Hello Mates,


Recently upgraded my 2008 307 (CAN) from the AL4 to the AT6/AM6 transmission from a 308/408/C4 2.0, the car handles much better now, although the transmission is from a EW10A engine I believe the control module was replaced from the parts yard by mistake (I guess they sold the module and fit another one to sell me).


The transmission runs fine, all gears engage smoothly, but I believe the module is telecoded/calibrated for the THP engine, because:


The torque coupling converter is very aggressive, its easy to spin up the wheels at 1st gear, I've driven a 308 with the EW10A + AT6 powertrain and the gas pedal feeling is different, although here in Brazil the 307 and 308/408/C4 are all PF2 cars)


I get these errors, the transmission module (TCM) expects the steering angle values on CAN which the car is not fitted and the BSI is set as not present.

The codes seems to be related to no ESP signal, of course, there is no ESP in the car! How to config the transmission to not expect it?


U1105 Fault in communication on the CAN network with the steering wheel angle sensor : No signal
U1308 Fault in communication with the engine ECU on the CAN network : No signal - THIS CODE IS PERMANENT, THE OTHERS APPEARS AFTER A FEW KMs
U1313 Fault in communication with the ABS/ESP ECU on the CAN : No signal
U1318 Fault in communication with the built-in systems interface on the CAN : No signal



I´ve access to diagzone, FAP and diagbox tools, and I need to access the car as if were a 308, as a 307 I cant config anything (incorrect values)


As I understand the TCM is set as the ESP should be present and is not finding it, but I CANNOT config it off. Not with diagzone or diagbox.


So, is my module from a THP engine or from a EW10A?
Can I config it correctly to match the EW10A and NO ESP?
Should I replace the TCM from EW10A engine? if Yes, what would be the order code (96xxxxxx) I'm looking for?

Greetings
