I saw one of these at Grattan Raceway and then Road America in the 2003 season. It was one of the first and they had serious engine management problems. I saw the same car and owner at Gingerman Raceway earlier this year and he says that they have all the problems tuned out. His car had the AEM EMS system on it.

BTW, it's not nearly so ugly in person. For some reason the pictures do not do it justice at all.
