So, compared to GPS, my Speedo is consistently 5mph too optimistic. My tires are 195/65-15. I’ve read in other threads that has shown to be a good size for correcting error.
So, not really wanting to go taller still, is there any other way to calibrate the Speedo? Thanks, Van |

One of my "must try that one day" projects is sourcing a decent GPS speedo as a core and adapting it to a 911/914 speedo housing. Much like the tachs I modify using the Bosch cores to get a more modern movement, different RPM range / fascia, etc.
The only "non period" aspect would be that all of the GPS units I've seen use an LCD display for the odometer - I could live with it though...... - Tony |
