Enmity Posted December 10, 2005 Share Posted December 10, 2005 If you replace the stock pipes with cat. convertors for some louder pipes, do you need to have the ignition curves remapped for the drop in back pressure etc? I have read conflicting reports in this. About to head out for 5 weeks Around Australia tour =) Thanks! Mick Quote Link to comment Share on other sites More sharing options...
AZITPRO Posted December 10, 2005 Share Posted December 10, 2005 I think you can run OK without remapping, but you will run much smoother with a power commander and a custom map for your bike + a small HP gain. Quote Link to comment Share on other sites More sharing options...
beondwacko Posted December 10, 2005 Share Posted December 10, 2005 Typically , when you change the exhaust or modify an exhaust on a bike , it's not so much the ignigtion or spark curve you need to change , it's the fuel curve/ratio that needs to be modified. Your bikes ignigtion curve is controlled by the computer. It's equipped with a "Knock" sensor that retards the timing when ever it detects pre-detonation. I have never heard of anyone re-flashing the factory ECU to alter the curve before. Could somone with more experience with the XX shine some more light on this please?
