Hello-
The hardware is a Speartech Harness for LS that is made from a repurposed GM ECU.
Speartech says they set up the ECU using HPTuner software
Here's where I am at, I need the PID mapping from the ECU to provide the cluster maker to then be able to display:
RPM
Speed
Oil Pressure
Coolant Temperature
MAF temp or other data off MAFS, mass air flow sensor
Perhaps gear
The point is that Speartech doesn't get into this field, and while they are using the HPTuner software, they don't get into PID mapping, and apparently don't need to either.
Does anyone here know where this data resides?
I can't be the first out there looking to be able to do this.
I believe the cluster uses 500 kbps 11 bit, at least that is what they have tested, does this make sense?
