Cheers, Sammy,

Thanks for confirming. I phoned Motorsport Developments. (Someone told me they run/host this site). The guy said the same thing... that it'll hold the revs at 1100 rpm whilst the car is in motion, dropping it back to it's normal idle at around 900 rpm once the car comes to a stop. I'm feeling a bit more relaxed now

Do you know what it reads? Is it actual road speed or is it just telling the ECU that the car is still in motion?

My speedo is digital and measured from magnetic pulses from rear differential's bolts. If it's only cheking for movement I was thinking I could use the output of the speedo to the VSS on the loom.

Thanks again,

Neil
