L99/6L80E Swap

[Cyboula]

Hello my friends!
Im currently helping a friend to do a L99 and 6L80E swap from a 2013 Camaro SS to a Ford F100 Truck.
The engine is installed already, but we're experiencing some trouble to communicate with the ECM.

The problem is, i can only establish communication with the TCM.
As soon as i try to read from vehicle, the "No VIN was detected" screen pops up with nothing to select in the combobox.

When i cancel it starts to read immediatly, but only the TCM Info.
When it finishes, There's nothing on the "OS", "ENGINE" and "ENGINE DIAG" tables.

Any ideas what can be causing it not to communicate ?

I'm attaching the Tune and some Screenshots i took today.

Thank you !!!

Check "High Speed Communications Enable" circuit to the ECM. It must be pulled to Ignition through small fuse (3A).

Is this a blank ECM? Crate motor? Pullout combo?

Sorry about the delay my friends !

You mean the fuse must be blown ?
Sory verlon, i think i didn't understand your tip

My friend bought the engine/transmission (With the ECM and harness) from a used car.
I Don't know if was totalled or anything like this...
will the Immobilizer stop the ECM Communications ?
I Don't think so... am i right ?

Thank you for all your help my friends !

I Don't know if it helps, but it have no SRS Module ATM.
Could it be the cause ?

There is no stock fuse in this circuit. When swapping engine you must connect it to Ignition unless you brought BCM with harness to the new vehicle.

The BCM is here. The only thing missing is the airbag module.
When I try to read the ECM hptuners instantly asks for the VIN.

Question.
Will VATS prevent my comm. With the ECM ?

No, VATS will not prevent communication.
