4 Channel Wideband UEGO Controller Setup
Infinity Supports 4 channel UEGO CAN input for logging purposes. Modes must be properly set
up and if designated cylinders overlap, jittery values will be present in any overlapping cylinder
sensor. Description of different modes are as follows:
Mode 1: Cylinders 1, 2, 3, 4
Mode 2: Cylinders 5, 6, 7, 8
Mode 3: Cylinders 1, 3, 5, 7
Mode 4: Cylinders 2, 4, 6, 8
Mode 5: Cylinders 9, 10, 11, 12
Mode 6: Cylinders 1, 2, 3
Mode 7: Cylinders 4, 5, 6
*NOTE: Proper use of UEGO modes is vital for ensuring data is captured correctly. See 4ch
UEGO manual to configure modes or verify operating mode of controller.
A, B, and C relate to specific UEGO controllers
A refers to a controller in mode 1, 3, or 6
B refers to a controller in mode 2, 4, or 7
C refers to a controller in mode 5
