Hey guys, you all know I have the swap going from the 2001 to the 2002 going on. The motor's in and it will be running with about an hour and a half of work tomorrow morning. What I'm wondering is, will my tuned PCM from Overkill work in the 2002 without a CASE learn? or am I going to need to re-do the CASE learn?

I want to get this Overkill'd PCM in the 2002 as soon as possible. Is there ANY way to do a CASE learn without the snap-on tool or a tech II? When I plugged the Overkill'd PCM into my 2001 - it started without a CASE learn, could that be because I provided my VIN # with the order?

You can use an aeroforce if you have one..but you need a tool (tech 2, aeroforce, etc)

Every time the PCM sees a new engine, you need to perform a CASE learn.

I'm not familiar with what your swapping over but if you are using the PCM out of the 01 with the BCM out of the 02, you will need to change the VIN in the PCM to the VIN on the BCM.

I'm going to start a swap thread, but I took the PCM from my 2001 (Overkill'd PCM) and put it into the 2002, did the security re-learn, and she started right up with no codes whatsoever, runs and drives great. CASE learn is not necessary all the time. The motor in the 2002 is the motor that came out of the 2001, the 2002 had a bad motor.

A CASE learn is only necessary when a PCM sees a different engine (since you kept the 01 engine and 01 PCM it's not necessary), when you rebuild (i.e. swap out rotating parts), when you replace the crank sensor, or when you replace the balancer.

The car will start without a CASE learn but to ensure there are no problems down the road it's best to get it done if it wasn't done when you got the Overkill PCM to begin with.

Oh okay, gotcha. I had access to a Snap-On Solus Pro when I first got the Overkill PCM so I did a CASE learn for the hell of it. Took 5 seconds anyways. I do have the motor from the 01 in there so I guess it's fine.
