VFD/VHX/HDX wiring tip:
When connecting to a VFD, VHX or HDX display system you can easily get power and ground from the control box
RESERVED+ (FUEL+) and FUEL- terminals. These terminals are normally not used. Connect the BIM-xx-1 adapter harness
RED wire to the RESERVED+ (FUEL+) terminal and connect the BIM-xx-1 adapter harness BLACK wire to the FUEL- terminal.
Troubleshooting quick tips:
While the BIM is operating, the dot in the upper left corner of the display will indicate the status. On steady indicates it is
powered up but not receiving any BIM bus activity. Flashing indicates it is communicating on the BIM bus.
If the display shows "" then it is scanning to try and communicate with the EFI system bus but cannot get an answer. To see
the sensor and channel status on the BIM display, press and hold the switch. The display will cycle through several screens.
The first will show the bus type ("" Holley EFI). The next screens will indicate which (if any) extended data is available: ""
for intake/manifold temp, "" for engine oil pressure.
To set or change the ID number:
The ID will not normally need to be changed. The fuel PSI and A/F ratio readings both use bus ID's so if you have other BIM
units connected along with this one there is a chance of ID conflicts. This can easily be resolved. If fuel PSI or A/F ratio is not
showing up in the BIM setup menu on your system you may need to resolve an ID conflict. The following procedure will allow the
BIM-01-2 to automatically select a new, unused ID.
•
Hold the switch on BIM while turning the key on. The BIM will show the current software code.
•
Release the switch.
•
Press and release the switch until "" is shown on the display.
•
Press and hold. "" will be shown while the BIM is scanning the bus for other BIM units.
•
When you see "" shown on the display release the switch.
•
The BIM unit will now go back to normal operation.
HDX TIP: Intake/manifold air temp, Fuel PSI, boost and A/F ratio will be displayed in the group screens if activated through the displays>>group set
menu setup.

Problem
o
BIM will not light up at all
BIM display is scanning ""
o
o
BIM has a steady dot lit
BIM display shows ":"
o
Possible cause
• PWR wire does not have power.
• Connect to a different ground location
• Power/data harness is damaged.
• Module is damaged.
• EFI adapter harness is not connected
• The EFI system is not compatible
• The EFI is not powered on.
• The EFI CAN is not configured to "Racepak"
•
Interface cable is not connected
•
Interface cable is loose.
•
On VHX systems, the BIM display for this is disabled.
•
Data cable is damaged.
•
Another module on the bus is damaged or connected
improperly.
Solution
• Connect to a location that has +12V key-on power.
• Inspect harness and repair or replace.
• Return for service. (See Instructions below)
• Connect the appropriate harness to the EFI CAN.
• Verify compatibility.
• Verify EFI system is powered on.
• Verify CAN settings within EFI software.
• Connect the supplied data cable between the BIM
unit and the gauge control box.
• Make sure both ends of the cable are seated.
• Follow instructions in VHX manual to enable the
BIM display screen.
• Inspect and replace the data cable.
• Inspect other modules on the bus.
