I've got an auto FD, and I've found a deal on upgraded ECU....however its a manual ECU. After reading through several older threads it sounds like the two ECU's can be used together, the manual upgraded ECU running most of the car along with the engine fuctions, while the auto ECU is mantained simply to run the auto tranny. Is this correct? Question is now, how do I go about splicing them together...? I'm not the most knowledgable when it comes to the electronics side of things.
Any help would be immensly appreciated.
