Probably easier to socket the manual ecu. I'm not sure but I believe changing from auto to manual required switching a resistor position. I'm not sure which one though.
Thanks buddy what does socket it mean? And the reason I ask is I got 3 pr4 ECUs and 2 are manual and one auto but the auto one is chipped and I wanna be able to run the chip so I get better performance it works in my car now but it runs funny at idle and take off but the chip makes it really fast
