
-
Does not comply
with federal emission and/or safety laws.
-
Will not allow
your speedometer to read higher than the black box will allow it
to.
