• EFI Software Problems:
Often times, when EFI software related functions don't work properly, it's caused by a corrupted software download/installation.
I suggest completely removing the Holley EFI software from the "Control Panel", "My Documents" (Holley folder) and the
"C:Drive" (Program Files, Holley folder) and install a fresh EFI software download. Save your Global Folder somewhere.
• ECU Firmware Problems:
Conversely, often times, when actual ECU related functions don't work properly, it's caused by a corrupted ECU firmware installation.
As a last resort, you can try reflashing the ECU firmware version (LINK). The ECU firmware is in with the software download (LINK).
Also, try completely disconnecting the battery for 20 minutes (or 2 hours for some severe faults). This "resets" some unusual ECU issues.
May God's grace bless you in the Lord Jesus Christ.
