6.3 Vehicle Bus PID Polling Rate
Unlike on the LMU-3030, the polling rate between each PID is a fixed. It is set to 150ms.
Additionally, the LMU-1300 no longer gives priority polling precedence to Speed and RPM PIDs.
For example, if there are three registered non-broadcast parameters, each individual parameter
is polled every 450ms
The LMU-1300 is different in that in-between each registered (non-broadcast) PID, the device
polls for SPEED and RPM, increasing the polling interval between each polled PID by a factor of
three.
On the LMU-1300, Broadcast PIDs, if available and registered on the specific YMME installed, do
not add to the polling interval. Below is an illustration of this;
6.4 PEG2 “Lines”
PEG2 lines are no longer considered “parameters”. A PEG2 “line” is only a virtual line, but in
reality they are not enumerated the same way as in a PEG1 script.
The Script (!SCR) section of a PEG2 file is one whole section that requires either deleting or
updating the whole section at once. No individual “line” can be updated.
The following differences should be noted from the LMU32/PEG1 environment:
PID 1
PID 2
150
PID 3
Polling Every 150ms between each PID
Polling PIDS:
