Smart cookie. Maybe do this instead on startQuery so that you can get the query parameters shown instead of question marks

$this->start = microtime(true);
$params_copy = $params;
$this->ci->db->queries[] = "/* Doctrine */ \n" . preg_replace_callback('/\?/', function($match) use(&$params_copy)
   {
      return array_shift($params_copy);
   }, $sql);
unset($params_copy);
