Monitoring DSP status in the Scantool
You can monitor the DSP switch data using the following PID’s –
GM.E35DSP2_DMA (PC) or E35DSP2_M (BBL):
This PID will show if the DSP
2
tune is enabled.
GM.E35DSP5_DMA (PC) or E35DSP5_M (BBL):
This PID will show the current
tune number the ECM is using for DSP
5
.
GM.E35DSP5V_DMA (PC) or E35DSP5V_M (BBL):
This will show the measured
voltage at the ECM pin when using DSP
5
, useful for setting up the DSP
5
switching
voltages, otherwise just use the previous PID to monitor the DSP
5
program
switching.
