shiny_red_cobra : can you tell me what I need more I have ordered microcontroller? and I have a gauge from a VW Golf 3 is electronically controlled.

Okay thanks for the help will try to look at it,

Hello is there anyone who knows where to buy a controller for connecting a gauge of a car for LFS? or is there a guide to self build a controller? to sew I've looked around on the net without success. but have seen a lot of movies on youtube with people who have it connected to their computer.
Hope there is anyone out inside with some info.
