    1G 1991-1994 ECU swap into a 1990 DSM ignition wiring

    Bud, 6 and 14 are the pins that change between 90 and 91 for the MAF reset and the IPS. Pin 16 is the input for the Barometric Pressure sensor on all the 1G ECU's. Not sure what you were thinking.

    1G 1991-1994 ECU swap into a 1990 DSM ignition wiring

    Thank you I fixed both the pinout and the reference at the end to pin 5 that should be pin 4.All my reference material correctly show pin 4 as being the tach output so I clearly was the source of the error. :)

    ECMlink Weird cold start idle surge after wbo2 narrowband simulation

    Looks a lot like a 4 bar GM MAP sensor.I'll let the SD tuning guys comment but I didn't see anything fundamentally different. The AirflowPerRev is too high, the MAP reading doesn't make any sense, it look like you had to restart the car but the ECU doesn't see KeyStart @80 sec.With SD your...

    ECMlink Weird cold start idle surge after wbo2 narrowband simulation

    Looking at that log the first thing that stands out is you never reach coolant temps that would cause the ECU to enter closed loop and idle. The other thing I saw what that your Omni4Bar was all over the place and never showed a good strong vacuum. There is no signs of classic idle surging where...

    I know now. The wires coming out of the 90 CAS are black, red, yellow, white they run to a male connector. That yellow wire ends there.The car's harness has a female connector and the wires to it are 1.25 black, 1.25 red, white, black. (Ground, Power, TDC, Cam)The 91-94 CAS has a plug...

    Resolved 2GNT ECU failing Intermittently?

    Good, Alternator seems to be charging so that doesn't seem to be betting the battery run down and stall the car.

    Resolved 2GNT ECU failing Intermittently?

    I don't see how you have any data to suggest a fuel regulator or injectors.What exactly is your battery voltage doing when the car is off and again when it's idling?

    Welcome, There are some members here with 3rd generation Eclipses but the site focuses on the 1st and 2nd generation cars build between 1989 and 1999 at the DSM plant in Normal Illinois.There is a online forum that specialized in your car https://www.club3g.com you should check it out as well.

    Resolved 2GNT ECU failing Intermittently?

    People have but right now you don't have any idea of why your compression numbers are low. Could be your procedure (since that helped last time). Could be valves, or rings, or cylinder bores, or timing, or a combination of things.

    Did you mean closed loop? The trims aren't updated when your in open loop and I forget if they are even factored in the fueling math for open loop.

    2G Engine issues?

    Depending on where you are putting the bung it's not likely to last. In the exhaust manifold the temps can normally exceed 1200F. It's gets cooler the farther you get from there but it still plenty hot when it reaches the Cat.

    Resolved 2GNT ECU failing Intermittently?

    That's got to run rough as hell but I don't see how it directly relates to the described behavior. The min spec for compression is 100 psi (normal 170-225 psi) and max diff between all cyls is 25%.Your almost 50% between the worst and any other.

    I should have added lazy to the list above. I never modeled it, I just did it and then checked the result on the car.

    2G Low idle

    When it comes to idling, the issue is does the BOV leak air into the engine under vacuum? It shouldn't. Perhaps your old one wasn't leaking.Same thing for the vent on the valve cover. It needs to be connected to the intake pipe after the MAF. Under vacuum when the PCV is open it just provides...

    420A Fuel injector 4 not firing.

    If the problem is just with the Injector on #4, all that other stuff isn't likely to be related.Since you have a 420A based car your ECU/PCM is sealed up (potted) and there really isn't much you can do inside. I don't know if the 420A ECU will cut off fuel to a cylinder that is misfiring but...
