I just installed a 03 Evo gauge cluster into my Lancer LS.. I decided to test it out and noticed that my tachometer was moving like the speedometer should and the speedometer wouldn’t move much when I was pressing the gas.. I know these two are in different positions in the Evo, but they should still work right? What do I need to do to fix this so it works properly?

 

Bought a 2002 lancer gdi engine in April, been busy havent got a around to get it fully ready. The previous owner havent drove it in years. what are the parts i should change???? oh i noticed that whenever i get to 2000rpm or higher the gdi eco comes off
