We run them in both ways mate its just our sensor you attach to the ht lead is faulty and were waiting for it..
Mike guerney came to ours the other week and went through everything and said its all fine and you can run either way as wheel slip is so obvious on the graph,not only that we dont run the old dos system we run the digital one wich is better for this apparently..

When you run a car for multiple runs you know if one is wierd and if its wheel spun..
