Default Calibrating HUD speed to Speedometer

On my 92 SSEi the HUD speed and analog speedometer matched near perfect.

On my 97 SSEi the HUD speed display is accurate to 50 mph. By the time I get to
70 mph on the speedometer the HUD reads 75 mph and gets increasingly worse as
speed increases.

I like my HUD and this is aggravating. Anyone have a solution?

Thanks, JB

That'* normal. After about 60 mph they add 3 to the HUD. This is to trick you in to driving a little slower. I just adjust in my head.

ROFLMAO....

I have a 97 as well. 50 or 60 take your choice. My take on it is the Series 2 cars are that much faster that the speedo couldn't keep up and probably had a case of whiplash. The HUD being digital is the correct reading to use for accurate speed.

My fix for it not being aggrevating is simply not looking at the dashboard speedo. It'* a poor and simple fix, but I figure the thingy (not a motor) that drives the needle is tired or lower quality..hence it'* lack of ability to keep up properly.

Both HUD and speedo needle are driven off the same wire from the PCM in 97.
