Hi all, went to help out a mate with his VX speedo the other night to change so the dash read correctly after going from 3.08 to 3.73. Went to do this by changing the PPK value which was ll fine except the largest value you can enter is 7500, when I needed around 7630 to be bang on. It there another way to go about this using a Tech 2? As this is a very basic change as far as modifications go really.

Sounds like it is only offering a range to suit standard options.
When i put my 3.9 in my old VX the tech2 only covered factory ratio changes so 3.7 (hsv) is the largest you can set it to. My speedo was always out by 5% still with the 3.9 due to this...

Interestingly my Maloo has an option of up to 10,000 pulses. So doesn't run out of range like the VX I did.

Maybe the Tech2 can only go as high as its factory setting ?

Maybe another type/brand may be able to do it ?
