So I'm just getting started with hptuners in my first ls swap, a 5.3 from a 2002 avalanche + 4l60e in a 1966 ford LTD. Got it running without a hitch just a few days ago. I used hptuners to turn off vats and it worked fine, now I just want to make some small changes like using the gear/tire wizard, messing with DTCs, and change idle speed. The most noticeable change, the idle, doesn't seem to be taking effect and for that matter, I don't know if the other changes are doing anything. I go to idle>base setpoint > and raising it a couple hundred when the engine is at temp, write to vehicle etc. No matter what the idle stays at 550, just like it would stock. I apologize for being a beginner if I'm overlooking something obvious, I've followed tutorials and instructions and I don't understand what I could be missing to have these changes seemingly not register at all, especially since turning off vats went fine. Thanks for any input.
