PCM learning process???? Need help.
I will be ready with my heads/cam swap the next days and then I will install the new PCM (special programmed) that I got.
What will I have to do so my car learns the new PCM.
I´ve been told there`s something like ignition on for 10 minutes, then off...... or something like that.
Can´wait to start the engine.
Cant wait for the first WOT run.
Can´t wait to push it in the 9´s with a big shot NOS :D
Thanks,
Michael

If you sent your PCM out for tuning you probably don't need to do anything but install it. If you've swapped PCMs, try this:

I think there's a faster way to do it if you have a Tech-2.

:confused: Isn't the point of a PCM reset to clear the PCM, so it can relearn based on your new mods?

Directly after install you are supposed to:
1) Insert key into ignition and turn to the "On" position but, DO NOT START THE ENGINE.
2) Pop open the fuse box cover and remove the two 10amp fuses from position numbers 16 & 23.
According to the manual there are 2 fuse boxes. Use the engine compartment fuse block for this procedure.
Instrument Panel Fuse Block (wrong one): 16 is Air bag and 22 is Body Control Module - Ignition and 23 is Body Control Module - Ignition 2.
Engine Compartment Fuse Block (correct one): 16 is Powertrain Control Module A and 23 is Powertrain Control Module B.
Note. Your DIC will now display "check" messages for ABS, etc... Do not worry. This is normal.
3) Go back to your cockpit and turn your key to the "Off" position.
4) Return to the fuse box and re-insert both 10amp fuses for positions 16 & 23.
5) Go back to your cockpit and start your engine. Allow engine coolant temperature to reach a minimum of 176 degrees F. Allow engine to run at this minimum temperature for at least 5 minutes.
6) After a minimum of 5 minutes, at 176F, shut down engine and let rest for a minimum of 30 seconds.
7) Restart engine - check for DIC error codes (there should be none).
8) Drive car for a minimum of 30 miles at varying rpm settings and speeds. PCM will now re-learn and adjust for the new air flow and air temperature at the intake.
If error codes persist, repeat steps 1-7. Make sure fuses are properly inserted before repeating steps. Do not void the sequence outlined above. If you do, restart sequence from scratch.
Steps 1-4 are also necessary if you ever disconnect your battery or lose power for any reason.

Re: PCM learning process???? Need help. (TooManyIDs)
We're not talking about a simple reset of the PCM. The PCM and BCM exchange passwords as part of the anti-theft system and these components need to be resynchronized if you replace one.
BTW, your PCM is always learning. ;)
