the cluster lights in my car quit lighting up,the lights for the needles still light up and all the guages also work fine other than the tach.The tach with the car on or off, i can turn on the parking lights or headlights it will jump up about 500 rpm.this all happened after i got my xcal2 installed.The only thing else i did was take out the computer to take out the old chip that was in it.And if it matters the tach is amazingly innacurate depending on how much gas i give it,like if i go wot the tach will go to redline stop and the engine will keep going and i know thats not right,it also reads about 3000 rpm at cruise.anyone have an idea?
