dyno SAE correction numbers?

[zxmarekxz]

My original dyno has a 1.03 SAE number next to it while my newer one has .99 . Is this number dynamic based on environmental factors or is this something set manually?

thanks

Not set manually by the dyno operator. Based on atmospheric conditions at the time of the dyno run.

So the first time your car actually made 3% less power than it shows, and the second time it made 1% more than shown. SAE corrects for temp, barometer, elevation, etc.

I believe you have that backwards there.

1.03, means there needs to be 3% added to the HP numbers. As to wear .99 would take 1% away making less HP.

Post your dyno's or give us more info. But I believe I am correct here.

either way its fine. it would make sense that .99 would lower hp as it happened it 10* cooler temp. I just wanted to see if it was automatic. tx
