I see these are the same, but I wonder how much the same?

I went to the JY today to find a replacement for my 16197427 that is acting weird. I come back with something that says both 16197427 and 16196395 on it. Now it gets better, my old cal is BJYL, my new cal is BJLH.

I should be able to burn my old BJYL bin just fine right?
The two cals are identical it seems, except for the year, the prom ID, scan ID and "ECM". But why would I have both part numbers on it?

Adding to my luck, it was already pulled and laying in the vehicle.

 

They are basically the same ECM. There are minor differences in the PCB layout between them. But that could be a revision change too.

I looked them up on BCC Find and even though they came in 2 differant number ECM when looking at them they are both $OD. So you should be good to go!

I'm running a manual $OE bin in a 16197427 which is usually $OD...
