Re: HP Tuners Tutorials - Timing
Timing
Alright so I went out and drove around for about 8 minutes and got us some sample data. Using our basic timing channels here we can see that indeed the PCM is pulling out a tiny bit of timing based on the Engine Coolant Temp ECT as per the Collant Advance channel.
Now what's the point of this exercise? It is simply to make us aware of the things that the PCM may be influenced by to alter our base timing. It is not for us to go out and 0 out all these tables, leave them alone. The PCM is doing what it is designed to do, essentially protect the engine, from overheating for example.
This is different than zeroing out tables for the EGR and the CATs because those components no longer exist. If you are seeing numbers for your EGR Advance below, yet you have deleted it, you may want to revisit Section IV under Housekeeping.
