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.
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. :)
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...
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...
From his "About" and where this was posted it's a 420A.We shouldn't have to ask or go looking for that critical information. The onus is on the poster.
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...
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?
Lot of changes to the procedure between the original FSM, the TSB's and the later manuals.I want to say that the techs at the dealership were the ones that shared this tip with me but I can't say with any conviction. I wouldn't be surprised, I had a good relationship with the service manager...
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.
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.
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.
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. Once I then knew it was correct I recommended it in whatever timing belt threads I replied to. Who I heard the technique from originally is lost to necrotic brain tissue but it's...

I'm not sure what flavor of math is going on here?9/64" = 0.140625" * 25.4 = 3.571875 mm
5/32" = 0.15625" * 25.4 = 3.96875 mm
1/8" = 0.125" * 25.4 = 3.175 mmFSM says 3.8 - 4.5 mm gap on a 6-bolt tensioner but it also expects that there isn't a wear dimple in the tensioner arm which would...
I don't think that was the issue, he's already used to SI units. The silly needle was in the way on the top one so it's not a literacy issue either. Just a difficult picture unless you zoom or look close.I didn't for a second think Curt you really didn't know what they were for but that you...
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...
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...
So no change and this remains unresolved.He, whoever he is, says his black top CAS doesn't have a lip and yours clearly does. Has he provided photo proof of his claim? It would seem like covers with a machined recess would work for both if there is two different bodies.I wish I could help...
A dealership's shop was full of special tools to do tasks by the book. Sometimes you didn't have any choice but to buy the special tools but usually those not working for the dealerships would improvise and as mentioned looking around for something thin and strong to use to cut the seal leads to...
It's been a few years since I've pulled the pan on a SBC but what I remember was a cork gasket and to get it to not leak over time you often have to torque the bolts down to the point of distorting the pan.Or am I having age induced hallucinations?On a 4G63 you're more likely to have bent...
The ECU is the ground, the injector driver (one per injector) in the ECU pulls the one side of the injector coil to ground while the other side is connected to power (via the injector resistor on the turbo cars).Please fill out a profile for your car so we know what kind of 99 it is. There is...
Refering you to your prior thread. Here's what you had which is one range colder than stock. NGK bpr7es spark plugs.It's not normal to be fouling your plugs but when you keep flooding the engine it takes it toll on them. Bad tunes don't help either.Stick with NGK copper plugs, they have...
You use F10 to open the Captured Values dialog and add the new parameters.
Once you have them in a log you use F9 to display them.http://www.ecmtuning.com/wiki/ecmlink101datalogging?s[]=capture

In this one you have MAF Comp values that add airflow at low flows, that will change the logged airflow. You might want to check the MAF and see it it's been modified by removing some of all of the honeycombs in the front of it.If you want to continue playing with these settings enable the non...
