Can anyone tell me if the LBZ and the LLY/LRX are using the same electonics with regard to the Engine Computers?

I'm asking because the Performance Product manufacturers are telling me that they will not be making items for the LLY/LRX in the 2005 C4500 Chevy.

From what I have heard they are totally different.

I think I posted this on the wrong FORUM.

I just discovered the LBZ Electronics Forum, where I should have posted this inquiry.

Can it be moved, or should I repost there?

The 2006 LBZ and 2006 LLY use the same engine electronics. It's all Bosch controls but I do not know what the LRX uses.
