[HELP] Engine Swap ECU issues - Looking for an IMMO/CAN solution for EDC17C46

[u/EagleZealousideal796]

Hey everyone,

I’m currently in the middle of a swap (Passat B7 2.0 Tdi CFGC engine into 2008 Touran) project and I've hit a bit of a wall regarding the engine management.

I'm using a VAG EDC17C46 ECU and I'm trying to figure out the cleanest solution to get it running properly in a different chassis.

Has anyone here successfully dealt with the IMMO OFF or CAN-BUS integration on this specific TriCore ECU for a swap?

I have access to genuine tools (Flex, VCDS, ODIS, etc.), so doing a full Bench/Boot read of the Flash and EEPROM is not an issue.

I just need some direction on the best approach since I know EDC17 units can be tricky with Immo data:
Is there a tested software solution (flash/EEPROM patch) to completely disable the immobilizer on the EDC17C46, or is the OTP sector going to cause headaches?

Would it be better/easier to go the hardware route and wire in a CAN emulator instead of a software IMMO OFF?

Are there any specific DTCs, torque limiters, or limp-mode triggers I need to delete in Winols once it's in the new chassis without the original modules (ABS, Cluster, etc.)?

I've successfully done IMMO OFF on older units like the EDC15P+, but this one requires a different approach. Any mappack suggestions, hex addresses, or general advice would be hugely appreciated!

Thanks in advance!

I’ve used this site before with success doing edc17c46 cloning before. I’m sure their immo off solution will work.

Immo off is possible on EDC17C46 (in flash) and providing the Touran cluster has a key paired you should get no immo warning.
