Similarly, sometimes users would like Lambda (AFR, FAR, PHI) readings to match other
instruments such as gas-bench analyzer calculated values (ex. via Spindt or Brettschneider) or
company “heritage” Lambda measurement techniques. The Delta Lambda Table (found in
the task “Lambda/O2 Delta Tables”) allows to user to add a number (a “delta”) to “LAMR”
calculated by the LambdaCAN* module giving the “LAM” parameter:
LAM = LAMR + Delta Lambda Table value
(interpolated from table)
AFR, FAR, and PHI are calculated from “LAM”. A Delta Lambda Table can be created,
edited, and saved as a text file (.txt) on your PC. The file must be downloaded into the
LambdaCAN* module where it is used. File LA42.TXT (for LSU4.2 sensor) or file
LA49.TXT (for LSU4.9 sensor) can be downloaded to make LambdaCAN* modules match
default ETAS LA4 data (see Appendix D). Unlike the sensor calibration information (i.e.
span) which is stored in a memory chip in the sensor’s connector, the Delta Lambda Table is
stored in the module.
