SIDI Speedo Calibration after Diff Change

[Jarp]

G'day,

It was suggested on the forums that you guys may be able to help with this prob. I've had the diff changed in my SV6 SIDI from 3.27 to 3.7 and as a result the speedo is out by 13%. Can you help with this?

Cheers

From my understanding this should be able to be re-calibrated using a Tech 2 tool, which any Holden service center should be able to do. Could be wrong though

G'day thanks for the response. I had it at Holden today and they were unable to do it nor were Gentech (Walkinshaw). Very frustrating I must say.
