If it's no Scottish it's CRAP!
Ah! so your speed detection is off the rear ABS sensor (at least it is on Roadsters)
Make sure that your pulsar rotor is not bent or damaged
You don't have any MIL light or codes set if you read with TuneECU?
Also if you have the DS version that plugs into the Diag connector, the learning procedure is different
However I would not attempt to change that until you identify why the speedo is not registering
