I'd say the "1" digit on the display is crapping out. Is the car running any differently than it did before?

sounds like a wiring issue. where is the unit grounded? i would double check to make sure you have a good clean ground.

Well i bought the car for the engine/turbo kit/electronics so put in my jdm front gsr, so i will be redoing it all soon when it goes in the other car. BTW now it reads nothing as if its not wired up. Just a blank screen.

after about 3 years with my m300 some of the digits went out. I opened it up and got the part number of the screen and replaced it. It took a while to find a vender that would sell only one, most wanted for me to buy a minumum of 100. I think it was less than $10 shipped. I don't remember where I got it though. It was fairly easy to replace. If you know how to chip an ecu, then you'll be fine.
