Not possible I'm afraid. The switchable maps was a feature of older cars where the ECU had dual maps; one for manual cars and one for automatic cars. When used in a manual car, the other map was not used (I'm not sure it was dual maps, but dual somethings!!). Anhyhoo, the Hawkeyes don't come in automatics, so the dual feature ECUs that could be used to provide two cycles was dropped. This is the gist of it but I'm sure some of the terminology is incorrect. What do I know about cars?
Silver Bullet? I like that. I used to call my MY04 Toyota Celica that, but your chariot is far more deserving on such a title. Be carful when mapping your bad boy; I have lost an engine and a gear box so far!
Good luck with it my man, I'm sure it will provide you with as much, if not more pleasure as Black Beauty.
