Focus Diesel reprogram to Petrol calibration

[miketmechanic]

Has anyone reprogrammed a diesel rev counter to a petrol version at all ?

At the moment i have replaced a petrol dash cluster with a diesel cluster and as you can imagine, the revs are all wrong so i want to change it so that it runs as it should.

I am sure this can be done and am putting out to you guys to help me out if you can please ?

Many thanks
