    but it still works well for me so i'm still happy
    The MPI is not there to control anything in closed loop. Your analog out at idle should be at 2-2.08v. If it's there, then the stock ECU is doing what it is supposed to do. If it's off, then youwould have a CEL for being too lean. The stock injector control is only ment to be done in open loop, like when the switch is on. You cannot control the the fuel in closed loop because the ECU will want to pull all of it out to get to the 14.7 range. Mine fluctuates between 14.5 to 15.1 and that's what the stock ECU is doing all by itself and it's happy with that. Running 15 at idle doesn't matter, there's no load on it so the ECU is cool with that. You shoudl even be fluctuating on the highway just cruising also. Anytime you are not in boost, it should fluctuate.....that's normal.

    yeah i fluctuate when i'm not boosting, at idle between 14.5 to 15.5, and when i'm cruising the range is higher. when i boost, it holds steady at whatever number it is, right now untuned it holds steady at 10.0 (although it is probably lower than that), and sometimes i've seen it hold steady at 10.2.

    Did you throw out the extra injectors?
    Did you throw out the plugs?
    You drop the car off telling me you are running 8psi. Your car had full fuel cut/shut down at 9psi when it came in. I see 12 psi and you cannot reduce the boost with your set up. The wastegate needed to be removed and made to be adjustable. I told you like I tell everyone that I will not tune a stock engine that high in boost. If you did have a pin in the PCM wire then yes that would be a problem. We do not install pin in the harness. I show up at 8:30am and see your car park out front. You are now where to be found. You show about 10:00am, you and your group had gone to get something to eat. We talk about the car and you ask question, I do not try to rush you away and give you as much time as you need. Now I am already starting over 2 hours late. The shop hours are 8:30am to 1:00pm and the weekend. Right off the bat you have big time fuel cut and shut down at 8 psi. I tune that out but now I see 12 psi. I try to tune the car by keep lifting the throttle at 10psi. I do feel a cut out but not sure what it is at the time. I ask you if you can leave it for the weekend and you tell me no. OK then you can come pick it up. You make me wait over an 1 1/2 hours to pick it up. Then when you show up you tell me that you are going to leave it anyway. While I waited for you I checked you plugs and for leaks. Your plugs gapped at .045 and were one heat ranger cold then they should have been. I order the right plugs on monday and wait until 3.30pm for them to get it. I put them in and try to tune the car but I am still getting a mis at higher boost every now and then. You do not want me to remove the wasegate to fix it and lower the boost. So you tell me that you will come and get it by 5.00pm. You show up a around 6:30pm. No problem I got all of the paper work done while I was waiting for you any. I would be ready to leave right after you came and got your car. We talk about your car for about 30 minutes you ask questions. I did not rush you out the door. You drive your car out of my lot and leave. I close down the shop and leave. On my way out I see you and your group were out front taking a smoke break. We both wave good bye and I drive home.

    I come in the next day and find a voice mail from you. I call back right away and leave you a voice mail. You never call me back or e-mail me. Then I find this thread. This forum rocks, people on it are just such great guys.
