GMPP LS3 crate engine E67 ECU Slave

[MPC001]

BTW - 12625892 is an E38 09 slave OS. E67 09 slave OS most likely 12625997. Maybe getting the right slave OS in will de-brickify it.

My truck: 3GTEK233X9G145458
Donor ECM that worked after primary flash reprogrammed w my trucks file via CAN bus:
1GCEK29089Z288356 2009 Silverado
Donor ECM that only worked up to about 60% throttle, reduced power mode after that:
1GCGG25CX91141738 4.8 express van
I then used the u-link and can bus to program the slaveOS and slaveCAL files which bricked the ECM.
So far I’ve programmed the slaveOS and slaveCAL files, 12625892 and 12626693, using CAN bus script from two different sources with no change. I’m wondering if I’m using the correct can bus script.
