interesting , but like you say you should start a proper thread for this.

the car (or code) doesnt 'know' its on the dyno , so whats the factor indicating it is ? (airflow)
be good to know the type of dyno too  :happy2:

Ah nice one Carl that explains a bit more to me as i've had similar issues on my KO4. Was on the rollers nearly half a day and done our heads in.

Janner_Sy:
good news, JBS now have the Pump internals in stock, so if anyone wants some get in there quick.

mine are in the post as we speak :party:

I found this years ago with the impreza. Vehicle speed against wind speed is great factor to remember. Fans etc used on the rolling road setup are never controlled to match the vehicle speed on the rollers so you never get the same results as when on the road. There are a few rolling roads out there that match fan/wind speed to vehicle roller speed. Or, i should say were out there. Not looked into this for a long time now.
