When using RexXer products,
the Vehicle Type Approval will expire
and thereby the insurance cover.
It s no longer permitted to use the
vehicle on public roads!
IMPORTANT: The RexXer EVO User
is married to the VIN number of the ECU.
Thereby it s possible that the RexXer
EVO User has still access to the ECU
after an update via Workshop tester
or another RexXer device.
You can flash again your tuning mapping
into the ECU.
Yet we recommend to flash back the
original mapping in advance before each
When using a mapping with lambda
controll switched off, we recommend
to diconnect the lambda plugs
permanently "after" the flash!
incl. license and suitable tuning-map!
incl. serial interface cable ZU-RV08E!Optimum driveability?
An important factor for a good running engine is the air-fuel Ratio (AFR),
the measurable ratio of air to fuel, which is present during combustion.
If the AFR is not optimised the bike can exhibit certain problems e.g. by
an excessively lean ratio, which often causes annoying constant velocity
shocks, delayed throttle response and performance holes in the power
curve. A too enriched ratio, besides poor performance leads to high fuel
consumption. The main reasons for these issues are poor set-up at the
factory, changes tothe intake or exhaust system. Currently the most
common method for adjusting the fuelling map of a bike is the installation
of an auxiliary module which is complex and full of compromises or the
replacement of the standard engine control unit (ECU), which is costly
and often not adjustable racing units. With the RexXer EVO
, these measures
are a thing of the past! The RexXer EVO
allows first to replace the standard
tuning map of your ECU against another in only 3 easy steps without a
residual auxiliary module. Thanks to the RexXer EVO
, the programmer for your
series ECU, your standard setup can be changed to a moderate improvement by using free tuning
maps of different matching states.
Now the stock mapping and the modified tuning mapping are fix in the device memory and you
can change between the maps as often as you want!
Whatever modifications you have made, if only the attachment of a performance-enhancing exhaust system, a sports air filter,
the use of optimized camshaft or pistons with higher compression etc - to exploit the gain in power fully,
the engine management has to be adjusted with the appropriate changes! This is accomplished by using a tuning map.
This is a specific dataset which is modified to the model and the features controls e.g. the injection,
spark advance and many more important maps of the ECU.
Attention: The RexXer EVO "User" only allows the programming (flash) one vehicle and will be married with it s ECU.
You will get the RexXer EVO "User" with your requested tuning map.
At purchase, you will get a fitting tuning mapping for your bike for fee! If you need another,
additional (fee-based) tuning map later, you can you can order it any time with us.
You will then get it by E-Mail and the tuning map can be transferred via USB cable from your computer
to your RexXer EVO "User".
After that, you connect the device with your bike and reprogram it very easily.
Ordering Note: When ordering, please specify the following notes under Step 3 in the
vehicle brand, vehicle model, exhaust system (stock or after-market; brand), air filter
(stock or after-market; brand), header (stock or after-market; brand),
disable Exhaust Valve?, disable O² Sensor?
The more accurately you provide the information, the better we can choose a suitable mapping for
