Is there any way of calibrating a suzuki Sierra's speedo

[stockman]

Yes. But not the odo.
It was recently discussed so should come up with a search.

You can spend lots of money on a little gearbox on the speedo output, which will fix both. I had to do it to get my 31s engineered. About $500 from memory.

Thank u I will check that out $500 is way to pricy I will prolly just operate on the speedo,I've got to just search what's said on auszookers

The simplest option is just to buy a GPS unit. Marks4WD Adaptors in vic could do a ratio box for $300 when I asked them. It was a third of the price to buy a GPS. Unfortunately if your looking at getting the car engineered then a proper fix is the only option.

It seems in qld we don't have to get our tyr size engineered, we just don't have has many options for legalarty in larger tyres as other states
