Does anyone have any idea as of why my scangauge readings would be off?

There are only a few,

MPG [WAYYY OFF] 1400 MPG..
Horse Power [.5 HP]

And probably one more..

Thought it could be VVS but speedometer reads fine on gauge and dash.

I emailed scangauge and they just sent me another one...

It works on every vehicle but mine.. FIGURES.

 

I'm having the same problem. Everything works except fuel consumption numbers. (Haven't checked the HP figures though)

Have you found out what's wrong?

 

guess its just a Land Rover thing..
Sucks because thats the ONE thing I really wanted it for.

 

Talked to their tech support today. The only workaround to get the right correction factor is to use the % correction function. You either keep your finger forever on the button to get 10000% increase or increase the engine size to the max possible, and correct using the % as soon as you have a significant consumption value and redo it again a few times (% x % x %...)

 

ill try anything
