So long story short my LBZ was totaled by a drunk driver. So I am trying to make lemonade from the lemons of this situation.

I've since decided to swap the drivetrain into a newer gen platform and need the LMM ECM to be able to communicate with the newer gen controllers.

Is there an easy way to transfer the LBZ tune from the LBZ PCM to an LMM one?
Or can I flash the LBZ PCM to an LMM PCM?
I admittedly haven't checked to the PCM's yet to even see if they are the same as I only have the LBZ one.

Thanks gents
