[928uk] 3 speed gear change rpm

[Paul R Smith]

Not that I know much about the devil's slusbox, but I beleive you may 
only get max rpm under "kickdown" conditions, so you may need the bowden 
cable telling the box you have WOT, the vacuum connection indicating the 
same, and the switch under the throttle pedal activated too.

The cable MUST be adjustable, you might get more help if you state the 
model year.
