  • ECU interchange question

    Wondering if which ECU's are right for which car would be of interest. Thought maybe someone with more knowledge than I could help.

    I am wondering about S13's SR ECU's right now. Is an E5 and 62 interchangeable?

    They are interchangable, in that both will run your SR (as long as it isn't a TypeX).
    The only thing is that the 62/63 is for the Skinny o2 sensor. E5 is for fat o2 sensors. Mixing the two can cause rich condition.

        Another thing to consider:

        Any blue connector ECU can be used to power any blue connector harness/engine, so long as the rom is tuned accordingly.

        I have a 1.6 Sentra ECU in my car hehe. Sold that SR one for some cash, and used a junkyard one for my JWT setup

          Not really true.

          Isn't 1.8 Sentra a white plug, as it's 2002/3 and OBDII?

              I always use go by the proper part numbers just to be certain.

                Also be aware that a COP ECU (such as 50F00 for redtop) is not compatible with a distributor ECU, and vice-versa.

                    Does anyone know if a KA AT ECU can run a KA MT rom? Or the two ECU's arent totatlly the same.

                      Yes, you can run an MT bin on an AT ECU.

                        Yes, you can run an MT rom in an AT ECU, provided you also use an MT harness. To my knowledge, hardware wise the ECUs are the same, except the AT ECU has the extra I/O for the AT control unit populated on the motherboard.

                          I'm looking for the white plug (with a length of harness) that comes on the OBD2 ECUs. Anyone can help?

                            It'll work. Just got to jump out the park/neutral switch, or use the circuit to wire up your own clutch-start interlock. If you have cruise control there's some tricks to make it work. I seem to recall reading that the auto ECU doesn't have the speed limiter that's in the Manual ECU.

                            I just converted a 1997 240sx with OBD-II auto to manual last week and didn't swap ECU's.

                            OOPS! I see you asking about ROM-tunes? I'll defer that question to the ROM-tuner types...,
