More than 1.5 years of research and development has been invested into my Z900RS ECU project !!

This includes reverse engineering all the stock North American Z900RS ECUs for this bike, purchase the most popular exhausts,
dyno test and tune them on my own personal Z900RS, and on the road testing.

My exclusive software & tuning experience offers you the best result possible.
(because my software can access the entire file, and commercially available software does not)

This offers you the most refined feeling, smoothest, most powerful, best driveability, best fuel economy
than you will find in any other ECU flash offering for your Kawasaki Z900RS.

My Kawasaki Z900RS ECU programming (Re-Flash) includes the following:


1) Fix all fueling problems inside the ECU.
(The ones that cannot be fixed with an external fuel tuner or other commercially available methods)
a) All gear dependent maps equalized
b) Main fuel tables (A/n) - adjusted specifically for your exhaust at all active throttle positions.
c) Vacuum tables (MAP)- adjusted specifically for your exhaust in all active areas.
d) Emissions compliant sub-routines that affect driveability - turned off.
e) All response delay filters (detuning items) - turned off.
f) Deceleration tables thoroughly tested and re-adjusted for best closed to part throttle response.
g) O2 sensor disabled - No need to unplug, or can be removed if desired.
h) Lower cold start fast idle to under 2500 rpm (varies slightly from bike to bike)

Includes fueling changes specific to your exhaust !!
External fuel tuner not needed - just plug in and go !!


2) Disable fuel cut - ie; Jerky throttle

Don't know what "fuel cut" is? - CLICK HERE

a) Engine stays running when the throttle is closed.
(with stock ECU programming, the injectors are not running when you decel)

b) Gets rid of poor, imprecise throttle transitions from closed throttle.

c) Eliminates feeling of driveline lash and jerky, delayed throttle response.

d) Changing gears is dramatically improved.
Without fuel cut disabled, "neutral throttle" is not possible.
This is the direct cause of your touchy, jerky throttle because the engine isn't running during decel.

e) Dramatic improvement upon re-application from closed throttle (in all riding conditions).
(Throttle re-application response feels like our old carbureted bikes used to feel)

f) No need for a different throttle tube ratio to try to prevent jerky response.
(which it cannot do anyway)

g) Gets rid of annoying popping and banging during decel and when re-applying the throttle from closed.

3) Close AIS valves electronically

No need for block-off plates for air injection system
No popping on decel !!
No hoses to plug - Just plug in your ECU and go !!

4) Cooling Fan comes on at 195 degrees and goes off at 186
Helps keep engine cooler when you are stuck in traffic.

5) Reprogram Sub-throttles for best response and to remove power restrictions

a) Allows all of the 900 engine's available power - whenever you ask for it.
    All power restrictions are removed.

b) Gives immediate engine response to the throttle with no restrictions.

c) Low rpm power is improved, while preserving fuel economy.

d) Response delay filters turned off - part of original detuning.

e) Engine responds and feels immediate, light and rev-happy

7) Complete custom re-curve of ignition timing

a) Set main timing tables for maximium power and driveability across the entire rpm range and all throttle positions.
This also helps provide better fuel economy, and less vibration when cruising and moderate acceleration.

b) All gear dependent maps equalized and adjusted for best power and fuel economy.
Adjust timing to be the same for all gears.

c) All emissions compliant /detuning sub-routines turned off.

d) Gets rid of part throttle timing retarder for more response and less vibration when cruising and moderate acceleration.

e) Gets rid of ignition timing issues that are unique to the Z900RS.

8) Lower cold start fast idle to less than 2500 rpm (varies slightly from bike to bike)

9) Reduced running temperatures

10) All driveability inhibitors removed.

11) Free updates when/if we make improvements.
(shipping not included)

12) Free updates if you change your exhaust.
(shipping not included)

13) Return your ecu back to stock at no charge for any reason.
(shipping not included)

14) Anything that compromises performance and/or driveability is eliminated.

Includes fueling changes specific to your exhaust
External fuel tuner not needed - just plug in and go !!


All testing and tuning was done in house on both of my personal Z900RS & Z900RS Cafe shown above !!

Dyno tuning not necessary !!

We can reprogram for USA, Canada, Europe!!

We no longer offer this service for Australia & New Zealand

European customers for this model must contact our European partner here:

Dyno tests

ALL TESTS ARE SHOWN IN 5th GEAR




All stock vs. final result - a truly massive gain !!

Kawasaki really neutered this bike in many areas.
