Just getting started. Sent ? to EFI twice w/ no responce so thought Id throw it here.
Im an old autotap guy with no exp. here. I just recieved my software and trying to get started.
After loading software on laptop and connecting to vehicle. It will connect but no pids will show acctive. None are available. Im reading again through directions and the only thing I did not put in info is the Operating system Code. Is this nessasary and where can that code be found on the ecu.
Also when I only plug in the handheld programmer to the truck w/o the Laptop it says I need to upgrade.this is supposed to be the latest version. Help if you can Thanks.
