Would it be possible to upload the pics this week?
My car currently shows 40mph when I'm going 48. I would love to have this live!
I did this on a previous 240, as I recall it?s as simple as finding the 50 ohm resistor, and replacing it with a 100 ohm micro potentiometer set to 50 ohms, then adjusting it so the speedo matched my GOS app.
I glued the pot behind the plug for the clock adjust stalk hole, and can adjust mine without removing the cluster.
I used something like this, multi turn trim pot.
