SKiddell said:A half decent rolling road operative will correct for any temperature/air pressure changes (above or below certain values) so the temperature shouldnt make significant differance...its called a "correction factor"
There are a number of differant "correction factor" models used by differant dyno set ups
SAE-J1349
DIN 70020
EEC 80/1269
ISO 1585
All in all they do the same thing....correct for temperature, pressure and humidity
If your "dyno" operative doesnt do this, tell him to get his old job back at Halfords
unfortunatley we went to interpro on a hot day it wasnt pretty
