Weather station ET predictor suggestions

[Ed Wright]

Crew Chief Pro software in your laptop. Enter your weather data along with your runs, after three entered at a given track, it will predict dead nuts, if your car repeats well.

Do you use a different data file for each track?

I do.

Ed's statement about 'three runs' is a little misleading. The software only predicts ET based on one single run that you choose as your base.

Sometimes I'll flip it through a couple different 'base' runs to see if the predictions match.

I've spent a lot of time analyzing runs and tweaking the formulas, but the stock ones are pretty darned good. Probably gotten myself lost more than I've helped.

It does recommend having three runs, it does have you put up a base run. My guess is it looks at the changes between previous runs to reference how your car responds to weather changes.

It does a better job that anything else I have used. It will predict from one base run. Predicts mine closer if I have a couple other runs.
Thinking one run is all is needed is saying every car will pick up, or slow down, the same with the same weather change. They don't.

I have the Perform Air computer based weather station. Race works software is easy to use and seems to be right on the money with my car. It takes a bit to get used to the program and how to get it set up. The price is good and they have good support. I would recommend this system. I don't have the paging option but you can add it on later. One thing about the prediction software is good info in and good info out. I had a hand held for years that was good and it died on me. The computer based is much better.

Mike,
What do you use for the comparison base. DA, ALT A, Barometric pressure, ??

It asks you to. If your car dead hooks everywhere, I would think it would not matter. I just follow the instructions. Been married 52 years, learned to do that.

My buddy does use a unique database for each track.
