GM LS3 CAN message decrypting
Discussion
Hi,
a while since I've asked questions regarding this...I have a running GM LS3 and a crate engine which I am using to work out which CAN messages and bits pertain to specific parameters and how they are scaled and offset.
I've been looking at crank position sensor with a view to working out engine RPM data. The crank position sensor is seeing a revolving object but none of the CAN messages appears to show a change in data when this occurs.
Is it feasible that the ECU, not seeing the accompanying cam position signal, has decided there is a fault and so not broadcast RPM?
