VERSYS 1000 ECU FLASH

                                                            Now for 2012 to 2018 Versys 1000 models!





Hi Steve,
I got to take the Versys out on track. Weather was a little wet, then damp, then it dried out. Overall, it did amazing! The throttle response is spot on, and it feels like a noticable increase in midrange. This may be just a result of how smooth it is, but I like it. In the wet, that 1%-5% throttle control is important, and it was perfect.

Job well done!

 2015 versys 1000, decatted stock header



We are seeing some real changes in the sport touring world. Manufacturers are leaning towards either hypersport touring, or adventure touring. The Versys 1000 is part of the upcoming breed of "asphalt adventure" bikes. That's not to say it can't be used offroad... my 2015 V1000LT is used offroad everyday on sand trails and dirt roads. In fact it's the bike I ride the most, as the wide bars, upright seating position,low center of gravity and relatively light weight make it a good all around choice for me. As such, I demand very good low rpm and light throttle operation for offroad, and higher power for on road use. My flash has resolved any throttle jerkiness from idle all the way up. Power increases, particularly with the addition of a header, are substantial. My direction for this flash is very refined throttle control while increasing power.




     All tuning was done with 89 octane / 10% ethanol pump gas. No need for higher octane. All tuning was done with a stock air filter and airbox, and an otherwise stock bike with stock gearing. Both extensive dyno work and datalogging while real world riding were done to build this flash.


       This is a comprehensive flash, and includes the following changes to the ECU:

    - Intake air pressure fuel maps optimized and different for each header setup;
    -Throttle position fuel maps optimized and different for each header setup;
    - Extensive reworking of the ignition timing table
    - All gear based secondary throttle maps, both accel and decel optimized;
    - Deceleration fuel cut is defeated, off/on throttle is smooth as butter!
    - Rev limiter is raised 500 rpm to 10,000 with the stock header, 10,300 rpm for the Delkevic and Black Widow header    flashes.
    - Engine cooling fan on temp lowered 10*;
    - 02 sensor and light disabled;
    - off throttle fuel cut deleted, fueling corrected so there is no exhaust popping on hard decelerations;
    - pair light shut off should you want delete the system with block off plates;
    - Optional 1st gear wheelie suppression - Wheelies are cool, but they're not fast. I have an optional map for 1st gear wheelie suppression. I run this map, but others may not choose to - you decide what's best for you!
    - Excessive deceleration braking has been eliminated. No more feeling like you're going over the bars on a hard throttle close. Deceleration is appropriate and gear specific;
    - upshifts are smooth, no more jerkiness.
      - Strong Idle even at 900 rpm, no more stalling while trying to get moving!

                                                       DYNO CHARTS

       The purpose of the following charts is to help you decide how you may want to modify your Versys1000, and which exhaust choice is best for you. All runs except #6 and 7 with slip on mufflers have no DB killers installed.


1) STOCK vs all STOCK with a Shoodaben Engineering ECU FLASH.

     

2) STOCK VS Delkevic full exhaust system with Shoodaben Engineering FLASH. Note, the Delkevic header is the same as a stock decatted header without the balance tubes. If you are decatting your system, these results would be typical.
  
3) Stock VS  Black Widow full system with Shoodaben Engineering FLASH.
  
4) This chart uses the STOCK MUFFLER  and compares the Delkevic Header w/ Shoodaben FLASH  RED VS  Black Widow Header w Shoodaben FLASH.
       As you see in comparison to the full system dyno charts, the stock muffler is not very restrictive. If you are on a budget and have to choose between a slip on muffler (which will get about 1 hp on a stock header) vs buying a Black Widow header... buy the header.
  
5)   Black Widow header / open slip on muffler / Shoodaben FLASH  VS Black Widow Header / STOCK muffler / Shoodaben FLASH.
   BTW the open systems (open slip ons on headers) get LOUD. Even the stock muffler is loud once the cat is gone. As you see, there is very little power difference, but the flow characteristics change, and the dips in the midrange change places. The dip is about 3# TQ, and due to header design. The Delkevic header dips similarly.
 
  
   6) Tricking the system.... Below are 2 charts with the Shoodaben Flash, BW header and Delkevic slip on,  WITH and WITHOUT the DBKiller. Below you'll notice the DBKiller  is really a POWER KILLER... and we don't want that. (Blue is the DBKiller)



     7) On the other hand, we need some back pressure to bring the light throttle response back. Here I have drilled 48  .187" (3/16") holes through the sides of the DBKiller, and reinstalled it. The result is imparting back pressure at light throttle settings and bringing light throttle response back, and no meaningful restriction of WOT power. (blue is the drilled DBKiller)
                                    THIS IS WHAT TUNING IS ALL ABOUT

     


   


                                                                        Notes on headers

     The Delkevic header is a copy of the stock header . It's a 4 into 1 with a bifurcating plate in the collector. It is a small tube header, 32mm head pipes, same as the stock unit. It is sharp to throttle input at lighter throttle settings, but lacks the capacity to make much more power than stock.It is well made, and fit / finish is good.

     The Black widow header is a true tri-y header, which I prefer for all around power. It has 38mm head pipes, and I would consider it a large tube header for this application. It displays very well on the dyno, although I'm not in love with the torque dip around 5000 rpm. It feels softer to light throttle input (regular riding around) than the Delkevic or stock headers. It's slight, but present. This can be brought back on line by imparting some back pressure, see dyno chart #7. Clearly it's the power winner at WOT. I also notice a fuel economy improvement with this header, vs stock or the Delkevic. The pipe is well made, fit and finish are way beyond what I would expect at this price point. I will be keeping the Black Widow Header on my Versys 1000.
