RE: PCMforless tuning options (send in, core, loaner)
Well not to contradick you...But Mine worked fine as soon as I plugged it in..I only had to reset the oil change reminder and take it to the dealer for them to reset the relearn calibration for the crank angle sensor of the engine to clear the Service engine light...and all I gave them before they sent the brand new never been in my truck PCM was my VIN.

The Security relearn only takes 30 minutes, is very easy and is mostly waiting. There are no tools involved. Even a caveman csan do it.

All that is required for the loaner is it to be flashed with the VIN and that should be easy for Alvin to do before he sends it and then you won't have to go through all that learning mode.

Read again " Actually 90% of the time you will have to do a security relearn. "
There are certain number of security codes like vats pellet codes. Each controller has its own. When they did your CASE relearn they probally also did a security relearn (PCM BCM relink)

This might of been ask before if so sorry.
What is the procedure of the security relearn.
Thanks

Alvin (or anyone else)
I stayed up past my bedtime to swap out the loaner PCM. I got to work on time this morning so everything worked fine. Alvin, my PCM is on it's way.
I do have a couple of observations and questions:
- During the security relearn procedure (which was necessary on my H3), I noticed that the security 'light-lock' stayed on for approximately the stated mandatory minutes. Then it turned off. Was this coincidence? I waited 5 minutes extra just in case. Point being, I could have been in bed 5 minutes x (number of cycles) earlier if the indicator light 'turning off' is an indication that it is OK to proceed to the next step.
- Also, I wasn't sure if I could exit the vehicle during the process. Didn't want to chance it at 1:30am and possibly start the whole process over.
As far as the connectors are concerned, mine were very snug, but did come out fairly easily. It did help to look at the loaner PCM to see how the pins are oriented and to determine where the inline connector ends and where the socket begins. Also, and very critical to successfully removing them is an explanation of the grey 'seating' clamp. The connectors won't release from the socket unless the grey clamp is fully in the up position. After installing the loaner PCM these clamps seated the connectors perfectly when returned to their front position.
Looking forward to receiving my newly tuned PCM.

I don't think it's a good idea to post it here, considering it will make it alot easier for people to steal them [:@]

They all must be different for each truck for people to steal them.

You can. I did and it worked fine. You won't ever have to do it again though so it doesn't matter
