Component relearn?

[onealmx11]

I've had my batt. Disconnected for a few weeks while ficm was out for repair. I've read a few posts on certain relearn procedures. I'm unclear on what I need to do. I drive 2004 f350, 4x4, torqueshift granny. Any ideas on if I need to relearn anything (turbo or tranny) ?

just drive it normal.

Just drive her normal so the trans can relearn, usually less than 50 miles.

If you have an early '04 with the '03 motor, you might have to do the VGT relearn.


KAM (keep-alive-memory) reset & VGT learn procedure
1. Drive the truck until the engine and transmission have reached normal operating temperature.
(The VGT learn procedure requires that the oil and coolant temperatures be at normal operating temperature)
2. Flash truck back to stock (Only need to do this if running a tuner or module)
3. Turn on the headlights
4. Disconnect both batteries
5. Short out + to - battery cables to each other (Make sure both batteries are disconnected before doing this).
6. Let truck sit like this for 10-minutes
7. Turn off the headlights.
8. Re-connect batteries
9. Cycle the key to the run position twice. Pause in the “ON” position each time until the wait to start lamp goes out (minimum 5-seconds) and pause in the “OFF” position each time for 10-seconds to be sure the PCM has "gone to sleep".
10. Start the truck and let it idle for a minimum of 5-minutes at normal operating temperature. This allows the PCM to learn the EGR valve closed position value. Also you will likely hear the turbo pitch change several times during this period as the PCM learns the necessary duty cycles for accurate VGT control.
11. Complete the road test Drive Cycle:

15 miles of mixed driving (*should* be enough in most cases) to allow the PCM to "re-learn"
its adaptive strategy. Note: Anytime the batteries are disconnected, the PCM will throw the
P1000 code until the “Drive Cycle” is completed. As for the Tow/Haul mode, the transmission
must re-learn your driving style and loads hauled again as this was cleared when the truck was
re-flashed.

I have late 04 with the 04 motor. So looks like I have to do nothing. The only reason I ask is because I just hooked up my new insight cts last night and started truck for the first time in a few weeks and it shows no boost PSI ( at idle ) is that normal? I have not driven yet. It was late last might when I finished, so no road test yet, and what is a normal boost psi , cruising at around 45?

[Qholic]

0-1 psi of boost at idle is normal

My CTS shows 0 psi at idol. Always has.
