It is important to understand that if you alter your stock ECU from the Suzuki base map using PetricK's ECU editor software/or Boost by Smith etc. (other than raising the peak rpm limit, 400 RPM max increase is our suggestion, and removing the top speed limiter) that our Power Commander and Bazzaz maps will no longer function properly and our technical support staff will not be able to help you troubleshoot controls-based problems.  We also have no way of increasing the RPM tuning ceiling of some maps, you will need to consult the manufacturer of your ECU modification software to address these issues.

Our support program is based on the OEM configuration so that all bikes are on the same page; the moment you alter this, you have created a custom configurationand will be on your own just like any other racer or tuner.  Please save your OEM base map before making any adjustments to the stock ECU.  This will allow us to help you later if you decide to return to the OEM settings and take advantage of our proven combinations using a Power Commander.

The same holds true if you alter your stock ECU with a Yoshimura clicker box or a Factory Pro Teka unit.  ALL maps supplied by Brocks Performance are designed to add or subtract from the factory developed maps stored in the stock ECU.  The ONLY way our maps will function correctly is to return the ECU to its zero settings.

Guys,

HELLO!

The new 2008 Hayabusa is almost identical electronically to the 2007 GSX-R1000.

I will be adding information as we figure out Suzuki�s Fastest bike EVER! 

1:  Stock O2 sensor: First and foremost, I need to clear up some items about this new little gadget.

The 2008 Hayabusa IS **NOT** CLOSED LOOP!!!�in the traditional (automotive) form.

The Stock O2 sensor MUST BE REMOVED from the bike for proper performance. In a nutshell, this sensor is 'emission control BS' to help the bike pass more stringent (Euro 3 and Tier 2) air quality standards. Its job is to DRASTICALLY LEAN the air fuel mixture at cruising speeds (ONLY). Even if you have our map to correct this, the stock ecu will continue to remove fuel with the sensor installed�.effectively rendering our map useless from a performance standpoint. 

The simple fix (at the moment) is to install a power commander since it includes a jumper to remove the sensor from the wiring harness without letting the check FI light flash. This prevents the stock ECU from attempting to ruin our mapping. We also have these jumpers available for sale without the power commander. Call 937-912-0054 or contact sales@brockracing.com for more details and/or pricing. 
Once the jumper plug and power commander are installed, the mapping works just like the older Busa�s.

Please note: We have now added an O2 bung to allow the use of a Bosch (5 wire) sensor for use with our Innovate Technology A/F Meters (or a wideband unit, etc...) as a convenience to our customers. The stock sensor will NOT fit our bung which is intentional since you don�t need it anyway�especially for race use. If you decide to run an after-market 02 sensor, simply drill the exhaust in the center of the hole and smooth the area at the bottom of the bung/pipe with a Dremel tool or similar small cutter. Be careful not to harm the threads on the bung; we suggest entering and exiting the bung without the tool rotating. The stainless steel of the pipe is only .028 inches thick which makes this an easy job for most individuals with moderate mechanical skills.

If you do not have a power commander, then you can simply leave the stock O2 sensor plugged in and tie-wrap it up under the fairing until you purchase a power commander. We also have a bypass plug available separately to prevent the FI light from flashing if you do wish to purchase a power commander. Call our sales department (see above) for more details about Suzuki Bypass Plug part # 76423019.

Note: The check FI light will flash if the sensor is removed from the bike without using the plug. We have not investigated the performance effect of this problem, and we won�t. If you want your bike to be as fast and smooth as possible, you need a power commander with our map.

As always, maps are easily obtained by filling out a map request form. A shorter map form can be found here: www.brockracing.com/dealermapsupport.html 

**IMPORTANT**

2.    Removal of the Secondary Throttle Plates IS NOT RECOMMENDED on the New Busa and the maps included ARE NOT intended for use with the plates removed. The 2008 Busa is as close to factory RACE BIKE as you can get...the secondary plates are used to smooth the power NOT restrict power as occurs with other bikes (like the ZX-14). At this point, we only see them functioning with the mode switch and low cruising speeds for emission purposes which are eliminated with the use of the power commander, our mapping, and jumper plug.

3:  TRE use on the Suzuki�s: Note: The TRE-002 simply locks the bike into the 5^th gear map in the stock ECU which KILLS POWER after adding some additional torque in the lower revs. This power killing is a good idea on stock and short wheelbase Busa�s.

Note: The gear position indicator is stuck on '5' all of the time, the 'neutral' light doesn�t work, and the bike will not run with the kickstand down�.but the 186 MPH limiter doesn�t work either.  

4:  All short stacks: 2007 GSX-R1000 Short Stock Velocity Stacks (Suzuki part #13881-41G00). We use all 4 short stacks to help boost the high RPM power of this bike in conjunction with our exhaust design. This works especially well with our extended ECU mod.

That�s it for now. More to come soon. 

Good Luck and GO FAST!
