so open loop and closed loop are 2 different things, what do they do? I thought it had to be in a certain loop per NHRA, just asking because I don't know?

so would an open loop just be a piece of rope, or string?

Tuned properly in open loop is as fast as closed loop.

Hey Toby
This question has nothing to do with these guys but how the start system works. I have meet both. Anybody correct me if i do not have this right, this is how I thought it worked. Once a car pre stages the other car has 45 seconds to pre stage. Once a car stages the other car has 7 seconds to stage. Or does the starter have total control over the pre stage time? Want to know how it works for future incidents if this happens to me. |

As far as open loop VS closed loop, one relies on a base fuel map vs the engine rpm or throttle position. The other ties into the on board Global Positioning System and wheel speed counters and makes it extremely consistent.

Never heard of a pre-stage timer, but I believe you get 10 seconds to stage in most of the sportsman classes and 7 seconds for the pros. |
