Weather station ET predictor suggestions
 

My system just died and I need some opinions on what everyone feels about the available systems.

I use a handheld Computech. Find it user friendly and accurate in the predictions.

I have a PerformAIRE Eclipse, which a lot of my fellow racers swear by but I swear at. I routinely run 0.2-0.3 under the devices prediction.

Here are the predictions and my ETs from last Sunday:
13.18/12.858
13.14/12.835
13.146/12.817

I burned hours trying to come up with a number to subtract from the machine for my dial, but If I had ignored it and paid more attention to the free time slip I would have just dialed 12.80.

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.

Re: Weather station ET predictor suggestions
 

Do you use a different data file for each track?

Re: Weather station ET predictor suggestions
 

I don`t find my PerformAire to be much help predicting ET, either.
Thought it was just me
Guess I`m not alone.
Thanks

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 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.

Re: Weather station ET predictor suggestions
 

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.
