    Awesome. Now where's the Z31 listed?

        I fail to see the humor in this.
        *I am scratching the skin off my skull at the moment bouncing between two FSMs.
        87 and 88 trying verify that it is a plug and play ordeal with what I'm doing.
        *So far it looks to be the same.
        ^^Anyone care to validate/double check.
        -Chassis is an original '87 turbo federal, 5spd...ecu going in is an '88 n/a federal auto.
        **People have spoken about the need to repin the efi harness in certian circumstances....Everything looks the same.
        (besides the obvious that I am doing, adding resistors for the new injectors, going to pre-recall injector wiring, wiring in the n/a idle control plug for the n/a idle control, not using a det. sensor, that's it, as far as I can see)
        8)

          Let me know how that works out, I recently did a swap to turbo on my 88na and I still need to figure out how to wire in the o2 sensor and detonation sensor...

            Yeah, the FSM makes my head hurt.
            If they would have used two more pieces of paper when making the diagram it would make life alot easier.
            Overlaying both Vg30E and VG30ET diagrams on one paper makes a mess.

                mine was easy to slap in.

                84Na to a 88NA ecu. just add resistors.

                i can really feel a difference in power. :wink:

                  Pass on the det sensor....waste of effort(trust me)
                  As far as the O2 goes...thats simple.
                  Wire the three wires from the O2 sensor pigtail as follows:
                  Red O2 wire to Green/White wire in engine bay O2 harness
                  White O2 wire to any decent chassis ground
                  Black O2 wire to black wire in engine bay O2 harness

                  **I can handle these simple things, I don't know why I am getting stuck....possibly because I keep repeating over and over in my head that there people saying that pins need to be swapped?

                        I'm lost as to what you're needing help with. You're adding resistors for the inectors, I'm assuming you're using the romulator to edit the ECU, what else is there at hand?

                        FWIW, I've been running an 88T ECU on my 87 NA chassis with a 9:1 88T motor with no issues. I opted not to use the det sensor either.

                          The issue is this:
                          I have an '87t that is under going multiples of modifications/upgrades all at once.
                          *If there is an issue with any electrical, it is going to be a nightmare to figure out.(it has my concern)
                          ~It has been said that there are some wiring differences in the EFI harnesses for the swap I am doing with the ecus.
                          The Nistune Ecu I am going to be using is a Federal '88 n/a auto.
                          I do not see any wiring that is different in the FSM between the 1987 and 1988 years over on the ECU side.
                          **Where I see the differences are in the EFI harness. There is obviously differences between n/a and turbo, but there is differences between the years as well. It is boggling my mind everytime I look at it.
                          ^^^I was hoping to have a little relief and verification of what I'm seeing I need to do by having someone post thier findings of what they believe would need swapping in the harness....
                          Someone work with me please.

                            My findings thus far:
                            *I need to know if I am looking at this right! Look like I need to move 3 pins/wires? I know there is no need to be concerned with stuff that is listed, but doesn't apply(120, 80, and 29).....

                              I don't know how much this helps you but: when i converted my 87 N/A i converted my ECU by doing the following:

                              Unplugging the N/A ECU
                              Using turbo injectors from an 88T car
                              Plugging in the Turbo ECU from an 84T car
                              Start the car and drive it away.

                              I made absolutely no wiring harness modifications of any kind, and for the record my harness is post injector service campain. The car gets good gas mileage, idles flawlessly, doesn't detonate under boost.
