My ECU tuning philosophy can be found on this page: ECU PAGE

Testimonials can be found on THIS PAGE

My XVS1300 Stryker 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)

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 when re-applying the throttle from closed.
c) Throttle modulation is noticably improved over what can be achieved with a fuel tuner alone.
d) Throttle feels much smoother when re-applying from closed position.

3) Complete 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 high rpm timing retarder allowing the engine to make maximum power for longer.
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.

4) Raise rev-limit in all gears to 6600 rpm.
(some tests shown below at 6800)
     For customers it will be set at 6600


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

6) Reduced running temperatures.

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

8) Adjust radiator fan to come on at 205 degrees

   (Better for your engine when in heavy traffic.)

9) Free upgrades when/if we make improvements.

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

11) Answers to all your questions.....

PCV or PCFC fuel tuner - No longer needed.

All testing was done in house.

We can reprogram for the following markets:

USA & Canada only for now.

ECU reprogramming may not comply with federal safety/emission laws !!
ECU reprogramming may not comply with your warranty !!

Ivan's Performance ECU flash is for CLOSED COURSE COMPETITION USE ONLY !!

See Dyno Charts Below


The Stryker has many built in restrictions from the factory that cannot be removed from outside the ECU.

All charts shown with PCV now have fueling changes included in the ECU programming
Fuel tuner no longer needed !!

All dyno tests performed in 5th gear.

Our testbike did not have a stock exhaust available for testing
All tests have either a Cobra slip-on or Cobra powerport swept dual exhaust

Stock ECU vs. Ivan's ECU Programming

The stock airbox is very restrictive on this bike
Replacing it entirely with a high perfomance filter kit gives the gains shown below
Modding the stock airbox will not give the same gains.

Comparing the stock ECU to Ivan's ECU programming - both with open type air filter

Cobra Slip-on vs. Cobra Swept powerport duals - both with full performance package

Duals w/ stock airbox, Stock ECU, PCV vs. Ivan's ECU Programming, Open type air filter, PCV

Very impressive gains

When I have the opportunity to get some all stock Stryker runs on my dyno,
I will add the charts to show the gains from a bone stock bike
