Has anyone tried this method to calibrate their speedometer?

I was told that Yellow Box works and is half the price! I used one on my S2000.

Email their support and they will get back to you with what model you need to buy.

$200+?

Ouch. Ya... Yellowbox or Speedo Healer are only $100.
Programming is a bit more tedious (set dip switches), but the end result is the same.
I've got a Speedo Healer on my bike and it works great.

 

I did a little research on the Hypertech Speedometer Calibrator I think I might have started a thread. Someone posted that they had it and it was super easy to install and setup. I am under 36K still in warranty and so my truck reading a little slower is a good thing.

Once I pass 36K this is what I will be getting. Also I have an UltraGauge which display the correct speed.

 

Been conversing the last couple of days with a gent who has one and he said that he has to pretty much tear the entire left side of the dash apart to access it.

But I would imaging any of the 3 would install the same way unless there's a junction connector in one of the kick panels for the VSS.

 

Looking for some additional info on the Hypertech calibrator. Anyone done a write up for the install??
