I use a computech race air pro for weather but have not used the ET predictor part of it yet.

I never put faith in any et prediction software. I dial off my gut and the situation I am in at the time.

Wouldn't have been much predicting this weekend as every pass was a 5.57, but I looked at the weather off of it, got in the off the trailer bogey race Friday morning and won that with a 5.574 on a 57 dial.

I am getting good enough with it to do that now but the car has to work first. Getting That is harder than predicting the weather sometimes. I have tinkered with my setup for a year and a half to get it half decent and still things I want to try.
