I have never heard of a healer unit, but I just looked at the wiring diagrams for my car and the speed sensor is connected to the cluster and the ECU so its posable to install one that would only effect the cluster.
I can live with 2-3 mph off, that could be the difference between different brands of tires.

The data coming to the cluster is unchanged. I would suspect all you have to do is swap that sensor over. Do can you point directly to which chip it is?
I have the type UK one in MPH by the way.
I care not about 2-3mph especially if its reading low... its not like I go the speed limit.... ever...but my original cluster was spot on till 90+.
Ill gps verify when I go to work tomorrow.
As for healers. They have been making them for the offroad market for years to calibrate for gear/tire size changes.
