Anybody know what a V8 Motronic with the part # 441 907 404C is? My version of ETKA says that's a valid V8 ECU number that can be replaced by a 441 907 404H, which could be replaced by a 441 907 404HA, which could be replaced by a 441 907 404HB, which it lists as the proper ECU for an auto tranny 90 V8.
