Engine up to temp.
Block wheels
Start and put in D for 5 minutes
Put in Park for 5 minutes
Shut off.

That straight from my Helms Manual

will this speed up my truck learning the new idle speeds?

I boost not because I have to, but cause its who I am


People in general dispise others who are better at what they do than they are, in fact they can create whole cults to mock you due to their lack of intelligence and character.... we all handle this differently.

Agree,...once you hit your Adaptive learn temperature you should be good.

What is the temp when it starts to learn?? operating temp?
After my tune, I drove it on the highway not on the streets so it still does not want to idle in R or D, well it still stalls, not as bad as before the tune, but it is still stalling.

I want do my part in letting it adjust itself before I ask my tuner to bump it up some more or what ever magic you do inside those PCM's.

What would you suggest as a relearn procedure
1. unhook battery, how long??
2. reconnect
3. As stated above:

Engine up to temp.
Block wheels
Start and put in D for 5 minutes
Put in Park for 5 minutes
Shut off.

its stalling? sounds like your idle airflow might be off, or maybe too low of idle for your cam.

Well I just tried the idle learn and it was not having it.
now I will get out the wrench and disconnect the battery and try it again later. Aside from this small issue the truck pulls real hard, it is a beast when you get the down shift that puts the rpm's in the 4k range...screaming!

With the bigger cams in an ETC truck, the idle learn takes longer. After you've driven it around in the city a couple of days it will be fine.

thats so true. the ETC has a lot of learning to do. It has gotten better everyday, still funky sometimes...but I was merging today and it down shifted @ about 20mph....the RPM's jumped and my truck was flying! I need to get some track times...
