Want your VN1700 to feel like it has real throttle cables?
More than 1 year of R&D has been spent on this project !!

Driveability and tuning issues cannot be completely solved with an external fuel tuner,
This is the best result in driveability and power possible anywhere for this model - our proprietary software guarantees it.




My Kawasaki VN1700 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 99% of setups - just plug in and go !!


2) Disable fuel cut - ie; Jerky throttle
Don't know what "fuel cut" is? - CLICK HERE

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 riding conditions).


3) Close AIS valve electronically
No need for block-off plates for air injection system.

4) Cooling Fan comes on at 195 degrees and goes off at 188

5) Re-program Kawasaki ETV (Electronic Throttle Valve) for linear throttle opening and remove power restrictions
(Responds and feels just like a cable throttle)

a) This allows a more sensitive throttle that is easy to control.
If you ask for 10% throttle opening, you get 10% throttle opening

b) Works well with stock or aftermarket throttle tubes

c) Allows full 100% throttle opening whenever you open the throttle, just like a cable throttle.


6 ) 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 VN1700'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.

7) Reduced heavy engine braking on decel.
More relaxed gear changes and throttle modulation at all speeds.

8) Reduced running temperatures.

9) All power limiters removed

10) All driveability inhibitors removed

11) Free upgrades when/if we make improvements. (shipping not included)
**UPDATED 9-2017 - Engraving will read "C4B" on the back of your ECU**

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

13) Anything that compromises performance and/or driveability is eliminated.
---- External fuel tuner not needed for most (99%) setups !!

All testing was done in house on the above VN1700's

Intake tests

All aftermarket intake systems will lose 1 or 2 hp below 2500 rpm compared to the stock intake system.
This is due to shorter velocity stacks.

With more than 100 ft/lb of torque available at 1500 rpm, you can't feel it.










A massive gain over stock !!
