Has anyone played around with the throttle mapping in HPTuners? I was reading another thread about ported throttle bodies improving response, and it seems the consensus is that our factory mapping is terrible. I agree. It is extremely sluggish and seems to be catered to the target Cadillac demographic of 60+ males that would typically purchase an STS. Of course, a ported or aftermarket throttle body will improve throttle response, but programming is also to blame. The factory settings don't specify any throttle opening until the pedal is depressed 15%. When the pedal is depressed 34%, the throttle is only opened 5%.
I played around with the mapping, and drastic changes will disable Stabilitrak and put the car into Reduced Power Mode. So I started making incremental changes and the PCM was more accepting. So far, I've been able to roughly double the throttle opening from 9-20% pedal depression. The car feels lighter and more responsive, especially during highway cruising. I'm going to continue tweaking to see how much more I can get away with until the PCM intervenes, and I'll share my throttle table when I'm done in case anyone wants to use it.
Has anyone else attempted to tweak this table or figure out a way to work around the PCM intervention?
