I'm trying to upgrade the instrument panel in my astra to one with a rev counter. I've tried to install one from an SXI but the speedo can be about 30mph out and the rev counter doesn't go any higher than around 4000rpm.
Another thing with it is that the lcd display for the trip and mileage is different to my original so it only displays "Pr09".
I presume its just a case of getting it calibrated to my car, if it is does anybody know where I can get this done?
I have been in touch with Vauxhall and they haven't been much help.
