This is not a question of weather or not it's possible, it's a question of will it get done with the factory gateway from the F series getting installed into the E series, or using an emulator with ISN programmed to unlock the transmission and then use XHP to flash stage 3 maps.
There is the final option of using a 3rd party controller, but that will add about another $1k to the price + mods to the mechantronic unit.
Anyone who has driven a XHP Flashed 8hp will understand why I'm doing this. If you haven't driven a XHP flashed transmission, then you need to flash your 6HP and get read to fall in love with your car all over again ( Yes, it's like that . . , . )
seanjordan20, feel free to let me know from a coding point of view if its possible (keeping the factory gateway) or if you have other experience that might help. Thanks.

 

You're trying to open up a can of worms. I'll try to explain it as plain as I can.

The factory module is a no. The gateway (ZGW) for an F series is also the FEM. They are the same module working independently which also talks to the EGS including the CAS. So many communication differences in the F series network wise (PT-CAN/2, LIN, Flexray, etc). They just communicate differently.

Even using a F series 8HP in itself can not be done. You have to unlock and virginize the ISN by bench (which can easily be done using the correct software) but afterwords you will not be able to flash the BTLD, HWEL and SWFL files to it because it rejects any E series files because HWID or ZBNUMBER does not match. You can add FA and generate but it will not take even though it's talking on address 18.

The more realistic approach is to use the 8HP out of E series. Even though they did use the same trans in the F01 they changed the network for it to work with all the updated modules which the E series does not have especially when talking about combining ZGW with the new FEM. With using the E series 8HP it's a task that can be done but it will definitely be a long project. I think there was a guy in 2021 doing an E series 8HP swap from 6HP and the last I read he hadn't completed it yet. I think he was at an 80% solution the middle of last year. He was taking his time.

I hope this made sense to you.

 

Last time I checked, the Gateway module is responsible for 5/6 different bus signals including ethernet and MOST signals. The 8hp only uses PT CAN. Using the Emulator will take care of the can signal and the ISN. For some reason if that doesn't fly, There is always the TurboLamik option. They have an after market ECU that controls the 8HP. But you do have to modify the mechantronic for the interface to work. (You can also add a clutch pedal to the setup for the die hard manual fans-but its sequential shifting - no dog box)

 

The Gateway communicates on the MOST. The FEM passes data to the ZGW through BUS drivers. The FEM and ZGW are 2 modules in 1. Everything rides on the FEM except the Ethernet allowing communication throughout the car via the flexray. The flexray is the most sensitive part of the car and once damaged (usually by updating) the FEM/ZGW needs to be replaced.

I think you are almost saying the same thing but hard to tell. In the end the F series communicates differently than the E series and handles more than the gateway for the E series via FEM. I don't know anything about the emulator or Turbolamik option because I've never had this presented before. I guess at any rate all you can do is try it to see but I'm not seeing how you will be able to flash the TCU if you don't use the F series FEM/ZGW or how the car would work if you did use the F series module. Who's knows maybe I'm not understanding the difference in the 2 series communication and just over thinking it.

 

So, how did the process of doing the swap worked out for you in the end?

 

its documented in using the CANTCU its a plug and play option. I have the parts on and plan on doing this by early next year.
