Just got my EFILive commercial kit today. So played with it tonite, did a short drive scan, read the stock tune and backed it up. Just for grins I decided to make a simple change and disable CAGS and attempt a reflash. Ran the test mode, licensed the PCM and all was well. I tried an actual reflash and got a 'Battery voltage too high or too low' message. It says it completed successfully but it did not change the stock PCM as I re-read it and compared.
The car is an 05 CTS-V and the nav system has a fan that runs when the key is on even though the system is off. Couldn't find the fuse for it in the dark tonite but do you think that is my problem?
Battery voltage always reads 14.3 volts so I doubt the battery is bad or is that 'too high'.
