The software doesn't know what gear you are in? Also the drag coefficient seems vastly different. I think its safe to assume your doing it wrong

 

[Jonny1*2]

you're supposed to do it in 3rd really. Needs to be on a flat surface with no wind etc. Hard to do correctly, and it's a very rough estimate compared to proper rollers

Also you have set the weight at 1200kg's, a non cup ph2 should be 1100kg's

 

[vivelesport]

1200,1110 car + 70kg me +fuel and replacement tyre
I'm remembering,when I do it in 3º gear the road has a small inclination,then I try again in 4º gear at 3500 and

then the road becomes totally straight,it's a long straight road because there is an airport

 

[Russ_16v]

Dial off 15odd KG's for the tyre as thats in with the curb weight

Wrong, its actually working very well if used under the right circumstances.
Best way is to make 2 measurements in opposite directions.

PERFORMANCE ANALYSER works good,I don't know if I have used it well,I think I have used it correctly

 

[Jonny1*2]

I stand corrected , my bad

 

[Andrew Cooke]

were you getting a bit of wheelspin in 3rd?
