My efi live v2 wont read or scan a 98 fbody that im trying to tune but has no problem with a 01 vette that im tuning as well.

The fuse for aldl is good and tuner cats reads and writes to the car just fine. I did get it to read once after resarting the computer but it wont do it again.

Has any one exsperienced this is there a new up date and firm wear im missing or some thing any help would be great.
