I drive the wife’s 62 plate Citigo now and then which has the PID unit.
I struggle trying to see the speedo accurately (30MPH); especially as 30mph is not even marked with a number or highlighted in any way, it is somewhere in amongst lots of white markers between the 20 & 40mph. At a glance I find myself having to look for too long to check this.
All other modern vehicles I drive these days have the option of a digital readout, which is so instant.
Are there any known ways of getting a digital readout; PID perhaps with coding?
Or is it get a crappy nail vanish line painted on the outer clock glass and hope it’s close?
