Hello everyone, I'm new to the EFI Live family. I have an 03 Silverado Duramax 4x4 with an 05 LLY Duramax engine and trans installed. When I installed the engine and trans, I had to have the fuel gauge re-scaled because it was reading backwards. I recently had to replace the ECU. So again, my fuel gauge reads backwards. I've purchased EFI Live to fix this problem and put some tunes on the truck. I've looked through the forum for help, but have been unsuccessful. Can someone help me with this? Right now, my truck is full of fuel, the gauge reads empty and the fuel light is on. Just trying to get it fixed. Thank you.
