Occasionally, we find in other countries that the typical oxygenates used here in United States which promote clean air (such as Ethanol, TBA aka tert-Butyl alcohol, Hexane, MTBE, etc) may be missing; some countries use them, some countries do not. If the oxygenates are missing, our mapping can be extremely rich for use with your fuels. This is indicated by sluggish performance, low rpm ‘surging’, a strong fuel smell from the exhaust, and/or excessive residue at the exhaust tip and/or poor dyno performance.
CAUTION: DO NOT USE BROCK’S PERFORMANCE MAPPING IN COUNTRIES WITH FUEL USING MORE THAN 10% ETHANOL – SERIOUS ENGINE DAMAGE MAY RESULT. CONSULT A PROFESSIONAL TUNER OR LOCAL DYNOJET TUNING CENTER FOR MORE INFORMATION.
This is a simple problem to correct when using the PCV with the Autotune module. Simply auto tune with a target air fuel ratio of 13.2 across the board if normally aspirated (12.0 for the Ninja H2), and allow the bike to make the appropriate adjustments. See your Autotune instructions for additional details. If your bike does not allow the use of the PCV, typically an across-the-board alteration of our mapping of -5% is enough to allow the map to function adequately. Please note: Map changes beyond this amount are not recommended.
If this does not work in your application, you will need a custom map session to match your country’s fuel to your motorcycle and new exhaust (and perhaps ECU flash), or the addition of an aftermarket A/F unit such as an Innovate unit or Daytona WEGO which will read your air fuel and allow you to alter your map through your Power Commander to make the appropriate changes. Importing canned fuel, such as VP’s MR12, MRX02 etc. will also allow you to run our exact mapping.
Also, make sure you save all of these maps to your desktop in their unaltered state as received. Rename any maps which you alter using your Autotune. This allows you to go back to your base maps at any time. If these maps become lost or corrupted, simply resubmit a previously approved form (below,) and we will resend them ASAP.
