If you already have a pscan then defintely, yes. An OBD socket is under £5 on ebay or Amazon.

It's much easier to calibrate the MGF EPAS if you have a pscan. There's a video here

Just try to make sure that the OBD socket (and therefore pscan) is earthed as near as possible to the earth of the ECUs that you are using. This can be a problem with MGFs because the engine ECU seems to be earthed a long way from the socket and it causes problems. It isn't such a problem with front wheel driver Rovers for some reason. pscan doesn't really care about chassis ground, it's trying to talk to ECUs so it's the ground of the ECU that counts.
