am pleased to announce that I have successfully re-programmed the stock
Kawasaki VN900 ECU to my own exacting specifications as listed below.
Driveability and tuning issues cannot be completely solved with an external
This is the best result in driveability
and power possible anywhere for this model - our proprietary software
My Kawasaki VN900 ECU programming (Re-Flash) includes the following:
1) Fix all inherent fueling problems inside the ECU.
(the ones that cannot be fixed with an external fuel tuner.
Includes fueling changes - External fuel
tuner not needed for 95% of setups - just plug in and go !!
2) Disable fuel cut
a) Gets rid of poor throttle transitions from closed throttle.
b) Gets rid of annoying popping and banging during decel and also jerky
response when re-applying the throttle from closed.
c) Throttle modulation is noticeably improved over what can be achieved
with a fuel tuner alone.
d) Dramatic improvement upon re-application from closed throttle (in all
3) Remove AIS (PAIR valve) error code
can be removed without error code.
Cooling Fan comes on at 200 degrees and goes off at 188
won't heat up as much when you are in traffic.
5 ) Complete custom re-curve of ignition timing
a) Gets rid of part throttle timing retarder for more response and less
vibration when cruising and moderate acceleration.
b) Gets rid of ignition timing issues that are unique to the VN900's
c) Set timing for maximium power and driveability across the entire rpm
range & all throttle positions
d) Adjust timing to be the same for all gears.
Reduced heavy engine braking on decel.
relaxed gear changes and throttle modulation at all speeds.
7) Reduced running temperatures.
With the new tuning parameters, the engine produces
less heat which causes less wear on your engine.
8) All power limiters removed
More passing power when you want it and more fun
9) All driveability inhibitors removed
Throttle response is immediate and
the engine is extremely revhappy and always wants to accelerate.
10) Free upgrades when/if we make improvements.
11) Return your ecu back to stock at no charge for any reason.
(shipping not included)
12) Anything that compromises performance and/or driveability is eliminated.
External fuel tuner not needed for most (95%) setups !!
All testing was done in house on the above VN900
not necessary !!

All Stock VN900 ECU vs. Ivan's ECU programming
Tests shown here with stock intake and exhaust.
All stock VN900 vs. Cobra Powerport Duals and Ivan's ECU
Tests shown here are with stock intake.
The stock intake is pretty restrictive on this bike.....
As can be seen, the power really takes a dive after 5000 rpm with stock ECU programming.
The VN900 is definetly a restricted engine with stock programming.
Tests on this chart are with stock exhaust & stock ECU
With Ivan's ECU programming, the true potential of adding an intake system to
your Kawasaki VN900 can be seen here.
An impressive gain over stock !!
