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




My XV950 Bolt 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
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) Feels buttery smooth upon re-application from closed throttle (in all riding conditions).

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 7100 rpm

     

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) Free upgrades when/if we make improvements.

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

Our Performance Package for this model includes: (you need to call for pricing)

Slip-on or Full exhaust system - Call for pricing.

Power Commander 5 or PCFC (pre-programmed with Ivan's custom map)
-Or- other fuel tuner of your choice that is available from us.

A Fuel tuner is not required, but the smoothest throttle response and driveability are attained when
the fueling is matched to your exhaust and intake requirements at all throttle positions.

Power Commander products allow us to add or subtract the exact amount of fuel needed
to make your bike run the best that it can at any throttle position for your specific intake/exhaust combination.
This also leaves you with a totally adjustable fuel system that can be changed at any time, for any reason.

Best results are with a fuel tuner, and is recommended with aftermarket intake and exhaust changes
This is for proper and consistent fuel delivery with the changes that you have made to your bike.

Answers to all your questions.....



See Dyno Charts Below
Remember that these are only full throttle tests and do not reflect any driveability improvements

This bike is very restricted in "as delivered" condition
This chart shows the ECU power restrictions removed without any fueling corrections





With fueling corrections added & ECU flash, the gains are even more significant








After seeing the above charts,
This is why a fuel tuner alone cannot offer what is needed to make this bike perform correctly

The stock ECU is too restricted for fuel adjustments alone to correct it's problems


 

 

Un-restricted ECU w/corrected fuel vs. stock ECU w/corrected fuel
Stock intake and stock exhaust for these tests








Exhaust & intake tests


The airbox is very restrictive on the Bolt (8-9hp)
If you want all the power, an air filter kit is a requirement

 



Stock muffler is not as restrictive as one might think
Slip-ons still give 4-5 hp in the midrange and appx 2hp at high revs







V&H duals work very well on this bike







Slip-on systems seem to give the most overall power increase on this model......
A whopping 23 hp @ 6500 rpm w/ my ECU performance package !!







TBR comp series 2-1 full system









Slip-on vs Duals
